Super-Heisenberg scaling in a triple point criticality
Jia-Ming Cheng, Yong-Chang Zhang, Xiang-Fa Zhou +1
We investigate quantum-enhanced metrology in a triple point criticality and discover that quantum criticality can not always enhance measuring precision. We have developed suitable…
Learning Nonlinear Waves in Plasmon-induced Transparency
Jiaxi Cheng, Zhenhao Cen, Siliu Xu
Plasmon-induced transparency (PIT) displays complex nonlinear dynamics that find critical phenomena in areas such as nonlinear waves. However, such a nonlinear solution depends sen…
Bose-Einstein condensates in an atom-optomechanical system with effective global non-uniform interaction
Jia-Ming Cheng, Zheng-Wei Zhou, Guang-Can Guo +2
We consider a hybrid atom-optomechanical system consisting of a mechanical membrane inside an optical cavity and an atomic Bose-Einstein condensate outside the cavity. The condensa…
Region crossing change on surfaces
Jiawei Cheng, Zhiyun Cheng, Jinwen Xu +1
Region crossing change is a local operation on link diagrams. The behavior of region crossing change on is well understood. In this paper, we study the behavior of (modified)…
Topological spinor vortex matter on spherical surface induced by non-Abelian spin-orbital-angular-momentum coupling
Jia-Ming Cheng, Ming Gong, Guang-Can Guo +2
We provide an explicit way to implement non-Abelian spin-orbital-angular-momentum (SOAM) coupling in spinor Bose-Einstein condensates using magnetic gradient coupling. For a spheri…
Symmetry-enriched Bose-Einstein condensates in spin-orbit coupled bilayer system
Jia-Ming Cheng, Xiang-Fa Zhou, Zheng-Wei Zhou +2
We consider the fate of Bose-Einstein condensation (BEC) with time-reversal symmetry and inversion symmetry in a spin-orbit coupled bilayer system. When these two symmetry operator…
Exact scaling of geometric phase and fidelity susceptibility and their breakdown across the critical points
Jia-Ming Cheng, Ming Gong, Guang-Can Guo +1
It was shown via numerical simulations that geometric phase (GP) and fidelity susceptibility (FS) in some quantum models exhibit universal scaling laws across phase transition poin…
