Role of Goldstone mode in nonequilibrium insulator under DC electric field
Xi Chen, Jong E. Han
Measurements of resistive breakdown in electronic systems under a DC electric field have shown that the threshold fields for the insulator-to-metal transition are significantly low…
Avalanche Instability as Nonequilibrium Quantum Criticality
Xi Chen, Jong E. Han
A fundamental instability in the nonequilibrium conduction band under a electric field bias is proposed via the spontaneous emission of coherent phonons. Analytic theory, supported…
Rashba spin-orbit coupling enhanced magnetoresistance in junctions with one ferromagnet
Chenghao Shen, Ranran Cai, Alex Matos-Abiague +3
We explain how Rashba spin-orbit coupling (SOC) in a two-dimensional electron gas (2DEG), or in a conventional -wave superconductor, can lead to a large magnetoresistance even w…
Electrically driven insulator-to-metal transition in a correlated insulator: Electronic mechanism and thermal description
Manuel I. Díaz, Jong E. Han, Camille Aron
Motivated by the resistive switchings in transition-metal oxides (TMOs) induced by a voltage bias, we study the far-from-equilibrium dynamics of an electric-field-driven strongly-c…
Fusion of Majorana Bound States with Mini-Gate Control in Two-Dimensional Systems
Tong Zhou, Matthieu C. Dartiailh, Kasra Sardashti +4
A hallmark of topological superconductivity is the non-Abelian statistics of Majorana bound states (MBS), its chargeless zero-energy emergent quasiparticles. The resulting fraction…
Resonant Tunneling Anisotropic Magnetoresistance Induced by Magnetic Proximity
Chenghao Shen, Timothy Leeney, Alex Matos-Abiague +3
We reveal that the interplay between Rashba spin-orbit coupling and proximity-induced magnetization in a two-dimensional electron gas leads to peculiar transport properties and lar…
Nonequilibrium Excitations and Transport of Dirac Electrons in Electric-Field-Driven Graphene
Jiajun Li, Jong E. Han
We investigate nonequilibrium excitations and charge transport in charge-neutral graphene driven with DC electric field by using the nonequilibrium Green's function technique. Due…
Energy dissipation in DC-field driven electron lattice coupled to fermion baths
Jong E. Han, Jiajun Li
Electron transport in electric-field-driven tight-binding lattice coupled to fermion baths is comprehensively studied. We reformulate the problem by using the scattering state meth…
Quantitative reliability of Migdal-Eliashberg theory for strong electron-phonon coupling
Johannes Bauer, Jong E. Han, Olle Gunnarsson
We reassess the validity of Migdal-Eliashberg (ME) theory for coupled electron-phonon systems for large couplings . Although model calculations have found that ME theory breaks…
Mapping of strongly correlated steady-state nonequilibrium to an effective equilibrium
J. E. Han
By mapping steady-state nonequilibrium to an effective equilibrium, we formulate nonequilibrium problems within an equilibrium picture where we can apply existing equilibrium many-…
