Asymptotic evolution of bulk-viscous, spherically symmetric spacetimes

Balázs Endre Szigeti, Imre Ferenc Barna, Gergely Gábor Barnaföldi

The scale-free nature of gravitational interaction in both Newtonian gravity and the general theory of relativity gives rise to the concept of self-similarity, where solutions are…

Cylindrical Euler--Poisson Equation in a Chaplygin Gas Medium

Balázs Endre Szigeti, Imre Ferenc Barna, Gergely Gábor Barnaföldi

We studied the Euler--Poisson equation system in the case of cylindrical symmetry with the von Neumann--Sedov--Taylor type of self-similar Ansatz and present scaling solutions. We…

Can Rotation Solve the Hubble Puzzle?

Balázs Endre Szigeti, István Szapudi, Imre Ferenc Barna +1

The discrepancy between low and high redshift Hubble constant measurements is the highest significance tension within the concordance CDM paradigm. If not due to unknown s…

Analytical investigation of time-dependent two-dimensional non-Newtonian boundary layer equations

Imre F. Barna, G. Bognár, L. Mátyás +1

In this study, five different time-dependent incompressible non-Newtonian boundary layer models in two dimensions are investigated, including external magnetic field effects. The p…

Even and odd self-similar solutions of the diffusion equation for infinite horizon

L. Mátyás, I. F. Barna

In the description of transport phenomena an important aspect represents the diffusion. In certain cases the diffusion may appear together with convection. In this paper we study t…

Diatomic molecule in a strong infrared laser field: level-shifts and bond-length change due to laser-dressed Morse potential

Sándor Varró, Szabolcs Hack, Gábor Paragi +3

We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and fiel…
