Characterizing complexity of many-body quantum dynamics by higher-order eigenstate thermalization
Kazuya Kaneko, Eiki Iyoda, Takahiro Sagawa
Complexity of dynamics is at the core of quantum many-body chaos and exhibits a hierarchical feature: higher-order complexity implies more chaotic dynamics. Conventional ergodicity…
Universal scrambling in gapless quantum spin chains
Shunsuke Nakamura, Eiki Iyoda, Tetsuo Deguchi +1
Information scrambling, characterized by the out-of-time-ordered correlator (OTOC), has attracted much attention, as it sheds new light on chaotic dynamics in quantum many-body sys…
Heating and Cooling of Quantum Gas by Eigenstate Joule Expansion
Jae Dong Noh, Eiki Iyoda, Takahiro Sagawa
We investigate the Joule expansion of an interacting quantum gas in an energy eigenstate. The Joule expansion occurs when two subsystems of different particle density are allowed t…
Saturation of entropy production in quantum many-body systems
Kazuya Kaneko, Eiki Iyoda, Takahiro Sagawa
Bridging the second law of thermodynamics and microscopic reversible dynamics has been a longstanding problem in statistical physics. We here address this problem on the basis of q…
