Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

Few‐Photon Fluorescence From Ultracold Bosons in an Optical Cavity

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second‐harmonic generation (SHG) regimes. Two settings are considered: (i) (few) bosons in an optical lattice and (ii) a trapped two‐component dilute Bose–Einstein condensate (2BEC) within the Bogoliubov scheme.

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

open access: yesJournal of Raman Spectroscopy, EarlyView.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

Quantization of Polaritons Confined in Dielectric Structures

open access: yesLaser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

THE BOSONIC STRUCTURE OF FERMIONS [PDF]

open access: yesModern Physics Letters A, 1994
We bosonize fermions by identifying their occupation numbers as the binary digits of a Bose occupation number. Unlike other schemes, our method allows infinitely many fermionic oscillators to be constructed from just one bosonic oscillator.

Upgrade des CMS‐Detektors für die Hochratenphase des LHC: Die Runderneuerung von CMS

open access: yesPhysik in unserer Zeit, EarlyView.
Ab 2030 wird der LHC in der Hochratenphase laufen. Die erheblich gesteigerte Proton‐Proton‐Kollisionsrate erfordert ein grundlegendes Update der beiden großen Detektoren ATLAS und CMS, dessen Runderneuerung hier vorgestellt wird. Zusammenfassung Ab 2030 soll der Large Hadron Collider (LHC) am CERN in der Hochratenphase (High Luminosity, High‐Lumi ...
