Magneto-optical trap reaction microscope for photoionization of cold strontium atoms
Shushu Ruan, Xinglong Yu, Zhenjie Shen +10
We developed a magneto-optical trap reaction microscope (MOTREMI) for strontium atoms by combining the multi-particle coincident detection with laser cooling technique. Present com…
Dynamics of position disordered Ising spins with a soft-core potential
Canzhu Tan, Xiaodong Lin, Yabing Zhou +3
We theoretically study magnetization relaxation of Ising spins distributed randomly in a -dimension homogeneous and Gaussian profile under a soft-core two-body interaction poten…
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…
Observation of photon recoil effects in single-beam absorption spectroscopy with an ultracold strontium gas
Fachao Hu, Canzhu Tan, Yuhai Jiang +2
We report on observing photon recoil effects in the absorption of a single monochromatic light at 689~nm through an ultracold Sr gas, where the recoil frequency is comparabl…
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…
