Quantum phase transitions on the hexagonal lattice
Dominik Smith, Pavel Buividovich, Michael Körner +2
Hubbard-type models on the hexagonal lattice are of great interest, as they provide realistic descriptions of graphene and other related materials. Hybrid Monte Carlo simulations o…
Numerical evidence of conformal phase transition in graphene with long-range interactions
Pavel Buividovich, Dominik Smith, Maksim Ulybyshev +1
Using state of the art Hybrid-Monte-Carlo (HMC) simulations we carry out an unbiased study of the competition between spin-density wave (SDW) and charge-density wave (CDW) order in…
Hybrid-Monte-Carlo study of competing order in the extended fermionic Hubbard model on the hexagonal lattice
Pavel Buividovich, Dominik Smith, Maksim Ulybyshev +1
Using first-principle Hybrid-Monte-Carlo (HMC) simulations, we carry out an unbiased study of the competition between spin-density wave (SDW) and charge-density wave (CDW) order in…
A Hybrid-Monte-Carlo study of monolayer graphene with partially screened Coulomb interactions at finite spin density
Michael Körner, Dominik Smith, Pavel Buividovich +2
We report on Hybrid-Monte-Carlo simulations at finite spin density of the -band electrons in monolayer graphene with realistic inter-electron interactions. Unlike simulations at…
Inter-electron interactions and the RKKY potential between H adatoms in graphene
Pavel Buividovich, Dominik Smith, Maksim Ulybyshev +1
We use first-principles Quantum Monte-Carlo simulations to study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between hydrogen adatoms attached to a graphene sheet. We find…
