Asymptotic quantum many-body localization from thermal disorder

W De Roeck, F Huveneers - Communications in Mathematical Physics, 2014 - Springer
We consider a quantum lattice system with infinite-dimensional on-site Hilbert space, very
similar to the Bose–Hubbard model. We investigate many-body localization in this model …

Rapid mixing of path integral Monte Carlo for 1D stoquastic Hamiltonians

E Crosson, AW Harrow - Quantum, 2021 - quantum-journal.org
Abstract Path integral quantum Monte Carlo (PIMC) is a method for estimating thermal
equilibrium properties of stoquastic quantum spin systems by sampling from a classical …

Glauber dynamics for the quantum Ising model in a transverse field on a regular tree

F Martinelli, M Wouts - Journal of Statistical Physics, 2012 - Springer
Motivated by a recent use of Glauber dynamics for Monte Carlo simulations of path integral
representation of quantum spin models (Krzakala et al. in Phys. Rev. B 78 (13): 134428 …

Classical and Quantum Computation in Ground States and Beyond

E Crosson - 2015 - digital.lib.washington.edu
In this dissertation we study classical and quantum spin systems with applications to the
theory of computation. In particular, we examine computational aspects of these systems …
