Nematic ordering of semi-flexible polymers confined on a toroi...

We study the isotropic-like and nematic states of wormlike liquid-crystal polymers embedded on the surface of a torus. The role played by surface curvature, which couples with the molecular rigidity, is reported as the main reason that causes the ... RSC, 1 week ago

[Report] Ubiquitous signatures of nematic quantum criticality in optimally doped Fe-based superconductors

A key actor in the conventional theory of superconductivity is the induced interaction between electrons mediated by the exchange of virtual collective fluctuations (phonons in the case of conventional s-wave superconductors). Other collective modes ...

Density functional theory of nematic elasticity: softening from the polar order

Recent experiments have evidenced some unconventional features in the elasticity of nematics, which cannot be explained by standard microscopic theories. Here, in the framework of a second-virial density functional theory, we have developed a ...

Nematic ionic liquid crystals based on pyridinium salts derived from 4-hydroxypyridine

A series of pyridinium salts with various counterions (Br-, NO3-, BF4-, PF6-, OTf- and SCN-) and different spacer chain lengths, which display a nematic phase has been designed and prepared. They are derived from 4-hydroxypyridine and possess two ...

Simulating the pitch sensitivity of twisted nematics of patchy rods

Stiff, elongated biomolecules such as filamentous viruses, DNA or cellulose nanocrystals are known to form liquid crystals often exhibiting a helical supramolecular organization. Little is known about the microscopic origin, size and handedness of ...
