Towards high-temperature coherence-enhanced transport in few-atomic layers heterostructures
Chahan M. Kropf, Angelo Valli, Paolo Franceschini +4
The possibility to exploit quantum coherence to strongly enhance the efficiency of charge transport in solid state devices working at ambient conditions would pave the way to disru…
Momentum-dependent relaxation dynamics of the doped repulsive Hubbard model
Sharareh Sayyad, Naoto Tsuji, Abolhassan Vaezi +3
We study the dynamical behavior of doped electronic systems subject to a global ramp of the repulsive Hubbard interaction. We start with formulating a real-time generalization of t…
Rashba-metal to Mott-insulator transition
Valentina Brosco, Massimo Capone
The recent discovery of materials featuring strong Rashba spin-orbit coupling (RSOC) and strong electronic correlation raises questions about the interplay of Mott and Rashba physi…
Two-particle Fermi liquid parameters at the Mott transition: Vertex divergences, Landau parameters, and incoherent response in dynamical mean-field theory
Friedrich Krien, Erik G. C. P. van Loon, Mikhail I. Katsnelson +2
We consider the interaction-driven Mott transition at zero temperature from the viewpoint of microscopic Fermi liquid theory. To this end, we derive an exact expression for the Lan…
Emergent symmetry in fully-relaxed magic-angle twisted bilayer graphene
M. Angeli, D. Mandelli, A. Valli +4
We present a tight-binding calculation of a twisted bilayer graphene at magic angle , allowing for full, in- and out-of-plane, relaxation of the atomic positions.…
Interplay between destructive quantum interference and symmetry-breaking phenomena in graphene quantum junctions
Angelo Valli, Adriano Amaricci, Valentina Brosco +1
We study the role of electronic spin and valley symmetry in the quantum interference (QI) patterns of the transmission function in graphene quantum junctions. In particular, we lin…
Exciton Mott transition revisited
Daniele Guerci, Massimo Capone, Michele Fabrizio
The dissociation of excitons into holes and electrons in photoexcited semiconductors, despite being one of the first recognized examples of a Mott transition, still defies a comple…
Enhanced performance of a quantum-dot-based nanomotor due to Coulomb interactions
Maria Florencia Ludovico, Massimo Capone
We study the relation between quantum pumping of charge and the work exchanged with the driving potentials in a strongly interacting ac-driven quantum dot. We work in the large-int…
Dynamical vertex approximation for the attractive Hubbard model
Lorenzo Del Re, Massimo Capone, Alessandro Toschi
In this work, we adapt the formalism of the dynamical vertex approximation (DA), a diagrammatic approach including many-body correlations beyond the dynamical mean-field theory,…
Correlation-driven Lifshitz transition and orbital order in a two-band Hubbard model
Francesco Grandi, Adriano Amaricci, Massimo Capone +1
We study by dynamical mean field theory the ground state of a quarter-filled Hubbard model of two bands with different bandwidths. At half-filling, this model is known to display a…
Ultrafast orbital manipulation and Mott physics in multi-band correlated materials
Andrea Ronchi, Paolo Franceschini, Laura Fanfarillo +12
Multiorbital correlated materials are often on the verge of multiple electronic phases (metallic, insulating, super- conducting, charge and orbitally ordered), which can be explore…
Pauli metallic ground-state in Hubbard clusters with Rashba spin-orbit coupling
Valentina Brosco, Daniele Guerci, Massimo Capone
We study the "phase diagram" of a Hubbard plaquette with Rashba spin-orbit coupling. We show that the peculiar way in which Rashba coupling breaks the spin-rotational symmetry of t…
