Poles-zeros duality in semi-holographic Mott insulators
Thomas Kögel, Alessio Caddeo, Amelie Pitters +5
Inspired by the poles-zeros duality of Green's functions that appears in transitions into Mott-insulating phases in strongly correlated condensed matter systems, we propose a semi-…
Topologically enabled superconductivity: possible implications for rhombohedral graphene
Francesca Paoletti, Daniele Guerci, Giorgio Sangiovanni +2
We present a topological mechanism for superconductivity emerging from Chern-2 insulators. While, naively, time-reversal symmetry breaking is expected to prevent superconductivity,…
Topological Gap Opening without Symmetry Breaking from Dynamical Quantum Correlations
Francesca Paoletti, Laura Fanfarillo, Massimo Capone +1
Topological phase transitions are typically associated with the formation of gapless states. Spontaneous symmetry breaking can lead to a gap opening thereby obliterating the topolo…
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…
