WebOct 22, 2024 · In this work, we theoretically investigate basic properties of periodically-driven open quantum systems with the Maxwell–Bloch equation [ 51, 52 ], which may be the simplest model for driven open quantum systems, and provide an insight into the realization of Floquet states in such systems, addressing the following open questions: which kind of … WebOct 16, 2024 · A major goal of quantum condensed-matter physics is to control the electronic and atomic states of many particles. One of the most exciting emerging means for achieving such control is a periodic drive, such as a laser or time-varying magnetic field. putin\u0027s plan to attack japan

WebSep 1, 2024 · a Periodically driven unitary dynamics described by an operator U. While our nonintegrable system thermalizes for local observables at infinite times, we here discuss the phase transitions ... WebWe thus extend the notion of prethermal dynamics, observed in the high-frequency limit of periodically-driven systems, to a nonsymplectic setting. We analyze a new class of time-periodic dynamics in interacting chaotic classical spin systems, whose equations of motion are conservative (phase-space volume preserving) yet possess no symplectic ... WebThere has recently been much theoretical and experimental interest in quantum systems that are driven periodically in time, known as Floquet systems [1-2]. In these cases, fast oscillations can be used to alter the underlying band structure of the static (or time-averaged) system, generating exotic topological phases through a form of band ... putin\u0027s nukes
