Particle physics model of curvaton inflation in a stable universe
Zoltán Péli, István Nándori, Zoltán Trócsányi
We investigate a particle physics model for cosmic inflation based on the following assumptions: (i) there are at least two complex scalar fields; (ii) the scalar potential is boun…

Berezinskii-Kosterlitz-Thouless transition and criticality of an elliptic deformation of the sine-Gordon model
N. Defenu, V. Bacsó, I. G. Márián +2
We introduce and study the properties of a periodic model interpolating between the sine-- and the sinh--Gordon theories in dimensions. This model shows the peculiarities, du…

Nonperturbative renormalization group treatment of amplitude fluctuations for topological phase transitions
Nicolò Defenu, Andrea Trombettoni, István Nándori +1
The study of the Berezinskii-Kosterlitz-Thouless transition in two-dimensional models can be performed in several representations, and the amplitude-phase (AP) Madelung par…
