Coherent electron splitting in interacting chiral edge channels
Eiki Iyoda, Takase Shimizu, Masayuki Hashisaka
This paper theoretically studies the quantum coherence of an electronic state on an artificial chiral Tomonaga-Luttinger (TL) liquid. Coulomb interaction between copropagating inte…
Mach-Zehnder interference of fractionalized electron-spin excitations
Takase Shimizu, Eiki Iyoda, Satoshi Sasaki +4
Inter-channel Coulomb interaction mixes charge excitations in copropagating quantum Hall edge channels, generating coupled excitation eigenmodes propagating at different speeds. Th…
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…
