We study entropy generation in a one-dimensional (1D) model of bosons in anoptical lattice experiencing two-particle losses. Such heating is a majorimpediment 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 1Dsetting. We also explore the time evolution of one and two particle correlationfunctions, showing that they are robust against two-particle loss. Because ofthis robustness, induced two-body losses can be used as a probe of short rangemagnetic correlations.
