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…
