Collective motion of active particles exhibiting non-reciprocal orientational interactions
Milos Knezevic, Till Welker, Holger Stark
We present a Brownian dynamics study of a 2d bath of active particles interacting among each other through usual steric interactions and, additionally, via non-reciprocal avoidant…
Oscillatory active microrheology of active suspensions
M. Knezevic, L. E. Aviles Podgurski, H. Stark
Using the method of Brownian dynamics, we investigate the dynamic properties of a 2d suspension of active disks at high Péclet numbers using active microrheology. In our simulation…
Effective Langevin equations for a polar tracer in an active bath
Milos Knezevic, Holger Stark
We study a polar tracer, having a concave surface, immersed in a two-dimensional suspension of active particles. Using Brownian dynamics simulations, we measure the distributions a…
Surface Tensions between Active Fluids and Solid Interfaces: bare vs dressed
Ruben Zakine, Yongfeng Zhao, Miloš Knežević +4
We analyze the surface tension exerted at the interface between an active fluid and a solid boundary in terms of tangential forces. Focusing on active systems known to possess an e…
Optomechanical conversion by mechanical turbines
Milos Knezevic, Mark Warner
Liquid crystal elastomers are rubbers with liquid crystal order. They contract along their nematic director when heated or illuminated. The shape changes are large and occur in a r…
Optomechanical elastomeric engine
Milos Knezevic, Mark Warner
Nematic elastomers contract along their director when heated or illuminated (in the case of photoelastomers). We present a conceptual design for an elastomer-based engine to extrac…
Photodynamics of stress in clamped nematic elastomers
Milos Knezevic, Mark Warner, Martin Copic +1
We describe the complex time-dependence of the build up of force exerted by a clamped photo-elastomer under illumination. Nonlinear (non-Beer) absorption leads to a bleaching wave…
Photoferroelectric solar to electrical conversion
Milos Knezevic, Mark Warner
We propose a charge pump which converts solar energy into DC electricity. It is based on cyclic changes in the spontaneous electric polarization of a photoferroelectric material, w…
Theory of photoferroelectric response in SmC* liquids
Milos Knezevic, Mark Warner
We are concerned with the modification of liquid crystalline and polar order in SmC* liquids by illumination. In particular we show that non-uniformity due to absorption and also d…
