Stochastic Series Expansion Quantum Monte Carlo for Rydberg Arrays

  title={Stochastic Series Expansion Quantum Monte Carlo for Rydberg Arrays},
  author={Ejaaz Merali and Isaac J.S. De Vlugt and Roger G. Melko},
Arrays of Rydberg atoms are a powerful platform to realize strongly-interacting quantum many-body systems. A common Rydberg Hamiltonian is free of the sign problem, meaning that its equilibrium properties are amenable to efficient simulation by quantum Monte Carlo (QMC). In this paper, we develop a Stochastic Series Expansion QMC algorithm for Rydberg atoms interacting on arbitrary lattices. We describe a cluster update that allows for the efficient sampling and calculation of physical… Expand
