Prompt Photons at ATLAS

, 2012
A prompt photon is one which originates from the hard scatter or parton fragmentation. Studying the direct production of photons provides a means of testing predictions from next-to-leading order perturbative QCD calculations in kinematic regions never ...

Birefringence and hidden photons

, 2018
We study a model where photons interact with hidden photons and millicharged particles through a kinetic mixing term. Particularly, we focus on vacuum birefringence effects and we find a bound for the millicharged parameter assuming that hidden photons ...

The refractive index of a single three-level atom experienced by a single photon

Frontiers in Quantum Science and Technology
We study the propagation of a quantum field composed of a few photons interacting with a three-level Λ-atom driven by a coherent classical field. The quantum field acquires a phase shift, which can be interpreted as a dispersion effect on the photon wave

Photons indiscernables : qui se ressemble, s'assemble

, 2006
Les boîtes quantiques semi-conductrices sont des candidats prometteurs pour la génération d'états quantiques de la lumière, tels que des photons uniques. En isolant ces nano-émetteurs dans des microcavités optiques, ces émetteurs uniques peuvent produire

Heralded generation of entanglement with photons

Entangled states of photons form the backbone of many quantum technologies. Due to the lack of effective photon–photon interactions, the generation of these states is typically probabilistic.

Canonical vs. Grand Canonical Ensemble for Bosonic Gases under Harmonic Confinement

Entropy
We analyze the general relation between canonical and grand canonical ensembles in the thermodynamic limit. We begin our discussion by deriving, with an alternative approach, some standard results first obtained by Kac and coworkers in the late 1970s ...
