Electrostatic effects of the MnBi2Te4-superconductor hetero-structures in chiral Majorana search
Li Chen, Zhan Cao, Ke He +2
The realization of chiral Majorana modes is a challenging task. We aim to comprehend the phase diagrams and parameter control capabilities of the actual devices used in the chiral…
Machine learning phases of active matter
Tingting Xue, Xu Li, Xiaosong Chen +2
Recent years have witnessed a growing interest in using machine learning to predict and identify phase transitions in various systems. Here we adopt convolutional neural networks (…
A Simple Framework for Finding Balanced Sparse Cuts via APSP
Li Chen, Rasmus Kyng, Maximilian Probst Gutenberg +1
We present a very simple and intuitive algorithm to find balanced sparse cuts in a graph via shortest-paths. Our algorithm combines a new multiplicative-weights framework for solvi…
Coexistence Designs of Radar and Communication Systems in a Multi-path Scenario
Haoyu Zhang, Li Chen, Kaifeng Han +2
The focus of this study is on the spectrum sharing between multiple-input multiple-output (MIMO) communications and co-located MIMO radar systems in multi-path environments. The ma…
Cramér-Rao Bounds of Near-Field Positioning Based on Electromagnetic Propagation Model
Ang Chen, Li Chen, Yunfei Chen +3
The adoption of large-scale antenna arrays at high-frequency bands is widely envisioned in the beyond 5G wireless networks. This leads to the near-field regime where the wavefront…
Maximum Flow and Minimum-Cost Flow in Almost-Linear Time
Li Chen, Rasmus Kyng, Yang P. Liu +3
We give an algorithm that computes exact maximum flows and minimum-cost flows on directed graphs with edges and polynomially bounded integral demands, costs, and capacities in…
