Diffusion-Driven Inter-Outer Surface Separation for Point Clouds with Open Boundaries
Zhengyan Qin, Liyuan Qiu
We propose a diffusion-based algorithm for separating the inter and outer layer surfaces from double-layered point clouds, particularly those exhibiting the "double surface artifac…
Probing the hollowing transition of a shell-shaped BEC with collective excitation
Zerong Huang, Kai Yuen Lee, Chun Kit Wong +4
We investigate the hollowing transition of a shell-shaped Bose-Einstein condensate using collective excitations. The shell is created using an immiscible dual-species BEC mixture,…
Expansion dynamics of a shell-shaped Bose-Einstein condensate
Fan Jia, Zerong Huang, Liyuan Qiu +3
Bose-Einstein condensates (BECs) confined on shell-shaped surfaces have been proposed as a platform for exploring many nontrivial quantum phenomena on curved spaces. However, as th…
Observation of topological Euler insulators with a trapped-ion quantum simulator
W. -D. Zhao, Y. -B. Yang, Y. Jiang +9
Symmetries play a crucial role in the classification of topological phases of matter. Although recent studies have established a powerful framework to search for and classify topol…
Observation of heat scaling across a first-order quantum phase transition in a spinor condensate
Haiyu Liang, Liyuan Qiu, Yanbin Yang +4
Heat generated as a result of the breakdown of an adiabatic process is one of the central concepts of thermodynamics. In isolated systems, the heat can be defined as an energy incr…
Observation of Dynamical Quantum Phase Transition with Correspondence in Excited State Phase Diagram
T. Tian, H. -X. Yang, L. -Y. Qiu +4
Dynamical quantum phase transitions are closely related to equilibrium quantum phase transitions for ground states. Here, we report an experimental observation of a dynamical quant…
Observation of generalized Kibble-Zurek mechanism across a first-order quantum phase transition in a spinor condensate
L. -Y. Qiu, H. -Y. Liang, Y. -B. Yang +4
The Kibble-Zurek mechanism provides a unified theory to describe the universal scaling laws in the dynamics when a system is driven through a second-order quantum phase transition.…
