Local spectroscopy of anyons bound to charge traps
Jeong Min Park, Cristian Voinea, Yen-Chen Tsui +7
Fractional quantum Hall states host anyons, emergent quasiparticles with fractional charge and nontrivial exchange statistics. Controlling, trapping, and braiding anyons are centra…
Band mixing and particle-hole asymmetry in moiré fractional Chern insulators
Nicolás Morales-Durán, Jingtian Shi, Cristian Voinea +2
We investigate the effect of remote band mixing on the stability of fractional Chern insulators in a family of models that approximate continuum descriptions of moiré materials. Ou…
Emergence of 3D Superconformal Ising Criticality on the Fuzzy Sphere
Yin Tang, Cristian Voinea, Liangdong Hu +2
Supersymmetric conformal field theories (SCFTs) form a unique subset of quantum field theories which provide powerful insights into strongly coupled critical phenomena. Here, we pr…
Critical Majorana fermion at a topological quantum Hall bilayer transition
Cristian Voinea, Wei Zhu, Nicolas Regnault +1
Quantum Hall bilayers are a uniquely tunable platform that can realize continuous transitions between distinct topological phases of matter. One prominent example is the transition…
Conformal scalar field theory from Ising tricriticality on the fuzzy sphere
Joseph Taylor, Cristian Voinea, Zlatko Papić +1
Free theories are landmarks in the landscape of quantum field theories: their exact solvability serves as a pillar for perturbative constructions of interacting theories. Fuzzy sph…
Regularizing 3D conformal field theories via anyons on the fuzzy sphere
Cristian Voinea, Ruihua Fan, Nicolas Regnault +1
Recently introduced ''fuzzy sphere'' method has enabled accurate numerical regularizations of certain three-dimensional (3D) conformal field theories (CFTs). The regularization is…
Entanglement scaling and charge fluctuations in a Fermi liquid of composite fermions
Cristian Voinea, Songyang Pu, Ajit C. Balram +1
The composite fermion Fermi liquid (CFL) state at filling of a Landau level is a paradigmatic non-Fermi liquid borne out purely by Coulomb interactions. But in what ways is…
Deformed Fredkin model for the Moore-Read state on thin cylinders
Cristian Voinea, Songyang Pu, Ammar Kirmani +3
We propose a frustration-free model for the Moore-Read quantum Hall state on sufficiently thin cylinders with circumferences magnetic lengths. While the Moore-Read Ham…
