Nonlinear Hall effect in topological Dirac semimetals in parallel magnetic field
Maxim Dzero, Maxim Khodas, Alex Levchenko +1
We compute the second-harmonic response of two-dimensional topological Dirac semimetals subjected to an external in-plane magnetic field. The quantum kinetic equation for the Wigne…
Spatially resolved collective modes in d-wave superconductors
Kazi Ranjibul Islam, Samuel Awelewa, Andrey V. Chubukov +1
We analyze the dispersion of collective modes in a superconductor with wave symmetry of the order parameter in the presence of long-range Coulomb interaction. We use diagrammat…
Dynamics of the Schmid-Higgs Mode in -wave superconductors
Samuel Awelewa, Maxim Dzero
We study the dynamics of the longitudinal collective mode in an unconventional superconductor. For concreteness, we assume that the superconductor is described by a -wave order…
Magnetic Field Induced Nonlinear Transport in LaTiO/SrTiO Interfaces
Aidan Steineman, Maxim Khodas, Maxim Dzero
Motivated by the recent experimental measurements of the nonlinear longitudinal resistance of the spin-orbit coupled electron gas in the (111) LaTiO/SrTiO interfaces under…
Resonant second harmonic generation in a two-dimensional electron system
Maxim Dzero, Jaglul Hasan, Alex Levchenko
We consider the nonlinear response of a disordered two-dimensional electronic system, lacking inversion symmetry, to an external alternating electric field. The application of an i…
Schmid-Higgs Mode in the Presence of Pair-Breaking Interactions
Maxim Dzero, Alex Kamenev
Collective modes in superconductors provided the first realization of the Higgs mechanism. The transverse Goldstone mode acquires a gap (i.e. a mass) when it hybridizes with the el…
