Electronic structure of graphene: (nearly) free electrons bands vs. tight-binding bands
E. Kogan, V. M. Silkin
In our previous paper (Phys. Rev. B {\bf 89}, 165430 (2014)) we have found that in graphene, in distinction to the four occupied bands, which can be described by the simple tight-b…

Critical behaviour of anisotropic magnets with quenched disorder: replica symmetry breaking studied by operator product expansion
E. Kogan, M. Kaveh
We study critical behaviour of disordered magnets near four dimensions. We consider the system with explicit cubic anisotropy and scalar disorder and that with random direction of…

Replica symmetry breaking for anisotropic magnets with quenched disorder
E. Kogan, M. Kaveh
We study critical behaviour of a magnet with cubic anisotropy and quenched scalar disorder which is taken into account by replica method. We derive to first order in approximat…
