Intrinsic Magnetoelectric Hall Effect from Layer-Orbital Quantum Geometry
Sunit Das, Amit Agarwal
Intrinsic Hall effects, such as the anomalous Hall effect, originate from the orbital quantum geometry of Bloch states. However, in layered materials, the combined action of out-of…
Asymmetric Scattering-Induced Neel Spin-Orbit Torque in Antiferromagnets
Sayan Sarkar, Amit Agarwal
Magnetic switching in antiferromagnets relies on Neel spin orbit torque (NSOT), which originates from a current-induced staggered spin polarization of itinerant electrons. In colli…
Longitudinal Nonreciprocal Charge Transport with Time Reversal Symmetry
Harsh Varshney, Amit Agarwal
Longitudinal nonreciprocal charge transport is usually associated with broken time-reversal symmetry, either from magnetic order or an external magnetic field. Here, we show that i…
Orbital angular momentum of Bloch electrons: equilibrium formulation, magneto-electric phenomena, and the orbital Hall effect
Rhonald Burgos Atencia, Amit Agarwal, Dimitrie Culcer
The investigation of orbital angular momentum (OAM) of delocalised Bloch electrons has advanced our understanding of magnetic, transport, and optical phenomena in crystals, drawing…
