Drag-induced skin effect in a Bose-Fermi mixture
Wenjie Liu, Ching Hua Lee, Yee Sin Ang +1
The non-Hermitian skin effect (NHSE) represents one of the most distinctive phenomena in non-Hermitian physics. Here, we uncover a new drag-induced NHSE mechanism in interacting Bo…
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…
Shortcuts to adiabatic Thouless pumping
Wenjie Liu, Yongguan Ke, Chaohong Lee
Thouless pumping, the quantized transport of particles in a cyclic adiabatic evolution, faces a challenge: slow driving may exceed the coherent time, while fast driving may break q…
Topological pumping induced by spatiotemporal modulation of interaction
Boning Huang, Yongguan Ke, Wenjie Liu +1
Particle-particle interaction provides a new degree of freedom to induce novel topological phenomena. Here, we propose to use spatiotemporal modulation of interaction to realize to…
Topological inverse band theory in waveguide quantum electrodynamics
Yongguan Ke, Jiaxuan Huang, Wenjie Liu +2
Topological phases play a crucial role in the fundamental physics of light-matter interaction and emerging applications of quantum technologies. However, the topological band theor…
Correlated topological pumping of interacting bosons assisted by Bloch oscillations
Wenjie Liu, Shi Hu, Li Zhang +2
Thouless pumping, not only achieving quantized transport but also immune to moderate disorder, has attracted growing attention in both experiments and theories. Here, we explore ho…
Magnon boundary states tailored by longitudinal spin-spin interactions and topology
Wenjie Liu, Yongguan Ke, Zhoutao Lei +1
Since longitudinal spin-spin interaction is ubiquitous in magnetic materials, it is very interesting to explore the interplay between topology and longitudinal spin-spin interactio…
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…
Floquet-surface bound states in the continuum in a resonantly driven 1D tilted defect-free lattice
Bo Zhu, Yongguan Ke, Wenjie Liu +2
We study the Floquet-surface bound states embedded in the continuum (BICs) and bound states out the continuum (BOCs)in a resonantly driven 1D tilted defect-free lattice. In contras…
Modulation-induced long-range magnon bound states in one-dimensional optical lattices
Wenjie Liu, Yongguan Ke, Bo Zhu +1
Ultracold two-level atoms in optical lattices offer an excellent experimental platform to explore magnon excitations [Fukuhara et al 2013 Nat. Phys. 9, 235; Fukuhara et al 2013 Nat…
