Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

We report on the experimental realization of a conservative optical lattice for cold atoms with
a subwavelength spatial structure. The potential is based on the nonlinear optical response …

Non-Hermitian skin effect (NHSE) describes a unique non-Hermitian phenomenon that all
eigen-modes are localized near the boundary, and has profound impact on a wide range of …

Quantum simulations with ultracold atoms typically create atomic wave functions with
structures at optical length scales, where direct imaging suffers from the diffraction limit. In …

Biphotons, generated from a hot atomic vapor via the process of spontaneous four-wave
mixing (SFWM), have the following merits: Stable and tunable frequencies as well as …

We propose and describe our realization of a deeply subwavelength optical lattice for
ultracold neutral atoms using N resonantly Raman-coupled internal degrees of freedom …

We propose and analyze a scanning microscope to monitor “live” the quantum dynamics of
cold atoms in a cavity QED setup. The microscope measures the atomic density with …

The recent experimental realization of a three-dimensional (3D) optical lattice clock not only
reduces the influence of collisional interactions on the clock's accuracy but also provides a …

Optical lattices are typically created via the ac Stark shift and are limited by diffraction to
periodicities≥ λ/2, where λ is the wavelength of light used to create them. Lattices with …

We systematically studied the temporal profile of biphotons, pairs of time-correlated single
photons, generated from a hot atomic vapor via the spontaneous four-wave mixing process …
