SUMMARY:TRR 360 Sonderseminar: Ultrafast spin-orbitronics with terahertz electromagnetic pulses Tobias Kampfrath
DESCRIPTION:Ultrafast spin-orbitronics with terahertz electromagnetic pulses\nTobias Kampfrath\nFreie Universität Berlin and Fritz Haber Institute of the Max Planck Society\, Berlin \n  \nTo take advantage of the electron spin in future electronics\, spin angular momentum needs to be transported and detected. Electric fields and temperature gradients have been shown to efficiently drive spin transport at megahertz and gigahertz frequencies. However\, to probe the initial elementary steps that lead to the formation of spin currents\, we need to launch and measure transport on much faster\, i.e.\, femtosecond time scales. \nTo achieve this goal\, we apply optical femtosecond laser pulses to induce a spin voltage in a metallic ferromagnetic layer F [1]. The resulting spin current into an adjacent layer is measured by conversion into a charge current in a layer N and detection of the concomitantly emitted terahertz electromagnetic pulse [2]. Interesting applications such as terahertz spin-conductance spectroscopy [3] and the generation of ultrashort terahertz electromagnetic pulses emerge [4]. In all cases\, the emitted terahertz signal arises from regions close to the F/N interface\, thereby making spintronic terahertz emission very interface-sensitive [5] \nThis methodology can be transferred from the spin to the so far highly unexplored orbital angular momentum of electrons. We obtain new insights into orbitronic phenomena on their natural time scales\, for example\, time-domain signatures of giant propagation lengths of orbital currents in tungsten [6]. \nFinally\, one can implement a reciprocal experimental scheme and use intense terahertz electromagnetic pulses to drive electric currents and control magnetic order on ultrafast time scales through\, for example\, Néel spin-orbit torques [7]. \n  \nReferences[1] Rouzegar et al.\, Phys.

SUMMARY:TRR 360 Sonderseminar: Structure and magnetism of LMO/SMO superlattices Vasily Moshnyaga
DESCRIPTION:Structure and magnetism of LMO/SMO superlattices \nProf. Dr. Vasily MoshnyagaI. Physikalisches InstitutGeorg-August-Universität Göttingen \nHeterostructures of strongly correlated oxides\, like superlattices (SLs) of (LaMnO3)m/(SrMnO3)n ((LMO)m/(SMO)n)\, provide a rich platform for searching emergent phases at the interfaces as well as to design artificial electronically/chemically inhomogeneous materials to study the manifestations of electron-spin-lattice correlations in reduced dimensions. We studied the structure and magnetism of the LMO/SMO SLs prepared on SrTiO3(100) substrates by metalorganic aerosol deposition (MAD) technique. The role of interfacial charge transfer in the high-TC emergent ferromagnetism and the interrelations between the octahedral tilt/rotation angle\, controlled by LMO/SMO ratio\, and magnetic/thermal properties have been elucidated. Further on\, we have grown LMO/SMO SLs with gradual La/Sr compositional modulations on the scale 5-10 u.c. and studied their role in the development of high- and low-temperature magnetic phases. We propose a route to grow strongly correlated heterostructures with modulated electronic properties at the nanoscale. \n\n\n\n\n\n\nVenue

