The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

Thermodynamics of quantum systems and quantum thermal machines are rapidly
developing fields, which have already delivered several promising results, as well as raised …

We investigate the collective decay dynamics of atoms with a generic multilevel structure
(angular momenta F↔ F′) coupled to two light modes of different polarization inside a …

Ultracold atomic systems are among the most promising platforms that have the potential to
shed light on the complex behavior of many-body quantum systems. One prominent …

Entanglement constitutes a main feature that distinguishes quantum from classical physics.
Here, however, we show that entanglement may also serve as the essential ingredient for …

Magnesium (Mg) is a metal having a high structural efficiency and a very high chemical
reactivity at the same time. Its potential areas of applications include the automotive industry …

Spin squeezing is one of the most attractive methods for realizing high-precision metrology.
In this paper we propose a protocol for generating spin squeezing in an atomic ensemble …

We present an analytical approach for the study of driven Dicke superradiance based on a
Heisenberg-Langevin formulation. We calculate the steady-state fluctuations of both the …

We investigate the fate of dissipative phase transitions in quantum many-body systems
when the individual constituents are qudits (d-level systems) instead of qubits. As an …

We study a many-atom system exhibiting two competing collective processes: collective
decay and collective pumping of excitations, relevant eg in cavity QED platforms. We find …
