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. We point out that a Josephson junction network with a pertinent impurity located at its center provides a physical realization of this boundary double Sine-Gordon model. For this Josephson junction network, we prove that the competition between the two boundary interactions stabilizes a robust finite coupling fixed point and, at a pertinent In the sequel, we shall show that a JJ-chain with a weak link at its center and ending with two bulk superconductors at fixed phase difference φ, is the prototype of a condensed matter realization of a two-boundary sine-Gordon model , whose Hamiltonian is given by (1) H = 1 4 π ∫ 0 L d x [1 v (∂ Φ ∂ t) 2 + v (∂ Φ ∂ x) 2] − Δ L In this report we compute the boundary states (including the boundary entropy) for the boundary sine-Gordon theory. From the boundary states, we derive both correlation and partit Superconducting Josephson chains with a weak link [18,22] and SQUIDs [19,23] may be indeed described by boundary sine Gordon models yielding a phase diagram with only two fixed points: an unstable the IR fixed point at 1=z ¼ 0 and u~ ¼ 1, which is IR attractive. Unfortunately, one cannot find this fixed point from the original evolution equations in Eq. (6) since it is situated at the singular point of the flow equation which makes the β functions divergent.

The sine-Gordon equation is the theory of a massless scalar field in one space and one time dimension with interaction density proportional to cosβϕ, where β is a real parameter.

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. This result is an extension of Coleman’s proof of the equivalence between both theories at zero temperature.

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. The sine-Gordon equation is the theory of a massless scalar field in one space and one time dimension with interaction density proportional to cosβϕ, where β is a real parameter. In this report we compute the boundary states (including the boundary entropy) for the boundary sine-Gordon theory.
