Collisionless Dynamics in Two-Dimensional Bosonic Gases

, 2018
We study the dynamics of dilute and ultracold bosonic gases in a quasi two-dimensional (2D) configuration and in the collisionless regime. We adopt the 2D Landau-Vlasov equation to describe a three-dimensional gas under very strong harmonic confinement ...

Bernstein–Greene–Kruskal and Case–Van Kampen Modes for the Landau–Vlasov Equation

Atoms, 2022
The one-dimensional Landau–Vlasov equation describing ultracold dilute bosonic gases in the mean-field collisionless regime under strong transverse confinement is analyzed using traditional methods of plasma physics.

Zero-temperature equation of state of mass-imbalanced resonant Fermi gases [PDF]

, 2014
We calculate the zero-temperature equation of state of mass-imbalanced resonant Fermi gases in an ab initio fashion, by implementing the recent proposal of imaginary-valued mass difference to bypass the sign problem in lattice Monte Carlo calculations ...

A Machine Learning-Based Platform for Monitoring and Prediction of Hazardous Gases in Rural and Remote Areas

IEEE Access
The emissions of pollutants and radioactive gases are the main causes of several environmental disasters that may cause premature deaths. The significant impact of these gases on public health is a major concern, especially in remote and rural regions ...

Real-Time odor classification through sequential bayesian filtering [PDF]

, 2015
The classification of volatiles substances with an e-nose is still a challenging problem, particularly when working under real-time, out-of-the-lab environmental conditions where the chaotic and highly dynamic characteristics of the gas transportation ...

Kinetic models with randomly perturbed binary collisions

, 2010
We introduce a class of Kac-like kinetic equations on the real line, with general random collisional rules, which include as particular cases models for wealth redistribution in an agent-based market or models for granular gases with a background heat ...

Propulsion and Thermodynamic Parameters of van der Waals Gases in Rocket Nozzles

International Journal of Aerospace Engineering, 2019
Propellants or combustion products can reach high pressures and temperatures in advanced or conventional propulsion systems. Variations in flow properties and the effects of real gases along a nozzle can become significant and influence the calculation ...

Pumped Transfer of Liquefied Gases

CHIMIA, 2004
The transfer of liquefied gases comprises a special hazard potential. Therefore special equipment and expertise is necessary. It is not possible for every HazMat base to hold its own equipment.

Prototype edge-grown nanowire sensor array for the real-time monitoring and classification of multiple gases

Journal of Science: Advanced Materials and Devices, 2020
The monitoring and classification of different gases using a single resistive semiconductor sensor are challenging because of the similar response characteristics.

Frictional drag between non-equilibrium charged gases

, 2000
The frictional drag force between separated but coupled two-dimensional electron gases of different temperatures is studied using the non-equilibrium Green function method based on the separation of center-of-mass and relative dynamics of electrons.
