From local to non-local correlations: the Dual Boson perspective
E. A. Stepanov, A. Huber, E. G. C. P. van Loon +2
Extended dynamical mean-field theory (EDMFT) is insufficient to describe non-local effects in strongly correlated systems, since corrections to the mean-field solution are generall…
Graphene under the influence of Aharonov-Bohm flux and constant magnetic field
E. A. Stepanov, V. Ch. Zhukovsky
Investigation of real two-dimensional systems with Dirac-like electronic behavior under the influence of magnetic field is challenging and leads to many interesting physical result…
Double occupancy in DMFT and the Dual Boson approach
Erik G. C. P. van Loon, Friedrich Krien, Hartmut Hafermann +3
We discuss the calculation of the double occupancy using Dynamical Mean-Field Theory (DMFT) in finite dimensions. The double occupancy can be determined from the susceptibility of…
Laser-induced topological transitions in phosphorene with inversion symmetry
C. Dutreix, E. A. Stepanov, M. I. Katsnelson
Recent ab initio calculations and experiments reported insulating-semimetallic phase transitions in multilayer phosphorene under a perpendicular dc field, pressure or doping, as a…
