Fermionic Villain model with exact lattice chiral symmetries
Zhiyao Lu, Shu-Heng Shao
We present a fermionic lattice Hamiltonian that exactly realizes the global symmetry and the associated chiral anomalies o…
Lattice chiral symmetry from bosons in 3+1d
Zhiyao Lu, Sahand Seifnashri, Shu-Heng Shao
We present a solvable Hamiltonian that realizes an exact lattice chiral symmetry. Nielsen-Ninomiya-type no-go theorems are evaded by using lattice bosons rat…
Towards High-Brightness Perfect Photon Blockade
Zhi-Guang Lu, Xin-You Lü
Single-photon sources with high single-photon purity and high brightness are key elements of many future quantum technologies. While photon blockade (PB) is widely exploited in the…
Decoherence-free Behaviors of Quantum Emitters in Dissipative Photonic Graphene
Qing-Yang Qiu, Guoqing Tian, Zhi-Guang Lu +2
Achieving decoherence-free quantum state manipulation is a paramount goal in modern quantum technologies. To this end, we demonstrate its implementation in a two-dimensional dissip…
Operator Spreading and Information Propagation: Equivalence and Beyond
Cheng Shang, Zhi-Guang Lu, Hayato Kinkawa +1
We investigate the quantitative relationship between operator spreading and classical information propagation in quantum systems. Focusing on a bi-partite quantum channel, we deriv…
Higher-Order Exceptional Points Induced by Non-Markovian Environments
H. Z. Shen, X. C. Zhang, L. Y. Ning +3
Exceptional points (EPs) are central to non-Hermitian physics because of their unique properties and broad application prospects. While extensively studied in parity-time ($\mathca…
