Exactly solvable model for isospin S=3/2 fermionic atoms on an optical lattice
D. Controzzi, A. M. Tsvelik
We propose an exact solution of a model describing a low energy behavior of cold isospin S=3/2 fermionic atoms on a one-dimensional optical lattice. Depending on the band filling t…

Excitation spectrum of doped two-leg ladders: A field theory analysis
D. Controzzi, A. M. Tsvelik
We apply quantum field theory to study the excitation spectrum of doped two-leg ladders. It follows from our analysis that throughout most of the phase diagram the spectrum consist…

Paperclip at
S. L. Lukyanov, A. M. Tsvelik, A. B. Zamolodchikov
We study the ``paperclip'' model of boundary interaction with the topological angle equal to . We propose exact expression for the disk partition function in terms of soluti…
