Topological spin-orbit-coupled fermions beyond rotating wave approximation
Han Zhang, Wen-Wei Wang, Chang Qiao +6
The realization of spin-orbit-coupled ultracold gases has driven a wide range of researches and is typically based on the rotating wave approximation (RWA). By neglecting the count…
Spontaneous decay induced quantum dynamics in Rydberg blockaded Λ-type atoms
Chang Qiao, Wenxian Zhang
Strongly Rydberg-blockaded two-level atoms form a Rydberg superatom, which is excited only to a collective symmetrical Dicke state. However, emerging often in the alkali-earth atom…
Rydberg blockade in an ultracold strontium gas revealed by two-photon excitation dynamics
Chang Qiao, Can-Zhu Tan, Julia Siegl +5
We demonstrate the interaction-induced blockade effect in an ultracold Sr gas via studying the time dynamics of a two-photon excitation to the triplet Rydberg series $5\math…
Analyzing a single-laser repumping scheme for efficient loading of a strontium magneto-optical trap
Fachao Hu, Ingo Nosske, Luc Couturier +6
We demonstrate enhanced loading of strontium atoms into a magneto-optical trap using a repumping scheme from the metastable state via the doubly-excited state $5\mathrm{s}5\mathrm{…
Measurement of the strontium triplet Rydberg series by depletion spectroscopy of ultracold atoms
Luc Couturier, Ingo Nosske, Fachao Hu +5
We report on the atom loss spectroscopy of strontium Rydberg atoms in a magneto-optical trap, using a two-photon excitation scheme through the intermediate state $5\mathrm{s}5\math…
Laser frequency stabilization using a commercial wavelength meter
Luc Couturier, Ingo Nosske, Fachao Hu +5
We present the characterization of a laser frequency stabilization scheme using a state-of-the-art wavelength meter based on solid Fizeau interferometers. For a frequency-doubled T…
Two-dimensional magneto-optical trap as a source for cold strontium atoms
Ingo Nosske, Luc Couturier, Fachao Hu +6
We report on the realization of a transversely loaded two-dimensional magneto-optical trap serving as a source for cold strontium atoms. We analyze the dependence of the source's p…
