Optimizing circular rotations in confined systems via enhanced self-driven speed of active nematics
《Communications in Theoretical Physics》2025年第3期157-164,共8页Tian Tang Chun-lai Ren Yu-qiang Ma 
supported by the National Key Research and Development Program of China under Grant No.2022YFA1405000;Innovation Program for Quantum Science and Technology under Grant No.2024ZD0300101;the National Natural Science Foundation of China under Grant Nos.12274212,12174184,12347102。
Active matter exhibits collective motions at various scales.Geometric confinement has been identified as an effective way to control and manipulate active fluids,with much attention given to external factors.However,t...
