Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

The relaxation of isolated quantum many-body systems is a major unsolved problem
connecting statistical and quantum physics. Studying such relaxation processes remains a …

Quantum scrambling describes the spreading of information into many degrees of freedom
in quantum systems, such that the information is no longer accessible locally but becomes …

Quantum chaos refers to signatures of classical chaos found in the quantum domain.
Recently, it has become common to equate the exponential behavior of out-of-time order …

After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

The coupling of two macroscopic quantum states through a tunnel barrier gives rise to
Josephson phenomena such as Rabi oscillations, the ac and dc effects, or macroscopic self …

Entanglement is the key quantum resource for improving measurement sensitivity beyond
classical limits. However, the production of entanglement in mesoscopic atomic systems has …

Chirality is an asymmetric property widely found in nature. Here, we propose and
demonstrate experimentally the spontaneous emergence of chirality in an on-chip ultrahigh …

The phenomenon of Bose–Einstein condensation is a phase transition originally predicted
by Bose and Einstein in 1924. In particular, it was shown that below a critical temperature T …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …
