Translationally Covariant Modulated Symmetries: Classification and Goldstone
Bo-Ting Chen, Zihan Zhou, Biao Lian
Modulated symmetries are global symmetries with a spatially dependent unit of charge, such as the dipole symmetry and the exponential symmetry. We give the generic condition for a…
Quantum Hilbert Space Fragmentation and Entangled Frozen States
Zihan Zhou, Tian-Hua Yang, Bo-Ting Chen
We find that rank deficiency of the local Hamiltonian in a classically fragmented model is the key mechanism leading to quantum Hilbert space fragmentation. The rank deficiency pro…
Bootstrapping Symmetries in Quantum Many-Body Systems from the Cross Spectral Form Factor
Chen Bai, Zihan Zhou, Bastien Lapierre +1
Symmetries play a central role in quantum many-body physics, yet uncovering them systematically remains challenging. We introduce a bootstrap framework designed to reconstruct the…
Variational quantum algorithm for generalized eigenvalue problems of non-Hermitian systems
Jiaxin Li, Zhaobing Fan, Hongmei Yao +5
Non-Hermitian generalized eigenvalue problems (GEPs) play a significant role in many practical applications, such as mechanical engineering. Based on the generalized Schur decompos…
Quantum Coherence: A Fundamental Resource for Establishing Genuine Multipartite Correlations
Zong Wang, Zhihua Guo, Zhihua Chen +5
We establish the profound equivalence between measures of genuine multipartite entanglement(GME) and their corresponding coherence measures. Initially we construct two distinct cla…
