This review summarizes the recent progress toward the fabrication of surface patterns
depending on the monolayer colloidal crystal templates. Based on the structural differences …

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 …

We propose to use intensity correlation microscopy in combination with structured
illumination to image quantum emitters that exhibit antibunching with a spatial resolution …

A scheme is proposed for high-precision two-dimensional atom localization in a four-level
tripod-type atomic system via measurement of the excited state population. It is found that …

We discuss the generation of subwavelength optical barriers on the scale of tens of
nanometers, as conservative optical potentials for cold atoms. These arise from …

We present a proof-of-principle experiment in which the population of an atomic level is
spatially localized using the technique of electromagnetically induced transparency (EIT) …

The resolution limits of popular sub-diffraction and sub-wavelength imaging schemes are
examined using a unified approach that allows rapid comparison of the relative merits and …

We report an experiment in which an atomic excitation is localized to a spatial width that is a
factor<? format?> of 8 smaller than the wavelength of the incident light. The experiment …

Atomic correlations have been studied in physics for over 50 years and known as collective
effects until recently when they came to be recognized as a source of entanglement. This is …

We study the possibility of creating spatial patterns having subwavelength size by using the
so-called dark states formed by the interaction between atoms and optical fields. These …
