Anatomy of Z2 fluxes in anyon Fermi liquids and Bose condensates
Oscar Pozo, Peng Rao, Chuan Chen +1
We study in detail the properties of pi-fluxes embedded in a state with a finite density of anyons that form either a Fermi liquid or a Bose-Einstein condensate. By employing a rec…
Competition of Spinon Fermi Surface and Heavy Fermi Liquids states from the Periodic Anderson to the Hubbard model
Chuan Chen, Inti Sodemann, Patrick A. Lee
We study a model of correlated electrons coupled by tunnelling to a layer of itinerant metallic electrons, which allows to interpolate from a frustrated limit favorable to spin liq…
Correlated states of a triangular net of coupled quantum wires: Implications for the phase diagram of marginally twisted bilayer graphene
Chuan Chen, A. H. Castro Neto, Vitor M. Pereira
We explore in detail the electronic phases of a system consisting of three non-colinear arrays of coupled quantum wires, each rotated 120 degrees with respect to the next. A pertur…
Antiferromagnetism and chiral d-wave superconductivity from an effective model for twisted bilayer graphene
Xingyu Gu, Chuan Chen, Jia Ning Leaw +4
Starting from the strong-coupling limit of an extended Hubbard model, we develop a spin-fermion theory to study the insulating phase and pairing symmetry of the superconducting pha…
Discommensuration-enhanced superconductivity in the charge density wave phases of transition-metal dichalcogenides
Chuan Chen, Lei Su, A. H. Castro Neto +1
We introduce a McMillan-Ginzburg-Landau theory to describe the cooperative coexistence of charge-density and superconducting order in two-dimensional crystals. With a free-energy t…
Anomalous quantum metal in a 2D crystalline superconductor with intrinsic electronic non-uniformity
Linjun Li, Chuan Chen, Kenji Watanabe +6
The details of the superconducting to quantum metal transition (SQMT) at T=0 are an open problem that invokes much interest in the nature of this exotic and unexpected ground state…
