When adiabatic preparation is insufficient, it is natural to use some of the system’s own degrees of freedom as a bath, shifting entropy into a subregion of the trap. In general, correctly tuning the parameters of the “bath” requires a detailed understanding of the thermodynamics. I will discuss the feasibility of a scheme which is thermodynamically guaranteed to shift entropy elsewhere: decreasing the magnitude of the effective Hamiltonian in a sub-region. In addition to a detailed study of the thermodynamics and dynamics of this proposal, I will discuss how such cooling could be achieved for trapped polar molecules and the half-filled fermionic Hubbard model.
