Sign problem in finite density lattice QCD
V. A. Goy, V. Bornyakov, D. Boyda +4
The canonical approach, which was developed for solving the sign problem, may suffer from a new type of sign problem. In the canonical approach, the grand partition function is wri…
Study of lattice QCD at finite chemical potential using canonical ensemble approach
V. G. Bornyakov, D. L. Boyda, V. A. Goy +4
New approach to computation of canonical partition functions in lattice QCD is presented. We compare results obtained by new method with results obtained by known method of…
Study of lattice QCD at finite baryon density using the canonical approach
V. G. Bornyakov, D. L. Boyda, V. A. Goy +4
At finite baryon density lattice QCD first-principle calculations can not be performed due to the sign problem. In order to circumvent this problem, we use the canonical approach,…
Dyons and Roberge - Weiss transition in lattice QCD
V. G. Bornyakov, D. L. Boyda, V. A. Goy +6
We study lattice QCD with Wilson fermions at nonzero imaginary chemical potential and nonzero temperature. We relate the Roberge - Weiss phase transition to the properties…
New approach to canonical partition functions computation in lattice QCD at finite baryon density
V. G. Bornyakov, D. L. Boyda, V. A. Goy +4
We propose and test a new approach to computation of canonical partition functions in lattice QCD at finite density. We suggest a few steps procedure. We first compute numerically…
Many-body effects on graphene conductivity: Quantum Monte Carlo calculations
D. L. Boyda, V. V. Braguta, M. I. Katsnelson +1
Optical conductivity of graphene is studied using Quantum Monte Carlo calculations. We start from Euclidean current-current correlator and extract from Green-Kubo relations…
