Correspondence between Asymptotic Quantum Many-Body Scars in Closed Systems and Diffusive Nambu-Goldstone Modes in Open Systems
Masaya Kunimi, Taiki Haga, Masaya Nakagawa
Hydrodynamic relaxation in open quantum many-body systems can be understood in terms of diffusive Nambu--Goldstone (NG) modes associated with strong-to-weak spontaneous symmetry br…
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…
Liouvillian Skin Effect: Slowing Down of Relaxation Processes without Gap Closing
Taiki Haga, Masaya Nakagawa, Ryusuke Hamazaki +1
It is highly nontrivial to what extent we can deduce the relaxation behavior of a quantum dissipative system from the spectral gap of the Liouvillian that governs the time evolutio…
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…
Dimensional reduction and its breakdown in the driven random field O(N) model
Taiki Haga
The critical behavior of the random field model driven at a uniform velocity is investigated at zero-temperature. From naive phenomenological arguments, we introduce a dimen…
Nonequilibrium Kosterlitz-Thouless transition in a three-dimensional driven disordered system
Taiki Haga
We demonstrate a three-dimensional Kosterlitz-Thouless (KT) transition in the random field XY model driven out of thermal equilibrium. By employing the spin-wave approximation and…
Non-equilibrium quasi-long-range order of driven random field O(N) model
Taiki Haga
We investigate three-dimensional O(N) spin models driven with a uniform velocity over a random field. Within a spin-wave approximation, it is shown that in the strong driving regim…
Nonequilibrium Langevin equation and effective temperature for particle interacting with spatially extended environment
Taiki Haga
We investigate a novel type of Langevin model that describes the nonequilibrium dynamics of a classical particle interacting with a spatially extended environment. In this model, a…
