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…
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…
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…
Fluctuation Theorem for Many-Body Pure Quantum States
Eiki Iyoda, Kazuya Kaneko, Takahiro Sagawa
We prove the second law of thermodynamics and the nonequilibirum fluctuation theorem for pure quantum states.The entire system obeys reversible unitary dynamics, where the initial…
