Entanglement measures and non-equilibrium dynamics of quantum many-body systems: a path integral approach
Roopayan Ghosh, Nicolas Dupuis, Arnab Sen +1
We present a path integral formalism for expressing matrix elements of the density matrix of a quantum many-body system between any two coherent states in terms of standard Matsuba…
Scaling limit of soliton lengths in a multicolor box-ball system
Joel Lewis, Hanbaek Lyu, Pavlo Pylyavskyy +1
The box-ball systems are integrable cellular automata whose long-time behavior is characterized by soliton solutions, with rich connections to other integrable systems such as the…
Collapse and revival of quantum many-body scars via Floquet engineering
Bhaskar Mukherjee, Sourav Nandy, Arnab Sen +2
The presence of quantum scars, athermal eigenstates of a many-body Hamiltonian with finite energy density, leads to absence of ergodicity and long-time coherent dynamics in closed…
The dipolar spin glass transition in three dimensions
Tushar Kanti Bose, Roderich Moessner, Arnab Sen
Dilute dipolar Ising magnets remain a notoriously hard problem to tackle both analytically and numerically because of long-ranged interactions between spins as well as rare region…
Zero-temperature Glauber dynamics on the 3-regular tree and the median process
Michael Damron, Arnab Sen
In zero-temperature Glauber dynamics, vertices of a graph are given i.i.d.~initial spins from with , and they update their spins a…
