Topological heavy fermions in magnetic field
Keshav Singh, Aaron Chew, Jonah Herzog-Arbeitman +2
The recently introduced topological heavy fermion model (THFM) provides a means for interpreting the low-energy electronic degrees of freedom of the magic angle twisted bilayer gra…
Many-Body Superconductivity in Topological Flat Bands
Jonah Herzog-Arbeitman, Aaron Chew, Kukka-Emilia Huhtinen +2
In a flat band superconductor, bosonic excitations can disperse while unpaired electrons are immobile. To study this strongly interacting system, we construct a family of multi-ban…
Reentrant Correlated Insulators in Twisted Bilayer Graphene at 25T ( Flux)
Jonah Herzog-Arbeitman, Aaron Chew, Dmitri K. Efetov +1
Twisted bilayer graphene (TBG) is remarkable for its topological flat bands, which drive strongly-interacting physics at integer fillings, and its simple theoretical description fa…
Observation of re-entrant correlated insulators and interaction driven Fermi surface reconstructions at one magnetic flux quantum per moiré unit cell in magic-angle twisted bilayer graphene
Ipsita Das, Cheng Shen, Alexandre Jaoui +8
The discovery of flat bands with non-trivial band topology in magic angle twisted bi-layer graphene (MATBG) has provided a unique platform to study strongly correlated phe-nomena i…
Fermionized parafermions and symmetry-enriched Majorana modes
Aaron Chew, David F. Mross, Jason Alicea
Parafermion zero modes are generalizations of Majorana modes that underlie comparatively rich non-Abelian-anyon properties. We introduce exact mappings that connect parafermion cha…
