Trap** and manipulating ultracold atoms and degenerate quantum gases in magnetic
micropotentials is reviewed. Starting with a comprehensive description of the basic concepts …

We review the experimental realization of a single bosonic Josephson junction for ultracold
gases, which was made possible by the generation of a precisely controllable double-well …

Entanglement-enhanced quantum metrology explores the utilization of quantum
entanglement to enhance measurement precision. When particles in a probe are prepared …

We study the population dynamics of a Bose-Einstein condensate in a double-well potential
throughout the crossover from Josephson dynamics to hydrodynamics. At barriers higher …

We describe the controlled loading and measurement of number-squeezed states and
Poisson states of atoms in individual sites of a double well optical lattice. These states are …

We investigate the non-Abelian Josephson effect in F= 2 spinor Bose-Einstein condensates
with double optical traps. We propose a real physical system which contains non-Abelian …

We introduce a generic bosonic model exemplifying that (spin) Meissner currents can persist
in insulating phases of matter. We consider two species of interacting bosons on a lattice …

We introduce generic bosonic models exemplifying that chiral Meissner currents can persist
in insulating phases of matter. We first consider interacting bosons on a two-leg ladder. The …

We discuss the possibility of realizing a non-Hermitian, ie, an open two-well system of
ultracold atoms by enclosing it within additional time-dependent wells that serve as particle …

The designable integrability (DI)[51] of the variable coefficient nonlinear Schrödinger
equations (VCNLSEs) is first introduced by construction of an explicit transformation, which …
