Quantum information processing based on Rydberg atoms emerged as a promising
direction two decades ago. Recent experimental and theoretical progresses have shined …

Coupling a quantum many-body system to an external environment dramatically changes its
dynamics and offers novel possibilities not found in closed systems. Of special interest are …

Interacting many-body systems display enhanced sensitivity close to critical transition points
due to diverging quantum fluctuations. This criticality-based enhancement has been …

We report the first observation of the magnon-polariton bistability in a cavity magnonics
system consisting of cavity photons strongly interacting with the magnons in a small yttrium …

In this article we provide a review of geometrical methods employed in the analysis of
quantum phase transitions and non-equilibrium dissipative phase transitions. After a …

Terahertz (THz) near-field imaging is a flourishing discipline 1, 2, with applications from
fundamental studies of beam propagation 3 to the characterization of metamaterials 4, 5 and …

By mapping the strong interaction between Rydberg excitations in ultra-cold atomic
ensembles onto single photons via electromagnetically induced transparency, it is now …

The strong interaction between individual Rydberg atoms provides a powerful tool exploited
in an ever-growing range of applications in quantum information science, quantum …

Higher-order and fractional discrete time crystals (DTCs) are exotic phases of matter where
the discrete time translation symmetry is broken into higher-order and non-integer category …

Quantum phase transitions are usually studied in terms of Hermitian Hamiltonians. However,
cold-atom experiments are intrinsically non-Hermitian because of spontaneous decay. Here …
