Second law of thermodynamics in closed quantum many-body systems
Yuuya Chiba, Yasushi Yoneta, Ryusuke Hamazaki +1
The second law of thermodynamics for adiabatic operations -- constraints on state transitions in closed systems under external control -- is one of the fundamental principles of th…
Key Observable for Linear Thermalization
Yuuya Chiba, Akira Shimizu
For studies on thermalization of an isolated quantum many-body system, the fundamental issue is to determine whether a given system thermalizes or not. However, most studies tested…
Statistical ensembles for phase coexistence states specified by noncommutative additive observables
Yasushi Yoneta, Akira Shimizu
A phase coexistence state cannot be specified uniquely by any intensive parameters, such as the temperature and the magnetic field, because they take the same values over all coexi…
Robustness of equilibrium off-diagonal current fluctuation against localization of electron states in macroscopic two-dimensional systems
Kentaro Kubo, Kenichi Asano, Akira Shimizu
We study the off-diagonal current fluctuation in a macroscopic quantum system measured in an ideal manner that is as close as possible to the classical ideal measurement. We show r…
Thermal Pure Quantum Matrix Product States Recovering a Volume Law Entanglement
Atsushi Iwaki, Akira Shimizu, Chisa Hotta
We propose a way to construct a thermal pure quantum matrix product state (TPQ-MPS) that can simulate finite temperature quantum many-body systems with a minimal numerical cost com…
Anomalous Behavior of Magnetic Susceptibility Obtained by Quench Experiments in Isolated Quantum Systems
Yuuya Chiba, Kenichi Asano, Akira Shimizu
We examine how the magnetic susceptibility obtained by the quench experiment on isolated quantum systems is related to the isothermal and adiabatic susceptibilities defined in ther…
