Activity-assisted barrier-crossing of self-propelled colloids over parallel microgrooves
Yan Wen, Zhihao Li, Haiqin Wang +5
We report a systematic study of the dynamics of self-propelled particles (SPPs) over a one-dimensional periodic potential landscape, which is fabricated on a microgroove-patterned…
Dynamics of flexible fibers in confined shear flows at finite Reynolds numbers
Jian Su, Kun Ma, Zhongyu Yan +2
We carry out a numerical study on the dynamics of a single non-Brownian flexible fiber in two-dimensional Couette flows at finite Reynolds numbers. We employ the bead-spring model…
Spontaneous Bending of Hydra Tissue Fragments Driven by Supracellular Actomyosin Bundles
Jian Su, Haiqin Wang, Zhongyu Yan +1
Hydra tissue fragments excised freshly from Hydra body bend spontaneously to some quasi-stable shape in several minutes. We propose that the spontaneous bending is driven mechanica…
Variational approximation method for the long-range force transmission in biopolymer gels
Haiqin Wang, Xinpeng Xu
The variational principle of minimum free energy (MFEVP) has been widely used in the study of soft matter statics. MFEVP can be used not only to derive equilibrium equations (inclu…
Variational methods and deep Ritz method for active elastic solids
Haiqin Wang, Boyi Zou, Jian Su +2
Variational methods have been widely used in soft matter physics for both static and dynamic problems. These methods are mostly based on two variational principles: the variational…
