Competing order in the fermionic Hubbard model on the hexagonal graphene lattice
Pavel Buividovich, Dominik Smith, Maksim Ulybyshev +1
We study the phase diagram of the fermionic Hubbard model on the hexagonal lattice in the space of on-site and nearest neighbor couplings with Hybrid-Monte-Carlo simulations. With…

Green functions in graphene monolayer with Coulomb interactions taken into account
M. V. Ulybyshev, M. A. Zubkov
We consider the low energy effective field model of graphene monolayer. Coulomb interactions are taken into account. The model is simulated numerically using the lattice discretiza…
