RG domain wall for the N=1 minimal superconformal models
Gabriel Poghosyan, Hasmik Poghosyan
We specify Gaiotto's proposal for the RG domain wall between some coset CFT models to the case of two minimal N=1 SCFT models and related by the RG flow initiated…
On a Gopakumar-Vafa form of partition function of Chern-Simons theory on classical and exceptional lines
R. L. Mkrtchyan
We show that partition function of Chern-Simons theory on three-sphere with classical and exceptional groups (actually on the whole corresponding lines in Vogel's plane) can be rep…
A matrix model for strings beyond the c=1 barrier: the spin-s Heisenberg model on random surfaces
J. Ambjorn, Sh. Khachatryan, A. Sedrakyan
We consider a spin-s Heisenberg model coupled to two-dimensional quantum gravity. We quantize the model using the Feynman path integral, summing over all possible two-dimensional g…
Modular anomaly equations in N=2* theories and their large-N limit
M. Billo, M. Frau, F. Fucito +4
We propose a modular anomaly equation for the prepotential of the N=2* super Yang-Mills theory on R^4 with gauge group U(N) in the presence of an Omega-background. We then study th…
Effective QCD string beyond Nambu-Goto
J. Ambjorn, Y. Makeenko, A. Sedrakyan
We consider the QCD string as an effective string, whose action describes long-range stringy fluctuations. The leading infrared contribution to the ground state energy is given by…
The structure of invariants in conformal mechanics
Tigran Hakobyan, David Karakhanyan, Olaf Lechtenfeld
We investigate the integrals of motion of general conformal mechanical systems with and without confining harmonic potential as well as of the related angular subsystems, by employ…
