Nanoptennas are revolution in the field of digital and wireless communication technology. Plasmonics are capable of converting the concepts of microwave and radio frequency electronics to optical wavelengths by initiating faster, smaller and more efficient optical electronic interfaces. In other words, plasmonics build a bridge between photonics and electronics [1,2]. These plasmonics nanoptenn...

The Nambu–Jona-Lasinio and Sakai–Sugimoto models are juxtaposed, focusing on the models’ dynamically generated masses and the phase diagrams. The models are studied in the parameter space of temperature, constant electromagnetic fields and the quark chemical potential. When the chemical potential is zero or small, the models show good agreement. However, the responses of the models under the la...

We give detailed predictions for the spectral signatures arising from photon-particle oscillations in astrophysical objects. The calculations include quantum electrodynamic effects as well as those due to active relativistic plasma. We show that, by studying the spectra of compact sources, it may be possible to directly detect (pseudo)scalar particles, such as the axion, with much greater sensi...

Background With gold nanoparticles (AuNPs) is possible to develop nanoscale devices that can interact with chemical and biological systems. The phenomenon explored in these nanosystems is called Localized Surface Plasmon Resonance (LSPR), which promotes electromagnetic wave oscillation electronics on these small metallic structures. It is interesting to note that this resonance is directly link...

In this paper a comparative theoretical study was made of the magneto-optical response of square lattices of nanoobjects dots and rings . Expressions for both the polarizability of the individual objects as their mutual electromagnetic interactions for a lattice in vacuum was derived. The quantum-mechanical part of the derivation is based upon the commonly used envelope function approximation. ...

Electromagnetically induced transparency ~EIT!, a phenomenon well known in atomic systems, has a natural analogy in a classical magnetized plasma. The magnetized plasma has a resonance for right-hand polarized electromagnetic waves at the electron cyclotron frequency V0 , so that a probe wave with frequency v15V0 cannot propagate through the plasma. The plasma can be made transparent to such a ...

The strong evidence of neutrino oscillations from the solar, atmospheric and long baseline accelerator and reactor neutrino measurements implies finite neutrino masses and mixings[1,2]. Their physical origin and experimental consequences are not fully understood. Experimental studies on the neutrino properties and interactions can shed light to these fundamental questions and provide constraint...

Surface-enhanced Raman scattering (SERS) is recognized as one of the most sensitive spectroscopic tools offering highly sensitive chemical and biological detection. The fact that particle plasmon allows direct coupling of light to resonant electron plasmon oscillation has spurred tremendous efforts in the design and fabrication of highly SERS-active substrates in nanostructured films and metall...

Recently, it has been shown that cosmic neutrino flux at the GRB/AGN source, F 0 νe : F 0 νμ : F 0 ντ ≃ 1 : 2 : 0 , inevitably oscillates (in the three neutrino framework) to 1 : 1: 1, irrespective of the mixing angle relevant to the solar data. It has also been pointed out that the intrinsic flux of the cosmic highenergy neutrinos may not have the standard ratio, in which case the cosmic neutr...

Ground based tests were performed at the Max-Planck-Institute für Kernphysik Van de Graaff accelerator in Heidelberg, Germany to explore radiofrequency (RF) emission associated with hypervelocity particle impact induced plasma. Meteoroids and dust traveling between 11 and 72.8 km/s are constantly bombarding spacecraft while on orbit. These hypervelocity particles may cause electrical anomalies ...
