Synthesizing Arbitrary Non-Hermitian Hamiltonian with Stochastic Floquet Engineering
Lingzhen Guo, Hui Jing
The conventional Floquet engineering scheme synthesizes a given target Hamiltonian with a deterministic temporal periodic driving field. In this work, we introduce the stochastic F…
Selective high-order topological states and tunable chiral emission in atomic metasurfaces
Yi-Xin Wang, Yan Zhang, Lei Du +2
Atomic metasurfaces (AMs) provide a powerful nanophotonic platform for integrating topological effects into quantum many-body systems. In this Letter, we investigate the quantum op…
Quantum dissipative dynamics of driven Duffing oscillator near attractors
Wei Feng, Lingzhen Guo
We investigate the quantum dissipative dynamics near the stable states (attractors) of a driven Duffing oscillator. A refined perturbation theory that can treat two perturbative pa…
Engineering Bosonic Codes with Quantum Lattice Gates
Lingzhen Guo, Tangyou Huang, Lei Du
Bosonic codes offer a hardware-efficient approach to encoding and protecting quantum information with a single continuous-variable bosonic system. In this paper, we introduce a new…
Perturbative Framework for Engineering Arbitrary Floquet Hamiltonian
Yingdan Xu, Lingzhen Guo
We develop a systematic perturbative framework to engineer an arbitrary target Hamiltonian in the Floquet phase space of a periodically driven oscillator based on Floquet-Magnus ex…
Chirality, Nonreciprocity and Symmetries for a Giant Atom
Luting Xu, Lingzhen Guo
Chiral and nonreciprocal quantum devices are crucial for signal routing and processing in a quantum network. In this work, we study the chirality and nonreciprocity of a giant atom…
