Neural optimization of the most probable paths of 3D active Brownian particles
Bin Zheng, Zhongqiang Xiong, Changhao Li +7
We develop a variational neural-network framework to determine the most probable path (MPP) of a 3D active Brownian particle (ABP) by directly minimizing the Onsager-Machlup integr…
High Uniformity GaN Micro-pyramids and Platelets by Selective Area Growth
Changhao Li, Vitaly Z. Zubialevich, Peter J. Parbrook +2
The development of uniform GaN micro-pyramids and platelets via selective area growth is a critical step toward advancing III-nitride device technologies, particularly for micro-li…
Des-q: a quantum algorithm to provably speedup retraining of decision trees
Niraj Kumar, Romina Yalovetzky, Changhao Li +2
Decision trees are widely adopted machine learning models due to their simplicity and explainability. However, as training data size grows, standard methods become increasingly slo…
Control incompatibility in multiparameter quantum metrology
Zhiyao Hu, Shilin Wang, Linmu Qiao +6
In practical applications like quantum sensing and quantum imaging, there is often a necessity to estimate multiple parameters simultaneously. Although the ultimate precision limit…
Non-Hermitian Spin-Spin Interaction Mediated by Chiral Phonons
Haowei Xu, Guoqing Wang, Changhao Li +3
Non-Hermiticity and chirality are two fundamental properties known to give rise to various intriguing phenomena. However, the interplay between these properties has been rarely exp…
