Time reversal and quantum Loschmidt echo in optical lattices
Time reversal and quantum Loschmidt echo in optical lattices
Schützhold, R.; Szpak, N.
A quantum Loschmidt echo (also referred to as quantum time mirror) corresponds to an effective time inversion after which the quantum wave function reverses its previous time evolution and eventually reaches its initial distribution again. We propose a comparably simple protocol for such an effective time reversal for ultra-cold atoms in optical lattices which should be easier to realize experimentally than previous proposals.
