SUMMARY:TRR 360 Seminar: Some exotic phases for spin-1/2 on the triangular lattice Sylvain Capponi
DESCRIPTION:Some exotic phases for spin-1/2 on the triangular lattice \nProf. Dr. Sylvain Capponi \nLaboratoire de Physique Théorique\, Université de Toulouse\, CNRS\, UPS\, France \n  \nThe triangular lattice is at the origin of magnetic frustration both for Ising or Heisenberg models\, as shown by Wannier and Anderson respectively. Hence it is a natural testbed to stabilize unconventional phases of matter. In this talk\, I will present two recent numerical studies discussing \n(i) the possibility of a Dirac spin liquid in the J1-J2 Heisenberg model [1](ii) the possibility of a supersolid phase in the XXZ model [2] and its relevance to recent scattering experiments on K2Co(SeO3)2 \n  \n[1] A. Wietek\, S. Capponi\, and A. Läuchli\, Phys. Rev. X 14\, 021010 (2024)[2] S. Capponi and A. Läuchli\, in preparation \n\n\n\n\n\n\nVenue
