Cooling through optimal control of quantum evolution
Armin Rahmani, Takuya Kitagawa, Eugene Demler +1
Nonadiabatic unitary evolution with tailored time-dependent Hamiltonians can prepare systems of cold atomic gases with various desired properties. For a system of two one-dimension…

Optimal control for unitary preparation of many-body states: application to Luttinger liquids
Armin Rahmani, Claudio Chamon
Many-body ground states can be prepared via unitary evolution in cold atomic systems. Given the initial state and a fixed time for the evolution, how close can we get to a desired…
