Spontaneous symmetry breaking in non-steady modes of open quantum many-body systems
Taiki Haga
In a quantum many-body system coupled to the environment, its steady state can exhibit spontaneous symmetry breaking when a control parameter exceeds a critical value. In this stud…
Quasiparticles of Decoherence Processes in Open Quantum Many-Body Systems: Incoherentons
Taiki Haga, Masaya Nakagawa, Ryusuke Hamazaki +1
The relaxation dynamics of an open quantum system is determined by the competition between the coherent Hamiltonian dynamics of a system and the dissipative dynamics due to interac…
Lindbladian Many-Body Localization
Ryusuke Hamazaki, Masaya Nakagawa, Taiki Haga +1
We discover a novel localization transition that alters the dynamics of coherence in disordered many-body spin systems subject to Markovian dissipation. The transition occurs in th…
Interscale entanglement production in a quantum system simulating classical chaos
Taiki Haga, Shin-ichi Sasa
It is a fundamental problem how the universal concept of classical chaos emerges from the microscopic description of quantum mechanics. We here study standard classical chaos in a…
