Monte Carlo Studies of Twisted Bilayer Graphene: Strain and Thermal Fluctuations
Johannes S. Hofmann, Patrick Ledwith, Ashvin Vishwanath +2
We study the phase diagram of twisted bilayer graphene at charge neutrality as a function of twist angle , uniaxial heterostrain , and temperature using sign-p…
Single-component twisted orthogonal metal in an -anyon fluid
Zhaoyu Han, Ashvin Vishwanath, Eslam Khalaf
The paper proposes a new metallic phase that appears when a 1/3 fractional Chern insulator is doped, featuring a Fermi surface of emergent charge‑e/3 fermions coupled to a twisted…
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…
Anyon superfluidity of excitons in quantum Hall bilayers
Zhaoyu Han, Taige Wang, Zhihuan Dong +2
The charged anyons of a fractional quantum Hall fluid are necessarily dispersionless due to the continuous magnetic translation symmetry. Neutral anyons, however, can disperse, res…
Crystals Caught Doping: Metallic Wigner Crystals in Rhombohedral Graphene
Junkai Dong, Tomohiro Soejima, Daniel E. Parker +1
Nearly a century after Wigner's initial proposal, electron crystals are now a topic of intense experimental and theoretical interest. However, most proposed crystalline phases are…
Charge- superconductor with parafermionic vortices: A path to universal topological quantum computation
Zhengyan Darius Shi, Zhaoyu Han, Srinivas Raghu +1
Topological superconductors (TSCs) provide a promising route to fault-tolerant quantum information processing. However, the canonical Majorana platform based on TSCs remains c…
