This is an introductory review of the physics of topological quantum matter with cold atoms.
Topological quantum phases, originally discovered and investigated in condensed matter …

As topologically stable objects in field theories, knots have been put forward to explain
various persistent phenomena in systems ranging from atoms and molecules to cosmic …

We construct optical beams in free space with robust skyrmionic structures in their
polarization fields, both in the electric spin vector for near-circular fields and in the …

Mutual friction caused by scattering of thermal excitations by quantized vortices is a
phenomenon of key importance for the understanding of vortex dynamics and quantum …

Typically, the chiral magnetic Skyrmion is a single-state excitation. Here we propose a
system, where multiplet of Skyrmion states appears and one of these states can be the …

We demonstrate coupling between the atomic spin-and orbital-angular momentum (OAM) of
the atom's center-of-mass motion in a Bose-Einstein condensate (BEC). The coupling is …

Classical electromagnetism and quantum mechanics are both central to the modern
understanding of the physical world and its ongoing technological development. Quantum …

The Kibble-Zurek mechanism provides a unified theory to describe the universal scaling
laws in the dynamics when a system is driven through a second-order quantum phase …

This article overviews topological excitations in spinor Bose–Einstein condensates of dilute
atomic gases. Various types of line defects, point defects and skyrmions are discussed. A …

We experimentally and numerically demonstrate deterministic creation and manipulation of
a pair of oppositely charged singly quantized vortices in a highly oblate Bose-Einstein …
