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…
