Time crystalline solitons and their stochastic dynamics in a driven-dissipative Ï^4 model
Xingdong Luo, Zhizhen Chen
Periodically driven systems provide unique opportunities to investigate the dynamics of topological excitations far from equilibrium. In this paper, we report a time-crystalline so…

Generalizable Targeted Data Poisoning against Varying Physical Objects
Zhizhen Chen, Zhengyu Zhao, Subrat Kishore Dutta +3
Targeted data poisoning (TDP) aims to compromise the model's prediction on a specific (test) target by perturbing a small subset of training data. Existing work on TDP has focused…
