Nematic and almost-tetratic phases of colloidal rectangles
Physical Review E, 2007Nonspherical colloids can exhibit liquid-crystalline phases with different degrees of broken orientational and translational symmetry. Here we investigate hard rectangles consisting of photolithographically prepared disks standing on edge. We observe a conventional Kosterlitz-Thouless transition from isotropic to nematic with almost smectic behavior at

Quantum communications: Tetrat coding
Physical Review A, 1998This work shows that an orthogonal tetrat basis element made up of two photons can be generated with two optical parametric down-converters and identified with a multiport detection system for coincidences. The transmission gain over the usual coding in bits is $g=2.$ The information is assigned to each photon pair using a single conjugate beam of the ...

Crystal Bridges, Tetratic Order, and Elusive Equilibria: The Role of Structure in Lubrication Films
The Journal of Physical Chemistry B, 2007In this paper, we report on molecular dynamics simulation studies of thin dodecane films confined between mica surfaces. On confinement, the film undergoes a surface-mediated transition into a novel phase characterized by tetratic orientational order.

Tetratic phase of Hertzian spheres: Monte Carlo simulation
The Journal of Chemical Physics, 2013The nature of the melting transition of a bilayer comprising Hertzian spheres, confined between parallel walls, was investigated with the multicolour domain decomposition Monte Carlo simulation. It was confirmed that an ordered bilayer structure with a square lattice symmetry appeared parallel to the walls of confinement at a certain density and ...

Topological defects of tetratic liquid-crystal order on a soft spherical surface
Soft Matter, 2013We model the orientational and positional order of tetratically shaped molecules, each having four-fold structural symmetry, confined on a spherical surface. Our Monte Carlo simulation shows that at a high molecular density, a tetratic orientational order develops in the system, accompanied by eight disclinations arranged in an anticube configuration ...
