From eigenstate thermalization to hydrodynamic transport in correlated metals
Yochai Werman, Shubhayu Chatterjee, Ehud Altman
We present a new framework for computing low frequency transport properties of strongly correlated, ergodic systems. Our main assumption is that, when a thermalizing diffusive syst…
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…
Enhanced thermal Hall effect in the square-lattice Néel state
Rhine Samajdar, Mathias S. Scheurer, Shubhayu Chatterjee +3
Recent experiments on several cuprate compounds have identified an enhanced thermal Hall response in the pseudogap phase. Most strikingly, this enhancement persists even in the und…
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…
