Critical behavior of isotropic systems with strong dipole-dipole interaction from the functional renormalization group
Georgii Kalagov, Nikita Lebedev
We compute the critical exponents of three-dimensional magnets with strong dipole-dipole interactions using the functional renormalization group (FRG) within the local potential ap…

Functional renormalization group equations for antisymmetric tensor field models at finite temperature
Georgii Kalagov
Within the framework of the functional renormalization group, we derived the flow equations for the scale-dependent effective action at finite temperature for models involving an a…

Fluctuation-induced first-order superfluid transition in unitary Fermi gases
Georgii Kalagov
We investigate the superfluid phase transition in an -symmetric Fermi gas with distinct spin states using the functional renormalization group. To capture pairi…
