Intrinsic Heating and Cooling in Adiabatic Processes for Bosons in Optical Lattices
Intrinsic Heating and Cooling in Adiabatic Processes for Bosons in Optical Lattices
We show that by raising the lattice "adiabatically" as in all current optical lattice experiments on bosons, even though the temperature may decrease initially, it will eventually rise linearly with lattice height, taking the system further away from quantum degeneracy. This increase is {\rm intrinsic} and is caused by the …
