Eigenstate Fluctuation Theorem in the Short and Long Time Regimes
Eiki Iyoda, Kazuya Kaneko, Takahiro Sagawa
The canonical ensemble plays a crucial role in statistical mechanics in and out of equilibrium. For example, the standard derivation of the fluctuation theorem relies on the assump…
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…
Work Extraction from a Single Energy Eigenstate
Kazuya Kaneko, Eiki Iyoda, Takahiro Sagawa
Work extraction from the Gibbs ensemble by a cyclic operation is impossible, as represented by the second law of thermodynamics. On the other hand, the eigenstate thermalization hy…
Effective dimension, level statistics, and integrability of Sachdev-Ye-Kitaev-like models
Eiki Iyoda, Hosho Katsura, Takahiro Sagawa
The Sachdev-Ye-Kitaev (SYK) model attracts attention in the context of information scrambling, which represents delocalization of quantum information and is quantified by the out-o…
