Groupoids and Coherent States [PDF]

open access: yesOpen Systems & Information Dynamics, 2019
Schwinger’s algebra of selective measurements has a natural interpretation in terms of groupoids. This approach is pushed forward in this paper to show that the theory of coherent states has a natural setting in the framework of groupoids. Thus given a quantum mechanical system with associated Hilbert space determined by a representation of a groupoid,

Coherent full polarization control based on bound states in the continuum

open access: yesNature Communications, 2022
Bound states in the continuum (BICs) are resonant modes of open structures that do not suffer damping, despite being compatible with radiation in terms of their momentum.

Exact Coherent States and the Nonlinear Dynamics of Wall-Bounded Turbulent Flows

open access: yes, 2021
Wall-bounded turbulence exhibits patterns that persist in time and space: coherent structures. These are important for transport processes and form a conceptual framework for important theoretical ...

Entangled Coherent States in Teleportation

open access: yesEast European Journal of Physics, 2022
In the present paper, we will review the methods to produce superposition of entangled coherent state using polarizing beam splitter and Kerr non linearity.

Few-femtosecond resolved imaging of laser-driven nanoplasma expansion

open access: yesNew Journal of Physics, 2022
The free expansion of a planar plasma surface is a fundamental non-equilibrium process relevant for various fields but as-yet experimentally still difficult to capture.

Quantum secret sharing using weak coherent states [PDF]

open access: yesPhysical Review A, 2019
Secret sharing allows a trusted party (the dealer) to distribute a secret to a group of players, who can only access the secret cooperatively. Quantum secret sharing (QSS) protocols could provide unconditional security based on fundamental laws in ...

BPS coherent states and localization

open access: yesJournal of High Energy Physics, 2022
We introduce coherent states averaged over a gauge group action to study correlators of half BPS states in N $$ \mathcal{N} $$ = 4 SYM theory. The overlaps of these averaged coherent states are a generating function of correlators and can be written in ...

Generation and detection of non-Gaussian phonon-added coherent states in optomechanical systems [PDF]

open access: yesPhysical Review A, 2018
Adding excitations on a coherent state provides an effective way to observe the nonclassical properties of radiation fields. Here, we describe and analyze how to apply this concept to the motional state of a mechanical oscillator and present a full ...

Harvesting correlations from thermal and squeezed coherent states [PDF]

open access: yesPhysical Review D, 2018
We study the harvesting of entanglement and mutual information by Unruh-DeWitt particle detectors from thermal and squeezed coherent field states. We prove (for arbitrary spatial dimensions, switching profiles and detector smearings) that while the ...
