Renormalized energy of ground and first excited state of Fröhlich polaron in the range of weak coupling

open access: yesCondensed Matter Physics, 2015
The partial summing of infinite range of diagrams for the two-phonon mass operator of polaron described by Frohlich Hamiltonian is performed using the Feynman-Pines diagram technique.

Correlators in non-conformal N $$ \mathcal{N} $$ = 2 gauge theories from localization

open access: yesJournal of High Energy Physics
We study two-point correlation functions of chiral/anti-chiral operators in SU(N) N $$ \mathcal{N} $$ = 2 gauge theories with massless hyper-multiplets in a representation R $$ \mathcal{R} $$ associated with a non-vanishing β-function.
