Thermodynamics of the pion gas using the O(N) model in 1/N expansion
Tomas Brauner
We investigate the thermodynamics of a pion gas within the O(N) model in the 1/N expansion. Using the auxiliary field technique, we compute the effective potential up to the next-t…
Dynamical electroweak symmetry breaking due to strong Yukawa interactions
Petr Benes, Tomas Brauner, Adam Smetana
We present a new mechanism for electroweak symmetry breaking (EWSB) based on a strong Yukawa dynamics. We consider an SU(2)_L x U(1)_Y gauge invariant model endowed with the usual…
BCS-BEC crossover in dense relativistic matter: Collective excitations
Tomas Brauner
We study the relativistic BCS-BEC crossover within a class of Nambu-Jona-Lasinio type models, including arbitrary Lorentz-scalar pairing channels. Using the mean-field approximatio…
Linear sigma model at finite density in the 1/N expansion to next-to-leading order
Jens O. Andersen, Tomas Brauner
We study relativistic Bose-Einstein condensation at finite density and temperature using the linear sigma model in the one-particle-irreducible 1/N-expansion. We derive the effecti…
