The Large N Limit and the High Temperature Phase Transition for the φ 4 Theory
نویسندگان
چکیده
We study, with various methods, the high temperature phase transition for the N-component φ 4 theory in the large N limit. Our results fully confirm a previous investigation of the problem, for arbitrary N , with the method of the average potential. The phase transition is of the second order with an effectively three-dimensional critical behaviour.

متن کاملOn the High T Phase Transition in the Gauged SU (2) Higgs Model
We study the effective field theory of a weakly coupled 3+1d gauged φ type model at high temperature. Our model has 4N real scalars (N complex Higgs doublets) and a gauge group SU(2) which is spontaneously broken by a nonzero scalar field vev at zero temperature. We find, for sufficiently large N , that the transition from the high temperature symmetry restoring phase to the low temperature pha...
متن کاملInvestigation into the temperature dependence of isotropic- nematic phase transition of Gay- Berne liquid crystals
Density functional approach was used to study the isotropic- nematic (I-N) transition and calculate the values of freezing parameters of the Gay- Berne liquid crystal model. New direct and pair correlation functions of a molecular fluid with Gay- Berne pair potential were used. These new functions were used in density functional theory as input to calculate the isotropic- nematic transition den...

We consider a theory of a scalar one-component field φ coupled to a scalar N-component field χ. Using large N techiques we calculate the effective potential in the leading order in 1/N. We show that this is equivalent to a resummation of an infinite subclass of graphs in perturbation theory, which involve fluctuations of the χ field only. We study the temperature dependence of the expectation v...
متن کاملThe phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
