Interplay between many-body correlations, strain and lattice relaxation in twisted bilayer graphene
Lorenzo Crippa, Gautam Rai, Dumitru CÄlugÄru +6
In twisted bilayer graphene, a unified understanding of the mechanisms governing temperature-dependent electronic spectra and thermodynamic properties remains controversial despite…
Obtaining the Spectral Function of Moiré Graphene Heavy-Fermions Using Iterative Perturbation Theory
Dumitru CÄlugÄru, 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…
Site-polarized Mott phases competing with a correlated metal in twisted WSe
Siheon Ryee, Lennart Klebl, Gautam Rai +9
Twisted WSe hosts superconductivity, metal-insulator phase transitions, and field-controllable Fermi-liquid to non-Fermi-liquid transport properties. In this work, we use dynam…
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,…
