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 …

Spinor Bose gases form a family of quantum fluids manifesting both magnetic order and<?
format?> superfluidity. This article reviews experimental and theoretical progress in …

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

Dynamical quantum phase transitions are closely related to equilibrium quantum phase
transitions for ground states. Here, we report an experimental observation of a dynamical …

We have experimentally observed the dynamics of an antiferromagnetic sodium Bose-
Einstein condensate quenched through a quantum phase transition. Using an off-resonant …

A dynamical quantum phase transition can be characterized by a nonanalytic change in the
quench dynamics when a parameter in the governing Hamiltonian is varied. Such a …

Excited-state quantum phase transitions extend the notion of quantum phase transitions
beyond the ground state. They are characterized by closing energy gaps amid the spectrum …

We propose a method for engineering spin dynamics in ensembles of integer-spin atoms
confined within a high-finesse optical cavity. Our proposal uses cavity-assisted Raman …

We experimentally study spin dynamics in a sodium antiferromagnetic spinor condensate as
a result of spin-dependent interactions c and microwave dressing field interactions …

We propose a method to generate massive entanglement in a spinor Bose-Einstein
condensate from an initial product state through an adiabatic sweep of the magnetic field …
