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…
Crosscap Quenches and Entanglement Evolution
Zixia Wei, Yasushi Yoneta
Understanding the mechanisms by which complex correlations emerge through the dynamics of quantum many-body systems remains a fundamental challenge in modern physics. To address th…
Optimal statistical ensembles for quantum thermal state preparation within the quantum singular value transformation framework
Yasushi Yoneta
Preparing thermal equilibrium states is an essential task for finite-temperature quantum simulations. In statistical mechanics, microstates in thermal equilibrium can be obtained f…
Thermal Pure States for Systems with Antiunitary Symmetries and Their Tensor Network Representations
Yasushi Yoneta
Thermal pure state algorithms, which employ pure quantum states representing thermal equilibrium states instead of statistical ensembles, are useful both for numerical simulations…
