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…
Theory of magnetoroton bands in moiré materials
Bishoy M. Kousa, Nicolás Morales-Durán, Tobias M. R. Wolf +2
The recent realization of Hofstadter spectra and fractional Chern insulators in moiré materials has introduced a new ingredient, a periodic lattice potential, to the study of quan…
Anyon superconductivity and plateau transitions in doped fractional quantum anomalous Hall insulators
Pavel A. Nosov, Zhaoyu Han, Eslam Khalaf
Recent experiments reported evidence of superconductivity and re-entrant integer quantum anomalous Hall (RIQAH) insulator upon doping the fractional quantum anomalous…
Higher vortexability: zero field realization of higher Landau levels
Manato Fujimoto, Daniel E. Parker, Junkai Dong +3
The rise of moiré materials has led to experimental realizations of integer and fractional Chern insulators in small or vanishing magnetic fields. At the same time, a set of minim…
Exotic Carriers from Concentrated Topology: Dirac Trions as the Origin of the Missing Spectral Weight in Twisted Bilayer Graphene
Patrick J. Ledwith, Ashvin Vishwanath, Eslam Khalaf
The nature of charge carriers in twisted bilayer graphene (TBG) near , where superconductivity emerges, remains mysterious. While various symmetry-broken ground states have…
