We show that induced dipole-dipole interactions allow for photon blockade in
subwavelength ensembles of two-level, ground-state neutral atoms. Our protocol relies on …

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 investigate two-color photon correlations in the light emitted by two strongly driven,
strongly interacting two-level emitters. The correlations are interpreted introducing the …

Bright solitons in atomic Bose-Einstein condensates are strong candidates for high precision
matter-wave interferometry, as their inherent stability against dispersion supports long …

There has been a recent surge of interest and progress in creating subwavelength free-
space optical potentials for ultracold atoms. A key open question is whether geometric …

Optical potentials have been a versatile tool for the study of atomic motions and many-body
interactions in cold atoms. Recently, optical subwavelength single barriers were proposed to …

Transport experiments are among the most important methods to probe and characterize
strongly interacting fermionic systems and the myriad states of matter that exist therein. The …

We report on a structural superfluid–Mott-insulator (SF-MI) quantum phase transition for an
interacting one-dimensional Bose gas within permeable multirod lattices, where the rod …

Cold atoms trapped in optical lattices have been proven to be a versatile, well-controlled
and powerful platform for simulating and studying physics, from condensed matter systems …

In this work we study the photon blockade and antiblockade effects in a system of neutral
atoms with a two-level structure, in the limit where induced dipole-dipole interactions …
