Obtaining the Spectral Function of Moiré Graphene Heavy-Fermions Using Iterative Perturbation Theory
Dumitru Călugăru, Haoyu Hu, Lorenzo Crippa +6
The spectral functions of twisted bilayer graphene (TBG) in the absence of strain have recently been investigated in both the symmetric and symmetry-broken phases using dynamical m…
Interplay between many-body correlations, strain and lattice relaxation in twisted bilayer graphene
Lorenzo Crippa, Gautam Rai, Dumitru Călugăru +6
In twisted bilayer graphene, a unified understanding of the mechanisms governing temperature-dependent electronic spectra and thermodynamic properties remains controversial despite…
Next-generation EDIpack: A Lanczos-based package for quantum impurity models featuring general broken-symmetry phases, flexible bath topologies and multi-platform interoperability
Lorenzo Crippa, Igor Krivenko, Samuele Giuli +10
We present a next-generation version of EDIpack, a flexible, high-performance numerical library using Lanczos-based exact diagonalization to solve generic quantum impurity problems…
Resolving Intervalley Gaps and Many-Body Resonances in Moiré Superconductor
Hyunjin Kim, Gautam Rai, Lorenzo Crippa +15
Magic-angle twisted multilayer graphene stands out as a highly tunable class of moiré materials that exhibit strong electronic correlations and robust superconductivity. However, u…
Fragility of local moments against hybridization with flat bands
Max Fischer, Arianna Poli, Lorenzo Crippa +5
The Kondo screening of a localized magnetic moment crucially depends on the spectral properties of the electronic bath to which it is coupled. Unlike textbook examples, realistic s…
Probing Green's Function Zeros by Co-tunneling through Mott Insulators
Carl Lehmann, Lorenzo Crippa, Giorgio Sangiovanni +1
Quantum tunneling experiments have provided deep insights into basic excitations occurring as Green's function poles in the realm of complex quantum matter. However, strongly corre…
