Critical states of transient chaos
Z. Kaufmann, A. Németh, P. Szépfalusy
One-dimensional maps exhibiting transient chaos and defined on two preimages of the unit interval [0,1] are investigated. It is shown that such maps have continuously many conditio…
Finite temperature excitations of Bose gases in anisotropic traps
J. Reidl, A. Csordás, R. Graham +1
The mode frequencies of a weakly interacting Bose gas in a magnetic trap are studied as a function of the anisotropy of the trap. As in earlier works the generalized Hartree-Fock-B…
Dielectric formalism and damping of collective modes in trapped Bose-Einstein condensed gases
Gy. Bene, P. Szepfalusy
We present the general dielectric formalism for Bose-Einstein condensed systems in external potential at finite temperatures. On the basis of a model arising within this framework…
Classical quasi-particle dynamics in trapped Bose condensates
Martin Fliesser, András Csordás, Robert Graham +1
The dynamics of quasi-particles in repulsive Bose condensates in a harmonic trap is studied in the classical limit. In isotropic traps the classical motion is integrable and separa…
Diffusion in normal and critical transient chaos
Z. Kaufmann, H. Lustfeld, A. Nemeth +1
In this paper we investigate deterministic diffusion in systems which are spatially extended in certain directions but are restricted in size and open in other directions, conseque…
