Harmonic Analysis and Free Field Realization of the Takiff Supergroup of GL(1|1)
Andrei Babichenko, Thomas Creutzig
Takiff superalgebras are a family of non semi-simple Lie superalgebras that are believed to give rise to a rich structure of indecomposable representations of associated conformal…
Finite-gap equations for strings on AdS_3 x S^3 x T^4 with mixed 3-form flux
Andrei Babichenko, Amit Dekel, Olof Ohlsson Sax
We study superstrings on AdS_3 x S^3 x T^4 supported by a combination of Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz three form fluxes, and construct a set of finite-gap equation…
Nonstandard Parafermions and String Compactification
Andrei Babichenko, Doron Gepner
Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions wi…
Thermodynamic Bethe ansatz for the AII sigma-models
Andrei Babichenko, Roberto Tateo
We derive thermodynamic Bethe ansatz equations describing the vacuum energy of the SU(2N)/Sp(N) nonlinear sigma model on a cylinder geometry. The starting points are the recently-p…
Principal chiral model scattering and the alternating quantum spin chain
Anastasia Doikou, Andrei Babichenko
We consider the critical alternating quantum spin chain with , spins. Using the Bethe ansatz technique we find explicit expressions for the -mat…
Integrable vector perturbations of W-invariant theories and their quantum group symmetry
A. Babichenko
Perturbations of and conformal theories which generalize the perturbations of conformal minimal models are shown to be integrable by counting argument. $A_{2n-…
