Breakdown of Markovianity by interactions in stroboscopic Floquet-Lindblad dynamics under high-frequency drive
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Floquet-Magnus (FM) expansion theory is a powerful tool in periodically driven (Floquet) systems under high-frequency drives. In closed systems, it dictates that their stroboscopic…
Exact Floquet quantum many-body scars under Rydberg blockade
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Quantum many-body scars have attracted much interest as a violation of the eigenstate thermalization hypothesis (ETH) due to recent experimental observation in Rydberg atoms and re…
Floquet engineering of topological phases protected by emergent symmetries under resonant drives
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Floquet engineering is one of the most vigorous fields in periodically driven (Floquet) systems, with which we can control phases of matter usually by high-frequency drives. In thi…
High-frequency Expansion for Floquet Prethermal Phases with Emergent Symmetries: Application to Time Crystals and Floquet Engineering
Kaoru Mizuta, Kazuaki Takasan, Norio Kawakami
Prethermalization, where quasi-steady states are realized in the intermediate long time regime (prethermal regime), in periodically driven (Floquet) systems is an important phenome…
Spatial-Translation-Induced Discrete Time Crystals
Kaoru Mizuta, Kazuaki Takasan, Masaya Nakagawa +1
A discrete time crystal is a phase unique to nonequilibrium systems, where discrete time translation symmetry is spontaneously broken. Most of conventional time crystals proposed s…
