Occupation-selective topological pumping from Floquet gauge fields
Wenjie Liu, Ching Hua Lee, Zhoutao Lei
Topological pumping is conventionally governed by single-particle band topology. Here we show that promoting tunneling to a dynamical, occupation-conditioned variable fundamentally…
Localization and scattering of a photon in quasiperiodic qubit arrays
Xinyin Zhang, Yongguan Ke, Zhengzhi Peng +4
We study the localization and scattering of a single photon in a waveguide coupled to qubit arrays with quasiperiodic spacings. As the quasiperiodic strength increases, localized s…
Heisenberg-limited Frequency Estimation via Driving through Quantum Phase Transitions
Min Zhuang, Hongtao Huo, Yuxiang Qiu +3
High-precision frequency estimation is an ubiquitous issue in fundamental physics and a critical task in spectroscopy. Here, we propose a quantum Ramsey interferometry to realize h…
Edge states in quantum spin chains: the interplay among interaction, gradient magnetic field and Floquet engineering
Wenjie Liu, Bo Zhu, Li Zhang +2
We explore the edge defects induced by spin-spin interaction in a finite paradigmatic Heisenberg spin chain. By introducing a gradient magnetic field and a periodically-modulated s…
Mobility edge of Stark many-body localization
Li Zhang, Yongguan Ke, Wenjie Liu +1
We investigate many-body localization of interacting spinless fermions in a one-dimensional disordered and tilted lattice. The fermions undergo energy-dependent transitions from er…
Quantum metrology via chaos in a driven Bose-Josephson system
Wenjie Liu, Min Zhuang, Bo Zhu +2
Entanglement preparation and signal accumulation are essential for quantum parameter estimation, which pose significant challenges to both theories and experiments. Here, we propos…
