Toward the Pole
Sergey Alekseev, Alexander Gorsky, Mikhail Litvinov
We study the analytic structure of semiclassical conformal blocks, namely of the 1-point conformal block on the torus and of the 4-point conformal block on the sphere, as functions…

On resummation of the irregular conformal block
S. Alekseev, M. Litvinov
We discuss the resummation procedure of the superpotential in 4d SYM theory without matter from the point of view of 2d Liouville conformal field theory, utilizing…

Metal or Insulator? Dirac operator spectrum in holographic QCD
A. Gorsky, M. Litvinov
The lattice studies in QCD demonstrate the nontrivial localization behavior of the eigenmodes of the 4D Euclidean Dirac operator considered as Hamiltonian of dimensional diso…
