Coherence Freeze in an Optical Lattice Investigated Via Pump-Probe Spectroscopy
Coherence Freeze in an Optical Lattice Investigated Via Pump-Probe Spectroscopy
Motivated by our observation of fast echo decay and a surprising coherence freeze, we have developed a pump-probe spectroscopy technique for vibrational states of ultracold $^{85}$Rb atoms in an optical lattice to gain information about the memory dynamics of the system. We use pump-probe spectroscopy to monitor the time-dependent changes …
