Free electron gas in cavity quantum electrodynamics

open access: yesPhysical Review Research, 2022
Cavity modification of material properties and phenomena is a novel research field largely motivated by the advances in strong light-matter interactions. Despite this progress, exact solutions for extended systems strongly coupled to the photon field are

Gross-Pitaevskii Limit of a Homogeneous Bose Gas at Positive Temperature [PDF]

open access: yes, 2020
We consider a dilute, homogeneous Bose gas at positive temperature. The system is investigated in the Gross-Pitaevskii (GP) limit, where the scattering length $a$ is so small that the interaction energy is of the same order of magnitude as the spectral ...

The properties of Tonk-Girardeau Gas at Finite Temperature and Comparison with Polarized Free Fermions

open access: yes, 2015
In the present paper we investigate the Tonks-Girardeau gas confined in a harmonic trap at finite temperature with thermal Bose-Fermi mapping method. The pair distribution, density distribution, reduced one-body density matrix, the occupations number of ...

Control of the geomorphology and gas hydrate extent on widespread gas emissions offshore Romania

open access: yesBSGF - Earth Sciences Bulletin, 2017
The Romanian sector of the Black Sea deserves attention because the Danube deep-sea fan is one of the largest sediment depositional systems worldwide and is considered the world's most isolated sea, the largest anoxic water body on the planet and a ...

Geological characteristics and resource potential of deep coalbed methane in Guizhou

open access: yesMeitan xuebao
Accelerating the exploration and development of deep ( > 1 000 m)coalbed methane (CBM) resources is an important way for the large-scale development of CBM and an important development direction in recent years. Guizhou Province is rich in CBM resources,
