Dynamical correlations and order in magic-angle twisted bilayer graphene
Gautam Rai, Lorenzo Crippa, Dumitru Călugăru +8
In magic angle twisted bilayer graphene, transport, thermodynamic and spectroscopic experiments pinpoint at a competition between distinct low-energy states with and without electr…
Protection of Correlation-Induced Phase Instabilities by Exceptional Susceptibilities
Matthias Reitner, Lorenzo Crippa, Dominik Robert Fus +3
At thermal equilibrium, we find that generalized susceptibilities encoding the static physical response properties of Hermitian many-electron systems possess inherent non-Hermitian…
Heterogeneous Ta-dichalcogenide bilayer: heavy fermions or doped Mott physics?
Lorenzo Crippa, Hyeonhu Bae, Paul Wunderlich +5
Controlling and understanding electron correlations in quantum matter is one of the most challenging tasks in materials engineering. In the past years a plethora of new puzzling co…
Symmetric Kondo Lattice States in Doped Strained Twisted Bilayer Graphene
H. Hu, G. Rai, L. Crippa +7
We use the topological heavy fermion (THF) model and its Kondo Lattice (KL) formulation to study the symmetric Kondo state in twisted bilayer graphene. Via a large-N approximation,…
Mott insulators with boundary zeros
Niklas Wagner, Lorenzo Crippa, Adriano Amaricci +9
The topological classification of electronic band structures is based on symmetry properties of Bloch eigenstates of single-particle Hamiltonians. In parallel, topological field th…
