Floquet Higher-Order Topological Insulators with Anomalous Dynamical Polarization
Biao Huang, W. Vincent Liu
Higher order topological insulators (HOTI) have emerged as a new class of phases, whose robust in-gap "corner" modes arise from the bulk higher-order multipoles beyond the dipoles…

Scrambling dynamics and many-body chaos in a random dipolar spin model
Ahmet Keles, Erhai Zhao, W. Vincent Liu
Is there a quantum many-body system that scrambles information as fast as a black hole? The Sachev-Ye-Kitaev model can saturate the conjectured bound for chaos, but it requires ran…

Observation of phonon parametric down-conversion in a spherical Bose-Einstein condensate
Tianyou Gao, Jian-Song Pan, Dongfang Zhang +8
We report the observation of parametric down-conversion of phonons in a spherical Bose-Einstein condensate. The spherical symmetry, which is crucial for observing this phenomenon,…
