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 Breather-like structures in modified sine-Gordon models To cite this article: L A Ferreira and Wojtek J Zakrzewski 2016 Nonlinearity 29 1622 View the article online for updates and enhancements. Related content Q-balls, integrability and duality Peter Bowcock, David Foster and Paul Sutcliffe-Breaking integrability at the boundary: the Multiple fluxon solutions, i.e., solitary wave solutions that connect fixed points separated by integer multiples of $2\pi $, are also studied. The solution curves for the multiple fluxons exhibit the same qualitative behavior as those for the single fluxon case. We study bosonization of the sine-Gordon theory in the presence of boundary interactions at the free fermion point.

We investigate the free-Fermion point of a boundary sine-Gordon model with nondiagonal boundary interactions for the ground state using auxiliary functions, obtained from T-Q equations of a corresponding inhomogeneous open spin-1/2 XXZ chain with nondiagonal boundary terms. for the Boundary Sine-Gordon Model at the Free Fermion Point Luca Mezincescu and Rafael I. Nepomechie Physics Department, P.O. Box 248046, University of Miami Coral Gables, FL 33124 USA Abstract We construct integrals of motion (IM) for the sine-Gordon model with boundary at the free Fermion point ( 2 =4ˇ) which correctly determine the boundary Smatrix. Out-of-equilibrium transport in the interacting resonant level model: Surprising relevance of the boundary sine-Gordon model Kemal Bidzhiev, Grégoire Misguich, and Hubert Saleur Phys. Rev. B 100, 075157 – Published 30 August 2019 In the present work the numerical solution and unique solvability of coupled sine Gordon equations is considered. A composite numerical method based on ﬁnite diﬀerence method and ﬁxed point iteration is implemented to solve coupled sine-Gordon equations with appropriate initial and boundary conditions.

We investigate the free-Fermion point of a boundary sine-Gordon model with nondiagonal boundary interactions for the ground state using auxiliary functions obtained from T - Q equations of a corresponding inhomogeneous open spin-\\frac{1}{2} XXZ chain with nondiagonal boundary terms. In particular, we obtain the Casimir energy. Our result for the Casimir energy is shown to agree with the

Through the partition function, we show that boundary sine-Gordon maps onto a doubled boundary Ising model. With the current-current correlators, we calculate for finite system size the ac-conductance of tunneling quantum wires with dimensionless free conductance 1/2 (or, alternatively interacting quantum Hall edges Using the path-integral approach, the quantum massive Thirring and sine-Gordon models are proven to be equivalent at finite temperature.
