Fine tuning and MOND in a metamaterial “multiverse”

Scientific Reports, 2017
We consider the recently suggested model of a multiverse based on a ferrofluid. When the ferrofluid is subjected to a modest external magnetic field, the nanoparticles inside the ferrofluid form small hyperbolic metamaterial domains, which from the ...

Control on Flow Separation over a Cylinder by a Ferrofluid Film Adsorbed by a Magnet

Inventions
Flow separation can lead to increased resistance and vibration generation, which is a difficult problem that cannot be ignored in engineering. In this paper, we propose a method of controlling flow separation by adsorbing ferrofluid onto the surface of a
