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 …

This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

Supersolids are states of matter that spontaneously break two continuous symmetries:
translational invariance owing to the appearance of a crystal structure and phase invariance …

Can a gas behave like a crystal? Supersolidity is an intriguing and challenging state of
matter that combines key features of superfluids and crystals. Predicted a long time ago, its …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

Reviews the history of optical trap** and manipulation of small-neutral particles, from the
time of its origin in 1970 up to the present. As we shall see, the unique characteristics of this …

Time crystals are a phase of matter, for which the discrete time symmetry of the driving
Hamiltonian is spontaneously broken. The breaking of discrete time symmetry has been …

We produce a quantum degenerate mixture composed by two Bose-Einstein condensates of
different atomic species, K 41 and R 87 b. We study the dynamics of the superfluid system in …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

The early experiments on Bose–Einstein condensation in dilute atomic gases accomplished
three long-standing goals. First, cooling of neutral atoms into their motional ground state …
