Parity Anomaly as Modular Commutator with Massless Dirac Fermion
Meng Zeng
The modular commutator extracts the chiral central charge from a single bulk wavefunction of a \emph{gapped} 2d state, where $3J/π…
Universal Dynamic Scaling of 2D Quantum Ising Transition on the Fuzzy Sphere
Meng Zeng, Shuai Yin, Roderich Moessner
We revisit the problem of \textit{real-time} quantum dynamics of the paradigmatic two dimensional transverse-field Ising model using the recently developed fuzzy sphere regularizat…
Optical Conductivity in Symmetric Mass Generation Insulators
Meng Zeng, Fu Xu, Da-Chuan Lu +1
Symmetric mass generation (SMG) insulators are interaction-driven, featureless Mott insulating states in quantum many-body fermionic systems. Recent advancements suggest that zeros…
Gapless symmetry-protected topological phases and generalized deconfined critical points from gauging a finite subgroup
Lei Su, Meng Zeng
Gauging a finite subgroup of a global symmetry can map conventional phases and phase transitions to unconventional ones. In this work, we study, as a concrete example, an emergent…
Green's Function Zeros in Fermi Surface Symmetric Mass Generation
Da-Chuan Lu, Meng Zeng, Yi-Zhuang You
The Fermi surface symmetric mass generation (SMG) is an intrinsically interaction-driven mechanism that opens an excitation gap on the Fermi surface without invoking symmetry-break…
Fermi Surface Symmetric Mass Generation
Da-Chuan Lu, Meng Zeng, Juven Wang +1
Symmetric mass generation is a novel mechanism to give gapless fermions a mass gap by non-perturbative interactions without generating any fermion bilinear condensation. The previo…
