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…
Theory of Second-Order Topological Superconductors
Zi-Ming Wang, Meng Zeng, Chen Lu +4
Topological superconductors are a class of unconventional superconducting materials featuring sub-gap zero-energy Majorana bound modes that hold promise as a building block for top…
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…
Symmetric Mass Generation in the 1+1 Dimensional Chiral Fermion 3-4-5-0 Model
Meng Zeng, Zheng Zhu, Juven Wang +1
Lattice regularization of chiral fermions has been a long-standing problem in physics. In this work, we present the density matrix renormalization group (DMRG) simulation of the 3-…
Spin-orbit-coupled superconductivity with spin-singlet non-unitary pairing
Meng Zeng, Dong-Hui Xu, Zi-Ming Wang +1
An unconventional superconductor is distinguished with two types of gap functions: unitary and non-unitary. This core subject has been concentrated on purely spin-triplet or single…
Pseudospin-Triplet Pairing in Iron-Chalcogenide Superconductors
Meng Zeng, Dong-Hui Xu, Zi-Ming Wang +2
We study superconductivity of electron systems with both spin and pseudospin-1/2 degrees of freedom. By solving linearized gap equations, we derive a weak coupling criterion for th…
High-order Time-Reversal Symmetry Breaking Normal State
Meng Zeng, Lun-Hui Hu, Hong-Ye Hu +2
Spontaneous time-reversal symmetry breaking plays an important role in studying strongly correlated unconventional superconductors. When two superconducting gap functions with diff…