SUMMARY:TRR 360 Sonderseminar: Microwave spectrum analyzer based on a rapidly tuned spin-torque nano-oscillator Andrei Slavin
DESCRIPTION:Microwave spectrum analyzer based on a rapidly tuned spin-torque nano-oscillator \nAndrei Slavin \nDepartment of Physics\, Oakland University\, Rochester\, MI 48309\, USA \nA spintronic method of ultra-fast broadband microwave spectrum analysis is proposed. It uses a rapidly tuned spin torque nano-oscillator (STNO) and does not require injection locking. This method treats an STNO generating a microwave signal as an element with an oscillating resistance. When an external signal is applied to this “resistor” for analysis\, it is mixed with the signal generated by the STNO. The resulting mixed voltage contains the “sum” and “difference” frequencies\, and the latter produces a DC component when the external frequency matches the frequency generated by the STNO.  The mixed voltage is processed using a low pass filter to exclude the “sum” frequency components and a matched filter to exclude the dependence of the resultant DC voltage on the phase difference between the two signals. It is found analytically and by numerical simulation that the proposed spectrum analyzer has a frequency resolution at a theoretical limit in a real-time scanning bandwidth of 10 GHz and a frequency scanning rate about 20 MHz /ns\, while remaining sensitive to signal power as low as the Johnson-Nyquist thermal noise floor. \n    \n Andrei Slavin received PhD degree in Physics in 1977 from the St.Petersburg Technical University\, St. Petersburg\, Russia.  Dr. Slavin developed a state-of-the-art theory of spin-torque oscillators\, which has numerous applications in the theory of current-driven magnetization dynamics in magnetic nanostructures. His current research support includes multiple grants from the U.S. Army\, DARPA\, SRC and the National Science Foundation. This research involves international collaborations with leading scientists in many countries\, including Germany\, Ukraine\, France\, Italy\, and the United States. Dr. Slavin is a frequently invited speaker at magnetism conferences around the world.  \n   Andrei Slavin is Fellow of the American Physical Society\, Fellow of the IEEE\, and Distinguished Professor  and Chair of the Physics Department at the Oakland University\, Rochester\, Michigan\, USA. \n\n\n\n\n\n\nVenue

SUMMARY:TRR 360 Seminar:Exploring quantum impurities and measurement backaction via tensor-networksOded Zilberberg
DESCRIPTION:Exploring quantum impurities and measurement backaction via tensor-networks \nOded Zilberberg \nUniversität Konstanz \n \nTensor networks allow us to compress and efficiently represent one-dimensional many-body states. This relies on truncating small correlations and entanglement along the system’s length. At the same time\, the representation provides easy access to these correlations. My talk will be divided into three parts: (i) I will introduce a mesoscopic coupled quantum-dots system\, map it onto a Wilson chain\, and show how to study Kondo physics via the tensor network correlations as order parameters\, (ii) I will introduce how the tensor network description of a mixed state provides an easy-to-read entanglement measure for open systems\, and (iii) show how the entanglement measure allows us to better understand measurement-induced transitions (MITs).  \n \n\n\n\n\n\n\nVenue

SUMMARY:TRR 360 Seminar: Quantum criticality on compressed lattices Markus Garst
DESCRIPTION:Quantum criticality on compressed lattices \nProf. Dr. Markus Garst\nKarlsruher Institut für Technologie \n  \nAt a quantum phase transition\, the ground state of a system changes as a function of a non-thermal control parameter. In a solid\, the associated quantum critical degrees of freedom generically couple to the crystal lattice. This coupling is potentially able to change the universality class of the quantum critical point. We discuss various scenarios where this is realised. The coupling is necessarily non-perturbative when the order parameter couples bilinearly to strain as it is the case for quantum critical endpoints or nematic quantum criticality [1]. If the strain couples only to the square of the order parameter\, it is non-perturbative at weak coupling if the effective dimension d+z\, with the spatial dimension d and the dynamical exponent z\, is smaller than 2/ν\, where ν is the correlation length exponent. This criterion is\, for example\, marginally fulfilled at a Lifshitz transition of a two-dimensional metal like Sr2RuO4 [2]. We discuss in detail the quantum phase transition in the O(N) universality class with dynamical exponent z=1\, and we show that non-perturbative effects might also arise if this criterion is not fulfilled but the coupling exceeds a critical threshold [3]. \n[1] I.

SUMMARY:TRR 360 Seminar: Controlled quantum materials Daniele Fausti
DESCRIPTION:Controlled quantum materials\nD. Fausti 1\,2\,3\n1 Department of Physics\, University of Trieste\, Trieste\n2 Elettra Sincrotrone Trieste S.c.p.a.\, Trieste\n3 Department of Physics\, University of Erlangen Nuremberg \nThe rich phase diagrams of many transition metal oxides (TMOs) is the result of the intricate interplay between electrons\, phonons\, and magnons. This makes TMOs very susceptible to external parameters such as pressure\, doping\, magnetic field\, and temperature which in turn can be used to finely tune their properties. The same susceptibility makes TMOs the ideal playground to design experiments where the interaction between tailored electromagnetic fields and matter can trigger the formation of new\, sometimes exotic\, physical properties. This aspect has been explored in time domain studies [1] and has led to the demonstration that ultrashort mid-IR light pulses can “force” the formation of quantum coherent states in matter\, disclosing a new regime of physics where thermodynamic limits may be bridged and quantum effects can\, in principle\, appear at ambient temperatures. \nIn this presentation I will review our recent results in archetypal strongly correlated cuprate superconductors and demonstrate the feasibility of a light-based control of quantum phases in real materials [2\,3\,4]. I will then introduce our new approaches to time domain spectroscopy going beyond mean photon number observables [5-10] and show that the statistical features of light can provide information on superconducting fluctuations beyond standard linear and non-linear optical spectroscopies [11]. Finally\, I will elaborate on our current research effort to use cavity electrodynamics to control fluctuations in matter and thereby the onset of quantum coherent states in complex materials [12]. \nReferences:\n[1] Advances in Physics 65\, 58-238\, 2016\n[2] Science 331\, 189-191 (2011)\n[3] Phys.

