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…

Quantum-geometric origin of superfluid weight in quasicrystals with critical states
Kazuma Saito, Ryo Okugawa, Yusuke Kato +1
A distinctive feature of many quasiperiodic systems is the presence of critical states that are neither extended nor exponentially localized. We investigate the geometric effect on…

Dynamics of Topological Defects in Type-II Superconductors under Gradients of Temperature/Spin Density
Takuma Kanakubo, Hiroto Adachi, Masanori Ichioka +1
We theoretically investigate the motion of a domain wall and a vortex in type-II superconductors driven by inhomogeneities of temperature or spin accumulation. The model consists o…
