Using the path-integral approach, the quantum massive Thirring and sine-Gordon models are proven to be equivalent at finite temperature. This result is an extension of Coleman’s proof of the equivalence between both theories at zero temperature. The usual identifications among the parameters of these models also remain valid at T≠0.

We consider the sine-Gordon model on a half-line, with an additional potential term of the form −M scattering with fixed boundary conditions. 6 The point is.

The sinh-Gordon theory in the bulk is defined by the Lagrangian density L = 1 2 (∂ μ Φ) 2 − m 2 b 2 (c o s h b Φ − 1) It can be considered as the analytic continuation of the sine-Gordon model for imaginary coupling. 2006-02-22 · The boundary Lagrangian we will use for the sine-Gordon model is of the same type as those used in [21, 22]. It would be very interesting to see how to employ the methods of the previous references in the case of non-homogeneous worldsheet superpotentials to obtain further insight, for example, into the spectrum of the boundary theory. BOUND STATE BOUNDARY S MATRIX OF THE SINE-GORDON MODEL.

The boundary Coleman-Thun mechanism plays an important role in the analysis. Two basic lemmas are introduced which should hold for any 1+1-dimensional boundary eld theory, allowing 1995-07-20 · We study bosonization of the sine-Gordon theory in the presence of boundary interactions at the free fermion point. In this way we obtain the boundary S-matrix as a function of physical parameters in the boundary sine-Gordon Lagrangian. The boundary S-matrix can be matched onto the solution of Ghoshal and Zamolodchikov, thereby relating the formal parameters in the latter solution to the physical parameters in the lagrangian. 2011-11-21 · Boundary sinh-Gordon model. The sinh-Gordon theory in the bulk is defined by the Lagrangian density L = 1 2 (∂ μ Φ) 2 − m 2 b 2 (c o s h b Φ − 1) It can be considered as the analytic continuation of the sine-Gordon model for imaginary coupling.

In earlier work, in the setting of bluff body flow, the use of no slip boundary I think the point was that the murderer's identity wasn't who he was, but what he was.

The boundary Coleman-Thun mechanism plays an important role in the analysis.

These include the so-called homogeneous and symmetric space sine-Gordon models, discrete and supersymmetric versions, and generalizations to higher-dimensional spacetimes (i.e., in [1] the spatial derivative is replaced by the Laplace operator in several variables). arXiv:0705.3928v1 [hep-th] 27 May 2007 Dissipative Hofstadter Model at the Magic Points and Critical Boundary Sine-Gordon Model Seungmuk Ji Department of Physics, Kangwon National University We study in this paper the sine-Gordon model using functional Renormalization Group (fRG) at Local Potential Approximation (LPA) using different RG schemes.

We examine the properties of solutions to the sine-Gordon equation in the presence of various boundary conditions. Reflection from the boundary of a semi-infinite system with a fixed or free endpoint is found to be explainable in terms of the standard soliton-soliton and soliton-antisoliton solutions, respectively, for the infinite system.
