Uncover band topology via quantized drift in two-dimensional Bloch oscillations
Bo Zhu, Shi Hu, Honghua Zhong +1
We propose to measure band topology via quantized drift of Bloch oscillations in a two-dimensional Harper-Hofstadter lattice subjected to tilted fields in both directions. When the…
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…
Stability and collisions of quantum droplets in PT -symmetric dual-core couplers
Zheng Zhou, Bo Zhu, Haibin Wang +1
We study the effect of the interplay between parity-time () symmetry and optical lattice (OL) potential on dynamics of quantum droplets (QDs) forming in a binary boso…
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…
Topological pumping assisted by Bloch oscillations
Yongguan Ke, Shi Hu, Bo Zhu +3
Adiabatic quantum pumping in one-dimensional lattices is extended by adding a tilted potential to probe better topologically nontrivial bands. This extension leads to almost perfec…
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…
Dynamic winding number for exploring band topology
Bo Zhu, Yongguan Ke, Honghua Zhong +1
Topological invariants play a key role in the characterization of topological states. Due to the existence of exceptional points, it is a great challenge to detect topological inva…
Topological Floquet edge states in periodically curved waveguides
Bo Zhu, Honghua Zhong, Yongguan Ke +4
We study the Floquet edge states in arrays of periodically curved optical waveguides described by the modulated Su-Schrieffer-Heeger model. Beyond the bulk-edge correspondence, our…
Floquet control of the gain and loss in a PT-symmetric optical coupler
Yi Wu, Bo Zhu, Shufang Hu +2
Controlling the balanced gain and loss in a PT-symmetric system is a rather challenging task. Utilizing Floquet theory, we explore the constructive role of periodic modulation in c…
