Magnetic field driven instability of charged center in graphene
O. V. Gamayun, E. V. Gorbar, V. P. Gusynin
It is shown that a magnetic field dramatically affects the problem of supercritical charge in graphene making any charge in gapless theory supercritical. The cases of radially symm…

Supercritical Coulomb center and excitonic instability in graphene
O. V. Gamayun, E. V. Gorbar, V. P. Gusynin
It is well known that there are resonant states with complex energy for the supercritical Coulomb impurity in graphene. We show that opening of a quasiparticle gap decreases the im…

First Order String Theory and the Kodaira-Spencer Equations. I
O. Gamayun, A. S. Losev, A. Marshakov
We consider first-order bosonic string theory, perturbed by the primary operator, corresponding to deformation of the target-space complex structure. We compute the effective actio…
