Fermion condensation under rotation on anti-de Sitter space
Victor E. Ambrus
Due to the local curvature, the fermion condensate (FC) for a free Dirac field on anti-de Sitter (adS) space becomes finite, even in the massless limit. Employing the point splitti…
Helical massive fermions under rotation
Victor E. Ambrus
The properties of a massive fermion field undergoing rigid rotation at finite temperature and chemical potential are discussed. The polarisation imbalance is taken into account by…
Implicit-Explicit Finite-Difference Lattice Boltzmann Model with Varying Adiabatic Index
Stefan T. Kis, Victor E. Ambrus
The perfect fluid limit can be obtained from the Boltzmann equation in the limit of vanishing Knudsen number. By treating the collision term in an implicit manner, the implicit-exp…
Comparison of the Shakhov and ellipsoidal models for the Boltzmann equation and DSMC for ab initio-based particle interactions
Victor E. Ambrus, Felix Sharipov, Victor Sofonea
In this paper, we consider the capabilities of the Boltzmann equation with the Shakhov and ellipsoidal models for the collision term to capture the characteristics of rarefied gas…
Multicomponent Flow on Curved Surfaces: A Vielbein Lattice Boltzmann Approach
Victor E. Ambruş, Sergiu Busuioc, Alexander J. Wagner +2
We develop and implement a novel lattice Boltzmann scheme to study multicomponent flows on curved surfaces, coupling the continuity and Navier-Stokes equations with the Cahn-Hillia…
Comparison between isothermal collision-streaming and finite-difference lattice Boltzmann models
Giuseppe Negro, Sergiu Busuioc, Victor E. Ambrus +3
We present here a comparison between collision-streaming and finite-difference lattice Boltzmann (LB) models. This study provides a derivation of useful formulae which help one to…
