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 …

In this report we discuss the dynamical response of heavy quantum impurities immersed in a
Fermi gas at zero and at finite temperature. Studying both the frequency and the time …

The fastest possible collective response of a quantum many-body system is related to its
excitations at the highest possible energy. In condensed matter systems, the time scale for …

Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary
excitations of a many-particle background. In the field of ultracold atoms, the study of the …

We propose an experimental scheme to verify the quantum nonequilibrium fluctuation
relations using current technology. Specifically, we show that the characteristic function of …

We propose an interferometric setting for the ancilla-assisted measurement of the
characteristic function of the work distribution following a time-dependent process …

The dynamical signatures of quantum chaos in an isolated system are captured by the
spectral form factor, which exhibits as a function of time a dip, a ramp, and a plateau, with the …

The recent experimental realization of strongly imbalanced mixtures of ultracold atoms
opens new possibilities for studying impurity dynamics in a controlled setting. In this paper …

We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

The precise measurement of low temperatures is a challenging, important, and fundamental
task for quantum science. In particular, in situ thermometry is highly desirable for cold atomic …
