Emanant and emergent symmetry-topological-order from low-energy spectrum
Zixin Jessie Chen, Ömer M. Aksoy, Cenke Xu +1
Low-energy emanant and emergent symmetries can be anomalous, higher-group, or non-invertible. A way to systematically capture the properties of such symmetries is through the topol…
"Symmetry-from-Anomaly" in Condensed Matter related Constructions
Cenke Xu
The noninvertible axial symmetry constructed from the ABJ-anomaly has attracted enormous interest. We discuss the mechanism of "symmetry-from-anomaly" in condensed matter-related m…
Disorder Operator and Rényi Entanglement Entropy of Symmetric Mass Generation
Zi Hong Liu, Yuan Da Liao, Gaopei Pan +8
In recent years a consensus has gradually been reached that the previously proposed deconfined quantum critical point (DQCP) for spin-1/2 systems, an archetypal example of quantum…
A no-go result for implementing chiral symmetries by locality-preserving unitaries in a 3 dimensional Hamiltonian lattice model of fermions
Lukasz Fidkowski, Cenke Xu
We argue that the chiral symmetry of a Weyl fermion cannot be implemented by a shallow depth quantum circuit operation in a fermionic lattice Hamiltonian model with finite…
Conformal Field Theories generated by Chern Insulators under Quantum Decoherence
Kaixiang Su, Nayan Myerson-Jain, Cenke Xu
We demonstrate that the fidelity between a pure state trivial insulator and the mixed state density matrix of a Chern insulator under decoherence can be mapped to a variety of two-…
Higher-form Symmetries under Weak Measurement
Kaixiang Su, Nayan Myerson-Jain, Chong Wang +2
We aim to address the following question: if we start with a quantum state with a spontaneously broken higher-form symmetry, what is the fate of the system under weak local quantum…
