Exciton-polaritons are light-matter mixed states interacting via their exciton fraction. They
can be excited, manipulated and detected using all the versatile techniques of modern …

We demonstrate confinement of Rb 85 atoms in a dark, toroidal optical trap. We use a spatial
light modulator to convert a single blue-detuned Gaussian laser beam to a superposition of …

Three-dimensional entanglement of orbital angular momentum states of an atomic qutrit and
a single photon qutrit has been observed. Their full state was reconstructed using quantum …

Observations of quantized vortices in dilute-gas Bose-Einstein condensates were first
reported in 1999. Over the next 10 years, more than 70 papers describing experiments …

In this study, for the first time, a theoretical investigation is carried out on the persistent orbital
charge-currents (cc) and induced magnetic field (imf) of Li and Na atom compressed by …

The advent of increasingly precise gyroscopes has played a key role in the technological
development of navigation systems. Ring-laser and fiber-optic gyroscopes, for example, are …

We study the dynamics of bright solitons formed in a Bose-Einstein condensate with
attractive atomic interactions perturbed by a weak bichromatic optical lattice potential. The …

Matter–wave interferometers are, in principle, orders of magnitude more sensitive than their
optical counterparts. Nevertheless, creation of matter–wave currents to achieve such a …

In this work we propose to study an atom confined in a potential which consists of a Hulthén
potential plus a ring-shaped potential. The atom is further subjected to a spherical …

A Bose-Einstein condensate in an oscillating spatially asymmetric potential is shown to
exhibit a directed current for unbiased initial conditions despite time symmetry. This …
