dc.description.abstract | We consider the massive vector N-component (λϕ4)D theory in Euclidean space and, using an extended Matsubara formalism we perform a compactification on a d-dimensional subspace, d⩽D. This allows us to treat jointly the effect of temperature and spatial confinement in the effective potential of the model, setting forth grounds for an analysis of phase transitions driven by temperature and spatial boundary. For d=2, which corresponds to the heated system confined between two parallel planes (separation L), we obtain, in the large N limit at one-loop order, formulas for temperature- and boundary-dependent mass and coupling constant. The equation for the critical curve in the β×L plane is also derived. | pt_BR |
