Quantum control of population transfer between vibrational states in an optical lattice
Matin Hallaji, Chao Zhuang, Alex Hayat +4
We study quantum control techniques, specifically Adiabatic Rapid Passage (ARP) and Gradient Ascent Pulse Engineering (GRAPE), for transferring atoms trapped in an optical lattice…
Observation of EIT-enhanced cross-phase modulation in the short-pulse regime
Greg Dmochowski, Amir Feizpour, Matin Hallaji +3
We present an experiment using a sample of laser-cooled Rb atoms to show that cross-phase modulation schemes continue to benefit from electromagnetically-induced transparency (EIT)…
Observing the Onset of Effective Mass
Rockson Chang, Shreyas Potnis, Ramon Ramos +6
The response of a particle in a periodic potential to an applied force is commonly described by an effective mass which accounts for the detailed interaction between the particle a…
Coherent control of population transfer between vibrational states in an optical lattice via two-path quantum interference
Chao Zhuang, Christopher R. Paul, Xiaoxian Liu +3
We demonstrate coherent control of population transfer between vibrational states in an optical lattice by using interference between a one-phonon transition at and a two-phon…
Coherence freeze in an optical lattice investigated via pump-probe spectroscopy
Samansa Maneshi, Chao Zhuang, Christopher R. Paul +2
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 …
Efficient vibrational state coupling in an optical tilted-washboard potential via multiple spatial translations and application to pulse echo
Samansa Maneshi, Jalani F. Kanem, Chao Zhuang +2
We measure the application of simple and compound pulses consisting of time-dependent spatial translations to coupling vibrational states of ultracold 85Rb atoms in a far-detuned 1…
