Nonlinear Spin Polarization Enables Néel Order Switching in Centrosymmetric Altermagnets
Sunit Das, Sayan Sarkar, Amit Agarwal
Deterministic electrical switching of the Néel order remains challenging in centrosymmetric altermagnets, where linear current-induced spin polarization is forbidden by inversion s…
Diagnosing the origin of quantum oscillation beating in graphene
Akash Adhikary, Sunit Das, Divya Sahani +2
Magnetic quantum oscillations are usually periodic in inverse magnetic field, and their amplitude can show beating when two nearby frequencies interfere. In graphene-based hexagona…
Asymmetric Scattering Drives Large Nonlinear Nernst and Seebeck Effects
Harsh Varshney, Amit Agarwal
The nonlinear Nernst and Seebeck effects (NNE and NSE) offer promising routes for thermoelectric energy conversion in non-magnetic systems. While intrinsic mechanisms such as the n…
Observation of Time-Reversal Symmetry Breaking in the Type-I Superconductor YbSb
Anshu Kataria, Shashank Srivastava, Dibyendu Samanta +9
The spontaneous breaking of time-reversal symmetry is a hallmark of unconventional superconductivity, typically observed in type-II superconductors. Here, we report evidence of tim…
Intrinsic Gyrotropic Magnetic Current of Orbital Origin
Koushik Ghorai, Sankar Sarkar, Amit Agarwal
In gyrotropic crystals, an oscillating magnetic field induces a charge response known as the gyrotropic magnetic current. While its conventional origin is attributed to magnetic fi…
