Many-body quantum chaos in stroboscopically-driven cold atoms
Communications Physics, 2023 In quantum chaotic systems, the spectral form factor (SFF), defined as the Fourier transform of two-level spectral correlation function, is known to follow random matrix theory (RMT), namely a ‘ramp’ followed by a ‘plateau’ in late times.

Superfluids, Fluctuations and Disorder
Applied Sciences, 2019 We present a field-theory description of ultracold bosonic atoms in the presence of a disordered external potential. By means of functional integration techniques, we aim to investigate and review the interplay between disordered energy landscapes and ...

Electric Field Excitation Suppression in Cold Atoms
Atoms, 2020 In this article, the atom excitation suppression is studied in two mechanisms. The first mechanism for excitation suppression is caused by an external DC electric field.

Observation of spin-space quantum transport induced by an atomic quantum point contact
Nature Communications, 2021 Cold atoms have recently become a versatile platform for the study of quantum transport phenomena. Here the authors realize an alternative experimental scheme for quantum transport with cold atoms, by using spin-dependent impurity scattering in a spinful

Direct loading of Yb atoms into a 3D magneto-optical trap from a dispenser atomic source
AIP Advances, 2023 The realization of cold atoms using a compact and low-power-consumption experimental setup is indispensable for cold atom experiments, including optical clocks and quantum simulations.

Cold-atom optical filtering enhanced by optical pumping
Frontiers in Physics, 2022 Atomic optical filters such as Faraday anomalous dispersion optical filters (FADOFs) or similar technologies can achieve very narrow optical bandwidth close to the scale of atomic linewidth, which can be greatly reduced in cold atoms. However, limited by

Exotic Superfluidity in Cold Atoms [PDF]
Crossing the Boundaries, 2010 We derived the low energy effective action for the collective modes in asymmetric fermionic systems with attractive interaction. We obtained the phase diagram in terms of the chemical potentials. It features a stable gapless superfluidity with one Fermi surface on the BEC side of the resonance.
