Effect of disorder in a frustrated system

Dr. Mayukh Majumder

Department of Physics, Shiv Nadar University, India

Disorder is unavoidable in any real-life quantum many-body system. Though in several cases, the disorder often hinders us from elucidating the actual physics of a system, in some cases, unusual properties can be seen, and exotic phases can be formed due to the presence of disorder. Those interesting phases do not develop in a clean or disorder-free system. Some examples of those exotic phases include the quantum Griffiths phase near quantum criticality, spin glass, random spin singlet state, etc. In the talk, I will discuss the presence of an exotic state, namely the random spin singlet state, stabilized by disorder in a new Copper-based three-dimensional quantum spin liquid candidate.
