Metallogenic quantum criticality: Fermi surface nucleation at transitions between gapped phases
Zhengyan Darius Shi
Continuous quantum phase transitions in interacting many-body systems exhibit universal phenomena that are largely independent of microscopic details. An organizing principle disti…
Skyrmion Fractional Chern Insulator: An Intrinsically Multiband Route to Fractionalization in Rhombohedral Graphene
Julian May-Mann, Tixuan Tan, Patrick J. Ledwith +2
We propose an unconventional microscopic origin for the fractional quantum anomalous Hall (FQAH) effect in rhombohedral graphene moiré superlattices: skyrmion fractionalization. We…

Pavel A. Nosov, Zhengyan Darius Shi
We study transport in lattice composite Fermi liquids realized in half-filled Chern bands with broken inversion symmetry. We show that reduced crystalline symmetry exposes intrinsi…
Superconductivity and non-Fermi liquid metals in a charge-1/3 anyon fluid
Zhengyan Darius Shi, T. Senthil
We revisit the charge-1/3 anyon fluid obtained by doping the Jain fractional Chern insulator (FCI). In the standard composite fermion description, the doped anyons fractio…

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…
Composite Bogoliubov Fermi liquid in a half-filled Chern band
Zhengyan Darius Shi, Pavel A. Nosov
The composite Fermi liquid (CFL) in the half-filled Landau level is a cornerstone of the quantum Hall phase diagram. Recent experiments and numerics indicate that an anomalous comp…
Non-Abelian topological superconductivity from melting Abelian fractional Chern insulators
Zhengyan Darius Shi, T. Senthil
Fractional Chern insulators (FCI) are exotic phases of matter realized at partial filling of a Chern band that host fractionally charged anyon excitations. Recent numerical studies…
Bidirectional ultrafast control of charge density waves via phase competition
Honglie Ning, Kyoung Hun Oh, Yifan Su +17
The intricate competition between coexisting charge density waves (CDWs) can lead to rich phenomena, offering unique opportunities for phase manipulation through electromagnetic st…
Anyon delocalization transitions out of a disordered FQAH insulator
Zhengyan Darius Shi, T. Senthil
Motivated by the experimental discovery of the fractional quantum anomalous Hall (FQAH) effect, we develop a theory of doping-induced transitions out of the lattice Jain s…
Doping lattice non-abelian quantum Hall states
Zhengyan Darius Shi, Carolyn Zhang, T. Senthil
We study quantum phases of a fluid of mobile charged non-abelian anyons, which arise upon doping the lattice Moore-Read quantum Hall state at lattice filling and its gener…
Doping a fractional quantum anomalous Hall insulator
Zhengyan Darius Shi, T. Senthil
We study novel itinerant phases that can be accessed by doping a fractional quantum anomalous Hall (FQAH) insulator, with a focus on the experimentally observed Jain states at latt…
Analytic framework for self-dual criticality in gauge theory with matter
Zhengyan Darius Shi, Arkya Chatterjee
The deconfined phase of 2+1D gauge theory exhibits topological order, with and anyons that have a braiding phase. Proliferating either or driv…
Excitonic quantum criticality: from bilayer graphene to narrow Chern bands
Zhengyan Darius Shi, Hart Goldman, Zhihuan Dong +1
We study a family of excitonic quantum phase transitions describing the evolution of a bilayer metallic state to an inter-layer coherent state where excitons condense. We argue tha…
Controlled expansion for transport in a class of non-Fermi liquids
Zhengyan Darius Shi
Non-Fermi liquids arise when strong interactions destroy stable fermionic quasiparticles. The simplest models featuring this phenomenon involve a Fermi surface coupled to fluctuati…
