Machine learning methods for Schlieren imaging of a plasma channel in tenuous atomic vapor
Gábor Bíró, Mihály Pocsai, Imre Ferenc Barna +2
We investigate the usage of a Schlieren imaging setup to measure the geometrical dimensions of a plasma channel in atomic vapor. Near resonant probe light is used to image the plas…
Time-dependent analytic solutions for water waves above sea of varying depths
I. F. Barna, M. A. Pocsai, L. Mátyás
We investigate a hydrodynamic equation system which - with some approximation - is capable to describe the tsunami propagation in the open ocean with the time-dependent self-simila…
Scaling Hydrodynamical Evolution of a Gravitating Dark-fluid Universe
Imre F. Barna, Mihály A. Pocsai, Gergely Gábor Barnaföldi
We present a dark fluid model which contains the general linear equation of state including the gravitation term. The obtained spherical symmetric Euler equation and the continuity…
Role of the laser chirp parameter in photoionisation
Mihály András Pocsai, Imre Ferenc Barna
Nowadays the development of novel particle accelerators is a hot topic for both experimental and theoretical sciences. In the CERN-AWAKE experiment electrons are accelerated in a c…
Self-similar analysis of a viscous heated Oberbeck-Boussinesq flow system
Imre Ferenc Barna, László Mátyás, Mihály András Pocsai
The simplest model to couple the heat conduction and Navier-Stokes equations together is the Oberbeck-Boussinesq(OB)system which were investigated by E.N. Lorenz and opened the par…
Interaction of antiproton with helium based on ab-initio calculations
Imre Ferenc Barna, Mihály András Pocsai, Károly Tőkési
We present ionization cross sections for antiproton and helium collisions based on ab-initio time-dependent coupled channel method. In our calculations a finite basis set of regula…
Photoionisation of Rubidium in strong laser fields
Mihály András Pocsai, Imre Ferenc Barna, Károly Tőkési
The photoionisation of rubidium in strong infra-red laser fields based on ab initio calculations was investigated. The bound and the continuum states are described with Slater orbi…
Self-similarity analysis of the non-linear Schrödinger equation in the Madelung form
Imre F. Barna, Mihály A. Pocsai, L. Mátyás
In the present study a particular case of Gross-Pitaevskii or non-linear Schrödinger equation is rewritten to a form similar to a hydrodynamic Euler equation using the Madelung tra…
The influence of a strong infrared radiation field on the conductance properties of doped semiconductors
I. F. Barna, M. A. Pocsai, S. Varró
This work presents an analytic angular differential cross section formula for the electromagnetic radiation field assisted electron scattering by %% was on impurities in semiconduc…
Analytic solutions of the Madelung equation
Imre F. Barna, Mihály A. Pocsai, László Mátyás
We present analytic self-similar solutions for the one, two and three dimensional Madelung hydrodynamical equation for a free particle. There is a direct connection between the zer…
Rayleigh-Bènard convection in the generalized Oberbeck-Boussinesq system
Imre Feren Barna, Mihály András Pocsai, Sándor Lökös +1
The original Oberbeck-Boussinesq (OB) equations which are the coupled two dimensional Navier-Stokes(NS) and heat conduction equations have been investigated by E.N. Lorenz half a c…
Electron Acceleration by a Bichromatic Chirped Laser Pulse in Underdense Plasmas
Mihály András Pocsai, Imre Ferenc Barna, Sándor Varró
A theoretical study of laser and plasma based electron acceleration is presented. An effective model has been used, in which the presence of an underdense plasma has been taken acc…
Electron Acceleration in Underdense Plasmas Described with a Classical Effective Theory
Mihály András Pocsai, Imre Ferenc Barna, Sándor Varró
An effective theory of laser--plasma based particle acceleration is presented. Here we treated the plasma as a continuous medium with an index of refraction in which a sing…
Theoretical Study of Steam Condensation Induced Water Hammer Phenomena in Horizontal Pipeline
Imre Ferenc Barna, Attila Rikard Imre
We investigate steam condensation induced water hammer (CIWH) phenomena and present new theoretical results. We use the WAHA3 model based on two-phase flow six first-order partial…
Pre-Excitation Studies for Rubidium-Plasma Generation
M. Aladi, J. S. Bakos, I. F. Barna +24
The key element in the Proton-Driven-Plasma-Wake-Field-Accelerator (AWAKE) project is the generation of highly uniform plasma from Rubidium vapor. The standard way to achieve full…
