Numerical identification and gapped boundaries of abelian fermionic topological order
Nick Bultinck
In this work we consider general fermion systems in two spatial dimensions, both with and without charge conservation symmetry, which realize a nontrivial fermionic topological ord…
Ground State and Hidden Symmetry of Magic Angle Graphene at Even Integer Filling
Nick Bultinck, Eslam Khalaf, Shang Liu +3
In magic angle twisted bilayer graphene, electron-electron interactions play a central role resulting in correlated insulating states at certain integer fillings. Identifying the n…
Isometric Tensor Network representation of string-net liquids
Tomohiro Soejima, Karthik Siva, Nick Bultinck +3
Recently, a class of tensor networks called isometric tensor network states (isoTNS) was proposed which generalizes the canonical form of matrix product states to tensor networks i…
Symmetry breaking and skyrmionic transport in twisted bilayer graphene
Shubhayu Chatterjee, Nick Bultinck, Michael P. Zaletel
Motivated by recent low-temperature magnetoresistance measurements in twisted bilayer graphene aligned with hexagonal Boron Nitride substrate, we perform a systematic study of poss…
A UV perspective on mixed anomalies at critical points between bosonic symmetry-protected phases
Nick Bultinck
Symmetry-protected phases are gapped phases of matter which are distinguished only in the presence of a global symmetry G. These quantum phases lack any symmetry-breaking or topolo…
A mechanism for anomalous Hall ferromagnetism in twisted bilayer graphene
Nick Bultinck, Shubhayu Chatterjee, Michael P. Zaletel
We use a lowest Landau level model to study the recent observation of an anomalous Hall effect in twisted bilayer graphene. This effective model is rooted in the occurrence of Cher…
