Conformal Data for the Wilson-Fisher CFT in -Dimensional Spacetime from Exact Diagonalization and Matrix Product States on the Fuzzy Sphere
Arjun Dey, Loic Herviou, Christopher Mudry +2
We study at zero temperature a microscopic quantum spin-1 model on the fuzzy sphere that realizes the Wilson-Fisher conformal field theory (CFT) in -dimensional space…

Conformal Data for the O(3) Wilson-Fisher Conformal Field Theory from Fuzzy Sphere Realization of the Quantum Rotor Model
Arjun Dey, Loic Herviou, Christopher Mudry +1
We present a model for strongly interacting fermions with internal O(3) symmetry on the fuzzy-sphere that (i) preserves the rotational symmetry of the fuzzy sphere and (ii) undergo…

A Novel Perspective on Ideal Chern Bands with Strong Short-Range Repulsion: Applications to Correlated Metals, Superconductivity, and Topological Order
Patrick H. Wilhelm, Andreas M. Läuchli, Mathias S. Scheurer
Motivated by recent experiments on correlated van der Waals materials, including twisted and rhombohedral graphene and twisted WSe, we perform an analytical and numerical study…
