Role of Disorder in Third-order Anomalous Hall Effect in Time-reversal Symmetric Systems
Chanchal K. Barman, Arghya Chattopadhyay, Surajit Sarkar +2
The third-order anomalous Hall effect (TOAHE) driven by Berry connection polarizability in Dirac materials offers a promising avenue for exploring quantum geometric phenomena. We i…
Fingerprint of Non-Hermiticity in d-wave Altermagnet
Gaurab Kumar Dash, Subhasis Panda, Snehasish Nandy
We develop the non-Hermitian counterpart of a new class of collinear magnets, dubbed altermagnets, delineated by net zero magnetization with momentum-dependent spin-splitting bands…
Nonlinear anomalous transverse responses induced by Berry curvature quadrupole in systems with broken time-reversal symmetry
Srimayi Korrapati, Snehasish Nandy, Sumanta Tewari
Recent theoretical work has shown that higher-order moments of the Berry curvature, e.g., Berry curvature quadrupole and hexapole moments, can produce the leading order nonlinear a…
