Nonequilibrium Quasiparticle Effects on Domain Wall Dynamics in Superconductors
Takuma Kanakubo, Taira Kawamura, Yusuke Kato
We study the dynamics of a domain wall (DW) in a type-II superconductor connected to two heat reservoirs. We employ a generalized time-dependent Ginzburg--Landau framework in which…

Time-local nonequilibrium Green's function method for real-time dynamics in quantum systems coupled to superconducting leads
Taira Kawamura
We develop a time-local nonequilibrium Green's function formulation for real-time dynamics in quantum systems coupled to superconducting leads. The superconducting lead self-energy…

Emergence of Charge-Imbalanced BCS State and Suppression of Nonequilibrium FFLO State in Asymmetric NSN Junctions
Taira Kawamura, Yoji Ohashi
We theoretically study nonequilibrium superconductivity in voltage-biased normal metal-superconductor-normal metal (NSN) junctions, focusing on effects of lead-coupling asymmetry a…
