The bilinear-biquadratic model on the complete graph
Dávid Jakab, Gergely Szirmai, Zoltán Zimborás
We study the spin-1 bilinear-biquadratic model on the complete graph of N sites, i.e., when each spin is interacting with every other spin with the same strength. Because of its co…

Renormalization group approach to the spin-1 Bose gas
Gergely Szirmai
A field theoretical renormalization group approach at two loop level is applied to the homogeneous spin-1 Bose gas in order to investigate the order of the phase transition. The be…

Properties of excitations in systems with a spinor Bose-Einstein condensate
Peter Szepfalusy, Gergely Szirmai
General theory in case of homogenous Bose-Einstein condensed systems with spinor condensate is presented for the correlation functions of density and spin fluctuations and for the…
