Colloidal Directional Structures at a Nematic Liquid Crystal-Air Interface
Nan Wang, Julian Evans, Chenxi Li +2
We present a variety of structures formed by colloidal droplets at a nematic liquid crystal-air interface, where the elastic dipole-dipole, quadrupole-quadrupole, and dipole-quadru…
Multi-AI competing and winning against humans in iterated Rock-Paper-Scissors game
Lei Wang, Wenbin Huang, Yuanpeng Li +2
Predicting and modeling human behavior and finding trends within human decision-making processes is a major problem of social science. Rock Paper Scissors (RPS) is the fundamental…
Inhomogeneity-Induced Casimir Transport of Nanoparticles
F. Bao, K. Shi, G. Cao +2
This letter proposes a scheme for transporting nanoparticles immersed in a fluid, relying on quantum vacuum fluctuations. The mechanism lies in the inhomogeneity-induced lateral Ca…
Quantum propulsion and trapping of nano-objects by inhomogeneity-induced lateral Casimir forces
F. Bao, K. Shi, S. He
Lateral Casimir force near a laterally-inhomogeneous plate is first revealed by both rigorous simulations and proximity approximations. The inhomogeneity-induced lateral Casimir fo…
Optical manipulation of shape-morphing elastomeric liquid crystal microparticles doped with gold nanocrystals
Yaoran Sun, Julian S. Evans, Taewoo Lee +4
We demonstrate facile optical manipulation of shape of birefringent colloidal microparticles made from liquid crystal elastomers. Using soft lithography and polymerization, we fabr…
Active shape-morphing elastomeric colloids in short-pitch cholesteric liquid crystals
Julian S. Evans, Yaoran Sun, Bohdan Senyuk +4
Active elastomeric liquid crystal particles with initial cylindrical shapes are obtained by means of soft lithography and polymerization in a strong magnetic field. Gold nanocrysta…
Shape-dependent oriented trapping and scaffolding of plasmonic nanoparticles by topological defects for self-assembly of colloidal dimers in liquid crystals
Bohdan Senyuk, Julian S. Evans, Paul J. Ackerman +6
We demonstrate scaffolding of plasmonic nanoparticles by topological defects induced by colloidal microspheres to match their surface boundary conditions with a uniform far-field a…
Inhomogeneity-related cutoff dependence of the Casimir energy and stress
F. Bao, J. S. Evans, M. Fang +1
The cutoff dependence of the Casimir energy and stress is studied using the Green's function method for a system that is piecewise-smoothly inhomogeneous along one dimension. The a…
