Sine-Gordon model in functional renormalization

چکیده
SU(N) Yang-Mills theories, which are expected to describe the strong interaction in the case N = 3, are one of the most studied models in theoretical physics. While their asymptotic UV behavior is well under control thanks to asymptotic freedom, the need of non-perturbative techniques to describe the IR behavior has rapidly appeared to be mandatory. The reasons of this non-perturbativity of the IR are actually two-fold:

Sine-Gordon field theory for the Kosterlitz-Thouless transitions on fluctuating membranes.
In the preceding paper, we derived Coulomb-gas and sine-Gordon Hamiltonians to describe the Kosterlitz-Thouless transition on a fluctuating surface. These Hamiltonians contain couplings to Gaussian curvature not found in a rigid flat surface. In this paper, we derive renormalization-group recursion relations for the sine-Gordon model using field-theoretic techniques developed to study flat spac...
متن کاملThe Large N Random Phase sine - Gordon Model
At large distances and in the low temperature phase, the quenched correlation functions in the 2d random phase sine-Gordon model have been argued to be of the form : [ϕ(x) − ϕ(0)] 2 * = A(log |x|) + Bǫ 2 (log |x|) 2 , with ǫ = (T − T c). However, renormalization group computations predict B = 0 while variational approaches (which are supposed to be exact for models with a large number of compon...
متن کاملSine-gordon Revisited
We study the sine-Gordon model in two dimensional space time in two different domains. For β > 8π and weak coupling, we introduce an ultraviolet cutoff and study the infrared behavior. A renormalization group analysis shows that the the model is asymptotically free in the infrared. For β < 8π and weak coupling, we introduce an infrared cutoff and study the ultraviolet behavior. A renormalizatio...
متن کاملGeneralized solution of Sine-Gordon equation
In this paper, we are interested to study the Sine-Gordon equation in generalized functions theory introduced by Colombeau, in the first we give result of existence and uniqueness of generalized solution with initial data are distributions (elements of the Colombeau algebra). Then we study the association concept with the classical solution.
متن کاملQuantum Aspects of the Noncommutative Sine - Gordon Model
In this paper, we first use semi-classical methods to study quantum field theoretical aspects of the integrable noncommutative sine-Gordon model proposed in [hep-th/0406065]. In particular, we examine the fluctuations at quadratic order around the static kink solution using the background field method. We derive equations of motion for the fluctuations and argue that at O(θ2) the spectrum of fl...
