Two-body recombination in a quantum mechanical lattice gas: Entropy generation and probing of short-range magnetic correlations
arXiv:1003.5235 · doi:10.1103/PhysRevA.82.023626
Abstract
We study entropy generation in a one-dimensional (1D) model of bosons in an optical lattice experiencing two-particle losses. Such heating is a major impediment to observing exotic low temperature states, and "simulating" condensed matter systems. Developing intuition through numerical simulations, we present a simple empirical model for the entropy produced in this 1D setting. We also explore the time evolution of one and two particle correlation functions, showing that they are robust against two-particle loss. Because of this robustness, induced two-body losses can be used as a probe of short range magnetic correlations.
