Reflection Factors for the Principal Chiral Model
نویسنده
چکیده
We consider the SU (2) Principal Chiral Model (at level k = 1) on the half-line with scale invariant boundary conditions. By looking at the IR limiting confor-mal field theory and comparing with the Kondo problem, we propose the set of permissible boundary conditions and the corresponding reflection factors.

Plane Wave Reflection and Transmission from Uni- and Bi-Axial Chiral Slabs
In this paper, the propagation of electromagnetic waves through an infinite slab of uni- or bi- axial chiral medium is analytically formulated for an arbitrary incidence using 4×4 matrix method. In this powerful method, a state vector differential equation is extracted whose solution is given in terms of a transition matrix relating the tangential components of electric and magnetic fields at t...
متن کاملBoundary remnant of Yangian symmetry and the structure of rational reflection matrices
For the classical principal chiral model with boundary, we give the subset of the Yangian charges which remains conserved under certain integrable boundary conditions, and extract them from the monodromy matrix. Quantized versions of these charges are used to deduce the structure of rational solutions of the reflection equation, analogous to the ‘tensor product graph’ for solutions of the Yang-...
متن کاملThe SO(N) principal chiral field on a half-line
We investigate the integrability of the SO(N) principal chiral model on a halfline, and find that mixed Dirichlet/Neumann boundary conditions (as well as pure Dirichlet or Neumann) lead to infinitely many conserved charges classically in involution. We use an anomaly-counting method to show that at least one non-trivial example survives quantization, compare our results with the proposed reflec...

We compute the boundary entropies for the allowed boundary conditions of the SU (2)-invariant principal chiral model at level k = 1. We used the reflection factors determined in previous work. As a by-product we obtain some miscellaneous results such as the ground-state energy for mixed boundary conditions as well as the degeneracies of the Kondo model in the underscreened and exactly screened ...
