Many-body quantum systems with a coherent time evolution are now experimentally realizable at various scales of size and durations. The behavior of such quantum matter holds many deep questions. One of these regards the stability of such systems, especially under when subjected to external drives. A branch of non-equilibrium physics, this is a vast and deep subject, harboring much unchartered territory.
Mechanisms of constraining the many-body dynamics in the Hilbert space range from highly debated and richly explored conundra like Many-body localization (MBL), to more recent ones like Floquet MBL, Dynamical Freezing, and Hilbert Space Fragmentation. These mechanisms can potentially underpin novel phases of quantum matter in and out of equilibrium.
Investigating these mechanisms is likely to draw heavily on the moving fronts of diverse disciplines like Condensed Matter Physics, Statistical Mechanics, Quantum Field Theory, and even frontline Mathematics. The aim of this program is to take stock of these fields, to summarize the state-of-art concepts and tools of these diverging fronts and focus the relevant ones towards understanding the manifold aspects of the many-body stability problem. More applied motivations include the need to devise stable modes of operation of various quantum devices which are around the corner, as well as extending our capacity to control quantum systems more generally, and the program would hence be relevant for researchers working on various fronts of quantum technologies.
Eligibility criteria: Senior PhD Students, Postdocs, and faculty members of Universities and Institutes. Alignment of their work/activities with the field will be a key criteria for the selection. One week of accommodation can at most be provided.
Accommodation will be provided for outstation participants at our on campus and IAS guest house.
