Spin-Selective Spectral Flattening and Wave-Packet Dynamics in a Flux-Engineered Lieb Lattice
Nana Chang, Xiaoji Zhou, Yanglin Zhou +1
We investigate reversible internal-state-selective wave-packet transport induced by spin-dependent Peierls phases in a two-dimensional nearest-neighbor Lieb lattice. The two conser…

Magnetic Field Induced Band Deformation in a Lieb Lattice:Aharonov-Bohm Caging and Zeeman Splitting
Nana Chang, Xiaoji Zhou
Flat-band systems are highly sensitive to external perturbations, providing a route to study unconventional localization, transport, and spin physics. Lieb lattice, a two-dimension…

Influence of thermal effects on atomic Bloch oscillation
Guoling Yin, Chi-Kin Lai, Nana Chang +3
Advancements in the experimental toolbox of cold atoms have enabled the meticulous control of atomic Bloch oscillation within optical lattices, thereby enhancing the capabilities o…
