Tricritical Ising Model with a Boundary ∗
We study the integrable and supersymmetric massivê φ (1,3) deformation of the tricritical Ising model in the presence of a boundary. We use constraints from su-persymmetry in order to compute the exact boundary S-matrices, which turn out to depend explicitly on the topological charge of the supersymmetry algebra. We also solve the general boundary Yang-Baxter equation and show that in appropria...
متن کاملExact ( d ) 7 → ( + ) & ( − ) boundary flow in the tricritical Ising model
The integrable perturbation of the degenerate boundary condition (d) by the φ1,3 boundary field generates a renormalization group flow down to the superposition of Cardy boundary states (+)&(−). Exact Thermodynamic Bethe Ansatz (TBA) equations for all the excited states are derived here extending the results of [1] to this case. As an intermediate step, the non-Cardy boundary conformal sector (...
متن کاملTricritical Ising Model near criticality
The most relevant thermal perturbation of the continuous d = 2 minimal conformal theory with c = 7/10 (Tricritical Ising Model) is treated here. This model describes the scaling region of the φ universality class near the tricritical point. The problematic IR divergences of the naive perturbative expansion around conformal theories are dealt within the OPE approach developed at all orders by th...
متن کاملTBA boundary flows in the tricritical Ising field theory
Boundary S matrices for the boundary tricritical Ising field theory (TIM), both with and without supersymmetry, have previously been proposed. Here we provide support for these S matrices by showing that the corresponding boundary entropies are consistent with the expected boundary flows. We develop the fusion procedure for boundary RSOS models, with which we derive exact inversion identities f...
متن کاملSupersymmetry in the boundary tricritical Ising field theory
We argue that it is possible to maintain both supersymmetry and integrability in the boundary tricritical Ising field theory. Indeed, we find two sets of boundary conditions and corresponding boundary perturbations which are both supersymmetric and integrable. The first set corresponds to a “direct sum” of two non-supersymmetric theories studied earlier by Chim. The second set corresponds to a ...
