Various electromagnetic systems can carry an angular momentum in their E and B fields. The electromagnetic field angular momentum (EMAM) of these systems can combine with the spin angular momentum to give composite fermions or composite bosons. In this paper we examine the possiblity that an EMAM could provide an explanation of the fractional quantum Hall effect (FQHE) which is complimentary to...

We examine the vortex states in a 2D superconductor interacting with a square array of pinning sites. As a function of increasing pinning size or strength we find a series of novel phases including multivortex and composite superlattice states such as aligned dimer and trimer configurations at individual pinning sites. Interactions of the vortices give rise to an orientational ordering of the i...

I review the dynamical symmetry breaking (DSB) approach to the Origin of Mass, which is traced back to the original (2008 Nobel prize) work of Nambu based on the BCS analogue of superconductor where mass of nucleon (then elementary particle) arises due to Cooper paring and pions are provided as massless Nambu-Goldstone (NG) bosons, being composite as in Fermi-Yang/Sakata model. In this talk I w...

A double percolation transition is identified in a binary network composed of nanoparticles of MgB2 superconductor and CrO2 half-metallic ferromagnet. Anomalously high-resistance or insulating state, as compared to the conducting or superconducting states in single-component systems of either constituent, is observed between two distinct percolation thresholds. This double percolation effect, w...

We report experimental evidence of the formation antiferromagnetic clusters well within cuprate superconductor ${\mathrm{La}}_{1.85}{\mathrm{Sr}}_{0.15}{\mathrm{CuO}}_{4}$ (LCu) in a composite made LCu and ferromagnet ${\mathrm{La}}_{0.6}{\mathrm{Sr}}_{0.4}{\mathrm{CoO}}_{3}$ (LCo). It is found that exchange field LCo suppresses dynamic spin fluctuation short-range-ordered superparamagnetic typ...
