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…
Energetics of Pfaffian-AntiPfaffian Domains
Steven H. Simon, Matteo Ippoliti, Michael P. Zaletel +1
In several recent works it has been proposed that, due to disorder, the experimentally observed nu=5/2 quantum Hall state could be microscopically composed of domains of Pfaffian o…
Local Matrix Product Operators: Canonical Form, Compression, & Control Theory
Daniel E. Parker, Xiangyu Cao, Michael P. Zaletel
We present a new method for compressing matrix product operators (MPOs) which represent sums of local terms, such as Hamiltonians. Just as with area law states, such local operator…
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…
Glide-resolved photoemission spectroscopy: Measuring topological invariants in nonsymmorphic space groups
A. Alexandradinata, Zhijun Wang, B. Andrei Bernevig +1
The two classes of 3D, time-reversal-invariant insulators are known to subdivide into four classes in the presence of glide symmetry. Here, we extend this classification of insulat…
Isometric Tensor Network States in Two Dimensions
Michael P. Zaletel, Frank Pollmann
Tensor network states (TNS) are a promising but numerically challenging tool for simulating two-dimensional (2D) quantum many-body problems. We introduce an isometric restriction o…
The gate-tunable strong and fragile topology of multilayer-graphene on a transition metal dichalcogenide
Michael P. Zaletel, Jun Yong Khoo
We analyze the phase diagram of multilayer-graphene sandwiched between identical transition metal dichalcogenides. Recently realized in all van-der-Wall heterostructures, these san…
Spin-orbit driven band inversion in bilayer graphene by van der Waals proximity effect
J. O. Island, X. Cui, C. Lewandowski +10
Spin orbit coupling (SOC) is the key to realizing time-reversal invariant topological phases of matter. Famously, SOC was predicted by Kane and Mele to stabilize a quantum spin Hal…
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…
