Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Open system dynamics in constrained many-body systems
    (2022-08) Xiong, Bo
    In this dissertation, I investigate discuss constrained boundary Lindblad dynamics of the integrable, PXPand GOE systems coupled to a bath described by the PXP-type Hamiltonian. Two types of constraints are imposed on the system: (a) constrained Ising Hilbert space which is lack of a tensor product structure and (b) kinetic constraints imposed not only inside the systems but also at the boundary between the system and the bath. In all of the three systems, we observe a strong dependence of relaxation rates on the initial eigenstates. In particular, two types of slow states are observed and investigated. The impact of exponentially large zero energy space on the open-system dynamics is proved to be small.
