Hydrodynamics in long-range interacting systems with center-of-mass conservation
Alan Morningstar, Nicholas O'Dea, Jonas Richter
In systems with a conserved density, the additional conservation of the center of mass (dipole moment) has been shown to slow down the associated hydrodynamics. At the same time, l…
Many-body resonances in the avalanche instability of many-body localization
Hyunsoo Ha, Alan Morningstar, David A. Huse
Many-body localized (MBL) systems fail to reach thermal equilibrium under their own dynamics, even though they are interacting, nonintegrable, and in an extensively excited state.…
Entanglement and Absorbing-State Transitions in Interactive Quantum Dynamics
Nicholas O'Dea, Alan Morningstar, Sarang Gopalakrishnan +1
Nascent quantum computers motivate the exploration of quantum many-body systems in nontraditional scenarios. For example, it has become natural to explore the dynamics of systems e…
Universality classes of thermalization for mesoscopic Floquet systems
Alan Morningstar, David A. Huse, Vedika Khemani
We identify several phases of thermalization that describe regimes of behavior in isolated, periodically driven (Floquet), mesoscopic quantum chaotic systems. We also identify a ne…
Probing site-resolved correlations in a spin system of ultracold molecules
Lysander Christakis, Jason S. Rosenberg, Ravin Raj +5
Synthetic quantum systems with interacting constituents play an important role in quantum information processing and in elucidating fundamental phenomena in many-body physics. Foll…
Emergence of Fermi's Golden Rule
Tobias Micklitz, Alan Morningstar, Alexander Altland +1
Fermi's Golden Rule (FGR) applies in the limit where an initial quantum state is weakly coupled to a {\it continuum} of other final states overlapping its energy. Here we investiga…
Distinct universality classes of diffusive transport from full counting statistics
Sarang Gopalakrishnan, Alan Morningstar, Romain Vasseur +1
The hydrodynamic transport of local conserved densities furnishes an effective coarse-grained description of the dynamics of a many-body quantum system. However, the full quantum d…
Simulation of quantum physics with Tensor Processing Units: brute-force computation of ground states and time evolution
Markus Hauru, Alan Morningstar, Jackson Beall +3
Tensor Processing Units (TPUs) were developed by Google exclusively to support large-scale machine learning tasks. TPUs can, however, also be used to accelerate and scale up other…
Simulation of quantum many-body dynamics with Tensor Processing Units: Floquet prethermalization
Alan Morningstar, Markus Hauru, Jackson Beall +4
Tensor Processing Units (TPUs) are specialized hardware accelerators developed by Google to support large-scale machine-learning tasks, but they can also be leveraged to accelerate…
Avalanches and many-body resonances in many-body localized systems
Alan Morningstar, Luis Colmenarez, Vedika Khemani +2
We numerically study both the avalanche instability and many-body resonances in strongly-disordered spin chains exhibiting many-body localization (MBL). We distinguish between a fi…
Many-body localization near the critical point
Alan Morningstar, David A. Huse, John Z. Imbrie
We examine the many-body localization (MBL) phase transition in one-dimensional quantum systems with quenched randomness and short-range interactions. Following recent works, we us…
Kinetically constrained freezing transition in a dipole-conserving system
Alan Morningstar, Vedika Khemani, David A. Huse
We study a stochastic lattice gas of particles in one dimension with strictly finite-range interactions that respect the fracton-like conservation laws of total charge and dipole m…
Subdiffusion and heat transport in a tilted 2D Fermi-Hubbard system
Elmer Guardado-Sanchez, Alan Morningstar, Benjamin M. Spar +3
Using quantum gas microscopy we study the late-time effective hydrodynamics of an isolated cold-atom Fermi-Hubbard system subject to an external linear potential (a "tilt"). The ti…
Renormalization-group study of the many-body localization transition in one dimension
Alan Morningstar, David A. Huse
Using a new approximate strong-randomness renormalization group (RG), we study the many-body localized (MBL) phase and phase transition in one-dimensional quantum systems with shor…
