Integrable Model of Boundary Interaction: The Paperclip
S. L. Lukyanov, E. S. Vitchev, A. B. Zamolodchikov
We consider a model of 2D quantum field theory on a disk, whose bulk dynamics is that of a two-component free massless Bose field (X,Y), and interaction occurs at the boundary, whe…
Higher-level eigenvalues of Q-operators and Schroedinger equation
V. V. Bazhanov, S. L. Lukyanov, A. B. Zamolodchikov
Relation between one-dimensional Schroedinger equation and the vacuum eigenvalues of the Q-operators is extended to their higher-level eigenvalues.
Integrable Circular Brane Model and Coulomb Charging at Large Conduction
S. L. Lukyanov, A. B. Zamolodchikov
We study a model of 2D QFT with boundary interaction, in which two-component massless Bose field is constrained to a circle at the boundary. We argue that this model is integrable…
Analytical results for the Coqblin-Schrieffer model with generalized magnetic fields
V. V. Bazhanov, S. L. Lukyanov, A. M. Tsvelik
Using the approach alternative to the traditional Thermodynamic Bethe Ansatz, we derive analytical expressions for the free energy of Coqblin-Schrieffer model with arbitrary magnet…
