Electric field controlled second-order anomalous Hall effect in altermagnets
Arnob Mukherjee, Biplab Sanyal, Annica M. Black-Schaffer +1
Altermagnets are a recently discovered class of compensated magnets with momentum-dependent spin splittings and unusual transport properties, even without a net magnetization. In t…

Diamagnetic Meissner response of odd-frequency superconducting pairing from quantum geometry
Ankita Bhattacharya, Annica M. Black-Schaffer
We investigate the role of quantum geometry in the Meissner response for odd-frequency superconducting pairs in multiband systems. Odd-frequency pairing is traditionally associated…

Electric field induced second-order anomalous Hall transport in unconventional Rashba systems
Ankita Bhattacharya, Annica M. Black-Schaffer
Nonlinear responses in transport experiments may unveil information and generate new phenomena in materials that are not accessible at linear order due to symmetry constraints. Whi…
