Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

In most cosmological models, rapid expansion of space marks the first moments of the
Universe and leads to the amplification of quantum fluctuations. The description of …

Over the past decade, there has been remarkable progress in our understanding of
equilibration, thermalization and prethermalization, due in large part to experimental …

Most experimental observations of solitons are limited to one-dimensional (1D) situations,
where they are naturally stable. For instance, in 1D cold Bose gases, they exist for any …

The bulk–boundary correspondence, a fundamental principle relating the topological
invariants of the bulk to the presence of edge states, is modified in periodically driven …

Optical box traps offer new possibilities for quantum-gas experiments. Building on their
exquisite spatial and temporal control, we propose to engineer system-reservoir …

Realizing strongly correlated topological phases of ultracold gases is a central goal for
ongoing experiments. While fractional quantum Hall states could soon be implemented in …

Though the celebrated spin echoes have been widely used to reverse quantum dynamics,
they are not applicable to systems whose constituents are beyond the control of the su (2) …

Since the discovery of crispations on a vibrating fluid layer, numerous types of patterns
formed on fluid surfaces have been revealed. Here we report the observation of polygonal …
