Nonlinear Transport

nonlinearTransport nonlinearTransport

We develop theories for nonlinear Hall effect, nonlinear magneto-transport, nonlinear magnetoelectric effect.

  • Second/Third-order (Anomalous) Hall effect, planar Hall effect
  • Scaling law of nonlinear response, disorder-induced response
  • Nonlinear Magnetoelectric effect, current-induced spin generation
  • Giant magnetoresistant, blinear magnetoresistance or unidirectional magnetoresistance

Light matter interaction in quantum magnets

LightMatterInteraction

We utilize linear and circular dichroism to probe spin textures in quantum magnets. These polarization-sensitive optical techniques enable direct access to spin-dependent electronic transitions, allowing visualization of both long-range spin order and elusive spin fluctuations. By integrating polarization-resolved spectroscopy with symmetry-based analysis, we reveal emergent magnetic multipoles and magneto-chiral effects in low-dimensional systems. This non-invasive approach provides a versatile platform for investigating spin configurations in both collinear and noncollinear magnets, and opens new avenues for optically driven control of spin degrees of freedom.
