Quantum coherence from commensurate driving with laser pulses and decay
Non-equilibrium physics is a particularly fascinating field of current research. Generically, driven systems are gradually heated up so that quantum effects die out. In contrast, we show that a driven central spin model including controlled dissipation in a highly excited state allows us to disti...

Non-equilibrium physics is a particularly fascinating field of current
research. Generically, driven systems are gradually heated up so that quantum
effects die out. In contrast, we show that a driven central spin model
including controlled dissipation in a highly excited state allows us to distill
quantum coherent states, indicated by a substantial reduction of entropy. The
model is experimentally accessible in quantum dots or molecules with unpaired
electrons. The potential of preparing and manipulating coherent states by
designed driving potentials is pointed out. |
