Laser-induced thermal source for cold atoms [PDF]
Scientific Reports, 2022 We demonstrate a simple and compact approach to laser cool and trap atoms based on laser-induced thermal ablation (LITA) of a pure solid granule. A rapid thermalisation of the granule leads to a fast recovery of the ultra-high vacuum condition required ...

Loading Dynamics of Cold Atoms into a Hollow-Core Photonic Crystal Fiber
Fibers, 2020 Cold atoms trapped and guided in hollow-core photonic crystal fibers provide a scalable diffraction-free setting for atom–light interactions for quantum technologies.

Momentum Halo in The Rayleigh Scattering by a Bose–Einstein Condensate
Atoms, 2022 A ring of radius ℏk0 in the momentum distribution of a Bose–Einstein condensate is visible when the atoms scatter a single photon. Here, we describe an approximated theory of this effect, leading to an analytic expression of the isotropic momentum ...

Vacuum pressure measurement of cold 7Li atoms in the magneto-optical and magnetic trap
AIP Advances, 2023 Cold atoms play a very important role in metrology. The ultra-high or extreme-high vacuum pressure can be accurately measured by investigating the collision of cold atoms and residual atoms in the environment. We report a vacuum pressure metrometer using

Classical and Quantum Collective Recoil Lasing: A Tutorial
Atoms, 2021 Collective atomic recoil lasing (CARL) is a process during which an ensemble of cold atoms, driven by a far-detuned laser beam, spontaneously organize themselves in periodic structures on the scale of the optical wavelength.

Multimode Collective Atomic Recoil Lasing in Free Space
Atoms, 2020 Cold atomic clouds in collective atomic recoil lasing are usually confined by an optical cavity, which forces the light-scattering to befall in the mode fixed by the resonator.

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
