The O(2) model in polar coordinates at nonzero temperature
Mara Grahl, Elina Seel, Francesco Giacosa +1
We study the restoration of spontaneously broken symmetry at nonzero temperature in the framework of the O(2) model using polar coordinates. We apply the CJT formalism to calculate…

Thermodynamics of the O(4) linear and nonlinear models within the auxiliary field method
Elina Seel
The study of the O(N) model at nonzero temperature is presented applying the auxiliary field method, which allows to obtain a continuous transformation between the linear and the n…

Study of chiral symmetry restoration in linear and nonlinear O(N) models using the auxiliary field method
Elina Seel, Stefan Struber, Francesco Giacosa +1
We consider the O(N) linear σ model and introduce an auxiliary field to eliminate the scalar self-interaction. Using a suitable limiting process this model can be continuously tran…
