We report recent progress on the phase space formulation of quantum mechanics with
coordinate‐momentum variables, focusing more on new theory of (weighted) constraint …

This is a text on quantum mechanics formulated simultaneously in terms of position and
momentum, ie in phase space. It is written at an introductory level, drawing on the …

Interfaces of light and matter serve as a platform for exciting many-body physics and
photonic quantum technologies. Due to the recent experimental realization of atomic arrays …

In recent experiments, a novel type of cascaded quantum system has been realized using
nanofiber-coupled cold atomic ensembles. This setup has enabled the study of superradiant …

We investigate the sub-Planck-scale structures associated with the SU (1, 1) group by
establishing that the Planck scale on the hyperbolic plane can be considered as the inverse …

We compare the entire classical and quantum evolutions of the Dicke model in its regular
and chaotic domains. This is a paradigmatic interacting spin-boson model of great …

The persistent separability of certain quantum states, known as symmetric absolutely
separable (SAS), under symmetry-preserving global unitary transformations is of key …

Continuous phase spaces have become a powerful tool for describing, analyzing, and
tomographically reconstructing quantum states in quantum optics and beyond. A plethora of …

A method for constructing all admissible unitary non-equivalent Wigner quasiprobability
distributions providing the Stratonovic-h-Weyl correspondence for an arbitrary N-level …

Coherent-state superpositions are of great importance for many quantum subjects, ranging
from foundational to technological, eg, from tests of collapse models to quantum metrology …
