Nonlinear Ohmic electromagnetic response
Anwei Zhang, Zheng Cai, C. M. Wang
We systematically investigate nonlinear Ohmic responses in second-harmonic generation and bilinear magnetoelectric effects within the Matsubara Green's function formalism. The opti…
Quantum theory of nonlinear electromagnetic response
Anwei Zhang, C. M. Wang
In recent years, the investigation of nonlinear electromagnetic responses has received significant attention due to its potential for elucidating the quantum properties of matter.…
Magneto-nonlinear Hall effect in time-reversal breaking system
Anwei Zhang, Jun-Won Rhim
Magneto-nonlinear Hall effect is known to be intrinsic and requires time-reversal symmetry. Here we show that a new type of magneto-nonlinear Hall effect can occur in the time-reve…
Geometric Origin of Intrinsic Spin Hall Effect in an Inhomogeneous Electric Field
Anwei Zhang, Jun-Won Rhim
In recent years, the spin Hall effect has received great attention because of its potential application in spintronics and quantum information processing and storage. However, this…
Relating the topology of Dirac Hamiltonians to quantum geometry: When the quantum metric dictates Chern numbers and winding numbers
Bruno Mera, Anwei Zhang, Nathan Goldman
Quantum geometry has emerged as a central and ubiquitous concept in quantum sciences, with direct consequences on quantum metrology and many-body quantum physics. In this context,…
