Quantum Hall Antidot as a Fractional Coulombmeter
Mario Di Luca, Emily Hajigeorgiou, Zekang Zhou +6
The detection of fractionally charged quasiparticles, which arise in the fractional quantum Hall regime, is of fundamental importance for probing their exotic quantum properties. W…
Putting a new spin on the incommensurate Kekulé spiral: from spin-valley locking and collective modes to fermiology and implications for superconductivity
Ziwei Wang, Glenn Wagner, Yves H. Kwan +3
We revisit the global phase diagram of magic-angle twisted bilayer and [symmetric] trilayer graphene (MA-TBG/TSTG) in light of recent scanning tunneling microscopy (STM) measuremen…
Majorana edge reconstruction and the non-Abelian thermal Hall puzzle
Tevž Lotrič, Taige Wang, Michael P. Zaletel +2
Pioneering thermal transport measurements on two-dimensional electron gases in high magnetic fields have demonstrated that the quantized Hall state at filling factor has a…
Fractional Chern Insulators and Competing States in a Twisted MoTe Lattice Model
Yuchi He, S. H. Simon, S. A. Parameswaran
We construct an interacting lattice model for twisted bilayers at a twist angle of approximately 3.7\degree. We use the infinite density matrix renormalization…
A Closed Band-Projected Density Algebra Must be Girvin-MacDonald-Platzman
Ziwei Wang, Steven H. Simon
The band-projected density operators in a Landau level obey the Girvin-MacDonald-Platzman (GMP) algebra, and a large amount of effort in the study of fractional Chern insulators ha…
