Escaping the Composite Fermi Sea: An Incompressible State at Half Filling in Graphene's Lowest Landau Level
Domagoj Perkovic, Ziwei Wang, Steven Herbert Simon
Recent experiments in monolayer and trilayer graphene have observed incompressible even-denominator fractional quantum Hall states within narrow regions of parameter space associat…
Symmetry and Quantum Geometry in Bloch Bands
Ziwei Wang, Charlie Raca, Steven H. Simon
Quantum geometric quantities have featured heavily in the discussion of the properties of quantum systems in recent years. Among quantities most commonly discussed is the variance…
Meta-cavity Quantum Electrodynamics
Xueshi Li, Ziwei Wang, Yan Chen +13
Cavity quantum electrodynamics (cQED) harnesses light-matter interactions to produce nonclassical light states. However, a fundamental challenge lies in simultaneously achieving Pu…
Mean-field Modelling of Moiré Materials: A User's Guide with Selected Applications to Twisted Bilayer Graphene
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We review the theoretical modelling of moiré materials, focusing on various aspects of magic-angle twisted bilayer graphene (MA-TBG) viewed through the lens of Hartree-Fock mean-fi…
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…
Nearfield Vortex Dynamics of Supercell Bloch Modes
Xiaona Ye, Guangfeng Wang, Xiaoyang Duan +7
Densely arranged optical vortices are natural solutions of high-symmetry Bloch modes in photonic crystals. However, strict symmetry constraints limit the potential spatial configur…
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…
Textured Exciton Insulators
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We introduce and study new interacting topological states that arise in time-reversal symmetric bands with an underlying obstruction to forming localized states. If the vall…
Chern-Textured Exciton Insulators with Valley Spiral Order in Moiré Materials
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We explore the phase diagrams of moiré materials in search of a new class of intervalley-coherent correlated insulating state: the Chern texture insulator (CTI). This phase of matt…
Double-dome Unconventional Superconductivity in Twisted Trilayer Graphene
Zekang Zhou, Jin Jiang, Paritosh Karnatak +8
Graphene moiré systems are ideal environments for investigating complex phase diagrams and gaining fundamental insights into the mechanisms underlying exotic states of matter, as t…
Kekulé spirals and charge transfer cascades in twisted symmetric trilayer graphene
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We study the phase diagram of magic-angle twisted symmetric trilayer graphene in the presence of uniaxial heterostrain and interlayer displacement field. For experimentally reasona…
