Entanglement, noise, and the cumulant expansion
Joaquín E. Drut, William J. Porter
We put forward a simpler and improved variation of a recently proposed method to overcome the signal-to-noise problem found in Monte Carlo calculations of the entanglement entropy…
A hybrid Monte Carlo approach to the entanglement entropy of interacting fermions
Joaquín E. Drut, William J. Porter
The Monte Carlo calculation of Rényi entanglement entropies of interacting fermions suffers from a well-known signal-to-noise problem, even for a large number of situation…
Velocity renormalization in graphene from lattice Monte Carlo
Joaquín E. Drut, Timo A. Lähde
We compute the Fermi velocity of the Dirac quasiparticles in clean graphene at the charge neutrality point for strong Coulomb coupling alpha_g. We perform a Lattice Monte Carlo cal…
Signatures of a gap in the conductivity of graphene
Joaquín E. Drut, Timo A. Lähde, Eero Tölö
The electrical conductivity of suspended graphene has recently been measured for the first time, and found to behave as σ~ \sqrt{|n|} as expected for Dirac quasiparticles at large…
First-order chiral transition in the compact lattice theory of graphene and the case for improved actions
Joaquín E. Drut, Timo A. Lähde, Lauri Suoranta
A comparison of the compact and non-compact lattice versions of the low-energy theory of graphene is presented. The compact theory is found to exhibit a chiral phase transition whi…
Critical exponents of the semimetal-insulator transition in graphene: A Monte Carlo study
Joaquín E. Drut, Timo A. Lähde
The low-energy theory of graphene exhibits spontaneous chiral symmetry breaking due to pairing of quasiparticles and holes, corresponding to a semimetal-insulator transition at str…
