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…
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…
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…
