Fluctuating field series: towards calculations of correlated systems with high accuracy
Ya. S. Lyakhova, S. D. Semenov, A. I. Lichtenstein +1
We introduce regular series expansion for weakly- and moderately-correlated fermionic systems, based on Fluctuating Local Field approach. The method relies on the explicit account…
Perturbative solution of fermionic sign problem in lattice Quantum Monte Carlo
Sergei Iskakov, Mikhail I. Katsnelson, Alexander I. Lichtenstein
We develop a strong-coupling perturbation scheme for a generic Hubbard model around a half-filled particle-hole-symmetric reference system, which is free from the fermionic sign pr…
Local Plaquette Physics as Key Ingredient of High-Temperature Superconductivity in Cuprates
M. Danilov, E. G. C. P. van Loon, S. Brener +3
A major pathway towards understanding complex systems is given by exactly solvable reference systems that contain the essential physics of the system. For the Hubbard mode…
Relativistic exchange interactions in CrX (X=Cl, Br, I) monolayers
Y. O. Kvashnin, A. Bergman, A. I. Lichtenstein +1
It has been predicted theoretically and indirectly confirmed experimentally that single-layer CrX (X=Cl, Br, I) might be the prototypes of topological magnetic insulators (TMI)…
Dynamically induced doublon repulsion in the Fermi-Hubbard model probed by a single-particle density of states
V. N. Valmispild, C. Dutreix, M. Eckstein +3
We investigate the possibility to control dynamically the interactions between repulsively bound pairs of fermions (doublons) in correlated systems with off-resonant ac fields. We…
Introducing strong correlation effects into graphene by gadolinium intercalation
S. Link, S. Forti, A. Stöhr +11
Exotic ordered ground states driven by electronic correlations are expected to be induced in monolayer graphene when doped to the Van Hove singularity. Such doping levels are reach…
