Charge Density Wave Ordering in NdNiO: Effects of Multiorbital Nonlocal Correlations
Evgeny A. Stepanov, Matteo Vandelli, Alexander I. Lichtenstein +1
In this work, we investigate collective electronic fluctuations and, in particular, the possibility of the charge density wave ordering in an infinite-layer NdNiO. We perform a…
Doping-dependent charge- and spin-density wave orderings in a monolayer of Pb adatoms on Si(111)
Matteo Vandelli, Anna Galler, Angel Rubio +3
In this work we computed the phase diagram as a function of temperature and doping for a system of lead adatoms allocated periodically on a silicon (111) surface. This Si(111):Pb m…
Multi-band D-TRILEX approach to materials with strong electronic correlations
Matteo Vandelli, Josef Kaufmann, Mohammed El-Nabulsi +3
We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation. This method is des…
Extended regime of coexisting metallic and insulating phases in a two-orbital electronic system
M. Vandelli, J. Kaufmann, V. Harkov +3
We investigate the metal-to-insulator phase transition driven by the density-density electronic interaction in the quarter-filled model on a cubic lattice with two orbitals split b…
Impact of partially bosonized collective fluctuations on electronic degrees of freedom
V. Harkov, M. Vandelli, S. Brener +2
In this work we present a comprehensive analysis of collective electronic fluctuations and their effect on single-particle properties of the Hubbard model. Our approach is based on…
Dual Boson Diagrammatic Monte Carlo Approach Applied to the Extended Hubbard Model
M. Vandelli, V. Harkov, E. A. Stepanov +4
In this work we introduce the Dual Boson Diagrammatic Monte Carlo technique for strongly interacting electronic systems. This method combines the strength of dynamical mean-filed t…
Nonlinear optical study of commensurability effects in graphene-hBN heterostructures
E. A. Stepanov, S. V. Semin, C. R. Woods +4
Second-order nonlinear optical response allows to detect different properties of the system associated with the inversion symmetry breaking. Here, we use a second harmonic generati…
Resonant optical second harmonic generation in graphene-based heterostructures
M. Vandelli, M. I. Katsnelson, E. A. Stepanov
An optical Second-Harmonic Generation (SHG) allows to probe various structural and symmetry-related properties of materials, since it is sensitive to the inversion symmetry breakin…
