Bootstrapping the Quantum Hall problem
Qiang Gao, Ryan A. Lanzetta, Patrick Ledwith +2
The bootstrap method aims to solve problems by imposing constraints on the space of physical observables, which often follow from physical assumptions such as positivity and symmet…
Nonlocal Moments in the Chern Bands of Twisted Bilayer Graphene
Patrick J. Ledwith, Junkai Dong, Ashvin Vishwanath +1
Twisted bilayer graphene (TBG) has elements in common with two paradigmatic examples of strongly correlated physics: quantum Hall physics and Hubbard physics. On one hand, TBG host…
Constraints on real space representations of Chern bands
Qingchen Li, Junkai Dong, Patrick J. Ledwith +1
A Chern band is characterized by a Wannier obstruction indicating the absence of a basis of complete, orthogonal, and exponentially-localized states. Here, we study the properties…
Imaging Coulomb interactions and migrating Dirac cones in twisted graphene by local quantum oscillations
Matan Bocarsly, Indranil Roy, Vishal Bhardwaj +12
Flat band moiré graphene systems have emerged as a quintessential platform to investigate correlated phases of matter. A plethora of interaction-driven ground states have been prop…
Superfluid stiffness of twisted multilayer graphene superconductors
Abhishek Banerjee, Zeyu Hao, Mary Kreidel +12
The robustness of the macroscopic quantum nature of a superconductor can be characterized by the superfluid stiffness, , a quantity that describes the energy required to vary…
Strong interactions and isospin symmetry breaking in a supermoiré lattice
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +10
In multilayer moiré heterostructures, the interference of multiple twist angles ubiquitously leads to tunable ultra-long-wavelength patterns known as supermoiré lattices. However,…
