Coherent Electrodynamic Processes in Solid Molecular Hydrogen

The many experimental puzzles of solid hydrogen, that seem to defy the generally accepted view of condensed matter, are shown to be a rather straightforward consequence of a new approach to condensed matter physics, that takes into account the coherent electrodynamic processes, predicted by Quantum ElectroDynamics (QED), that have been so far overlooked. As a consequence, a revision of the pres...

Molecular Crystals and Liquid Crystals

The problem of finding the equilibrium shape of a small particle by the Wulff construction is reviewed briefly, with emphasis on its applications to liquid crystals. The proof of Wulff’s theorem is stated in a concise mathematical form. Some typical equilibrium shapes of liquid crystalline cirops are described. When there is orientational order of the molecules in the liquid crystal but no tran...

Molecular Crystals and Liquid Crystals

A series of new heterocyclic stable free radicals based on the thioaminyl fragment 1 was designed in order to introduce a x-delocalized spin to the rigid cores of mesogenic molecules. The design allows for preparation of calamitic and discotic liquid crystals. Computational analysis and first experimental results of the radicals (ESR) are presented. The thioaminyl group' (1) has been featured a...