SUMMARY:TRR 360 Seminar:  Broadband optical studies of kagome metals Ece Uykur
DESCRIPTION:Broadband optical studies of kagome metals: Electronic correlations\, localized\ncarriers and phonons\nEce Uykur\nInstitute of Ion Beam Physics and Materials Research\, Helmholtz-Zentrum\nDresden-Rossendorf\, 01328\, Dresden\, Germany \n  \nKagome metals attract a lot of attention as materials that combine two extreme features in their\nelectronic structure: Massless Dirac fermions with linear band dispersion and flat bands hosting massive\nlocalized electrons. Topological nature of the former and strongly correlated nature of the latter lead to\nmultitude of exotic phenomena\, including quantum anomalous Hall effect and novel states\, such as axion insulators. The electron dynamics of these systems is the key for understanding the proposed exotic phenomena. \nTo this end\, we employed broadband infrared and ultrafast pump-probe spectroscopy studies on\nseries of kagome metals. In this talk\, I will summarize the optical fingerprints of itinerant and localized\ncarriers\, signatures of electronic correlations\, and the interplay between unconventional carriers and\nphonons in these systems. \n  \n\n\n\n\n\n\nVenue

SUMMARY:TRR 360 Sonderseminar: The unusual electron transport in metallic Kagome nets Philip J. W. Moll
DESCRIPTION:The unusual electron transport in metallic Kagome nets \nProf. Dr. Philip J. W. Moll \nMax Planck Institute for the Structure and Dynamics of Matter \n  \nMaterials that can host different states of electronic order form a recurring theme in physics and \nmaterials science\, and they are of particular interest if they are coupled strongly. A famous \nexample are ferroelectrics\, in which electric polarization and magnetism not only coexist but are \nstrongly linked. This both unveils a rich physics of correlated states\, and also opens unexpected \napplication avenues as the coupling promises to manipulate one state by a stimulus that primarily \nacts on another – say switching magnetism using electric fields. \nRecently\, materials based on the structural motif of the Kagome web have attracted significant \nattention for their tendency to host such strongly coupled phases. In particular\, the centro- \nsymmetric layered Kagome metal (K\,Cs)V3Sb5 have entered the focus of experimental and \ntheoretical research. They host a charge-density-wave type transition at elevated temperatures \n~100K\, followed by a superconducting transition at 3K (exact values depend on composition). \nYet there is another type of electronic order which thus far eludes exact microscopic \nidentification. A series of experimental probes detects the onset of anomalous behavior around \nT’~30-40K\, including thermal Hall\, µSR\, NMR\, magnetic torque\, Kerr rotation. The anomalous \nlow-temperature state carries the characteristics of a chiral\, nematic and time-reversal-symmetry \nbreaking fluid (all of which are under most active debate currently). \nYet what crystallizes out of the current state of experimental data is a highly entangled system \nwhich is extraordinarily responsive to external perturbations. This materials main strength is \nequally its weakness\, the unusual degree of coupling between states can hinder its systematic \ninvestigation. However\, it is already clear that it provides a platform to explore strongly coupled \ncorrelated phases\, and as a result it displays a thus-far unknown electromagnetic response\, a \ndiode in which the forward direction can be switched by the application of a magnetic field. I \nwill review the current state of the field\, and discuss ongoing projects in my department. \n  \n[1] C. Guo et al.\, Nature 611\, 461-466 (2022) \n[2] X.
