The boundary sine-Gordon theory: classical and semi-classical analysis
We consider the sine-Gordon model on a half-line, with an additional potential term of the form −M cos β2 (φ − φ0) at the boundary. We compute the classical time delay for general values of M , β and φ0 using τ -function methods and show that in the classical limit, the method of images still works, despite the non-linearity of the problem. We also perform a semi-classical analysis, and find ag...
متن کاملThe boundary supersymmetric sine-Gordon model revisited
We argue that, contrary to previous claims, the supersymmetric sine-Gordon model with boundary has a two-parameter family of boundary interactions which preserves both integrability and supersymmetry. We also propose the corresponding boundary S matrix for the first supermultiplet of breathers.
متن کاملIntegrable boundary conditions for classical sine-Gordon theory
The possible boundary conditions consistent with the integrability of the classical sine-Gordon equation are studied. A boundary value problem on the half-line x ≤ 0 with local boundary condition at the origin is considered. The most general form of this boundary condition is found such that the problem be integrable. For the resulting system an infinite number of involutive integrals of motion...
متن کاملClassical Matrix sine - Gordon Theory
The matrix sine-Gordon theory, a matrix generalization of the well-known sine-Gordon theory, is studied. In particular, the A3-generalization where fields take value in SU(2) describes integrable deformations of conformal field theory corresponding to the coset SU(2)× SU(2)/SU(2). Various classical aspects of the matrix sine-Gordon theory are addressed. We find exact solutions, solitons and bre...
متن کاملCritical Boundary Sine-Gordon Revisited
We revisit the exact solution of the two space-time dimensional quantum field theory of a free massless boson with a periodic boundary interaction and self-dual period. We analyze the model by using a mapping to free fermions with a boundary mass term originally suggested in ref. [22]. We find that the entire SL(2,C) family of boundary states of a single boson are boundary sine-Gordon states an...
