Quantum Transport Spectroscopy of Pseudomagnetic Field in Graphene
Divya Sahani, Sunit Das, Kenji Watanabe +3
Nonuniform strain in graphene acts as a valley-dependent gauge field, generating pseudomagnetic fields (PMFs) that mimic real magnetic fields but preserve global time-reversal symm…
Deterministic Switching in Altermagnets via Asymmetric Sublattice Spin Current
Sayan Sarkar, Sunit Das, Amit Agarwal
We demonstrate a deterministic switching mechanism in collinear altermagnets driven by asymmetric sublattice spin currents. Unlike conventional antiferromagnets, where combined par…
Disorder-driven Weyl-Kondo Semimetal Phase in WTe
Arpan Manna, Sunit Das, Amit Agarwal +1
In this Letter, we report the observation of disorder-driven anisotropic Kondo screening and spontaneous Hall effect in bulk WTe, a nonmagnetic type-II Weyl semimetal. We sho…
Odd-parity longitudinal magnetoconductivity in time-reversal symmetry broken materials
Sunit Das, Akash Adhikary, Divya Sahani +2
Magnetotransport measurements are a sensitive probe of symmetry and electronic structure in quantum materials. While conventional metals exhibit longitudinal magnetoconductivity th…
Symmetry-driven Intrinsic Nonlinear Pure Spin Hall Effect
Sayan Sarkar, Sunit Das, Amit Agarwal
The generation of pure spin current, spin angular momentum transport without charge flow, is crucial for developing energy-efficient spintronic devices with minimal Joule heating.…
