Emergence of surface long-range order under uniform shear flow
Hiroyoshi Nakano, Yuki Minami, Taiki Haga +1
We study the two-dimensional surface long-range order in a non-equilibrium steady state under shear flow using the three-dimensional conserved model. Whereas the correlation…
Effective temperature of a superfluid flowing in a random potential
Taiki Haga, Masahito Ueda
The spatial fluctuations of a superfluid flowing in a weak random potential are investigated. We employ classical field theory to demonstrate that the disorder-averaged nonequilibr…
Divergence of the Floquet-Magnus expansion in a periodically driven one-body system with energy localization
Taiki Haga
The Floquet-Magnus expansion is a useful tool to calculate an effective Hamiltonian for periodically driven systems. In this study, we investigate the convergence of the expansion…
Dimensional reduction in driven disordered systems
Taiki Haga
We investigate the critical behavior of disordered systems transversely driven at a uniform and steady velocity. An intuitive argument predicts that the long-distance physics of $D…
