In this work we show that the supersymmetric economical SU(3)C ⊗ SU(3)L ⊗ U(1)X(33-1) gauge model has a realistic candidate for self-interacting dark matter. In the model under consideration, the right-handed sneutrino is in bottom of the triplet, which is a singlet of the Standard Model SU(2)L group. In addition, the right-handed sneutrino is the lightest slepton. By these properties, the righ...

We have shown experimentally that the thermal conductance through discrete, one-dimensional, ballistic phonon channels is quantized, G=πkB T/3h[1,2]. We have developed novel, 3D nanostructures, with feature sizes of order ~100nm to enter and reveal this mesoscopic limit for phonons. We will describe the techniques and implications of this measurement, and describe work in progress where we will...

Transparent conductors (TCs) have a variety of properties that can limit their performance in various applications. These properties include their optical and electronic behavior: optical transparency, electrical conductivity, plasma wavelength, ultraviolet absorption edge, work function, conductivity type; factors affecting device fabrication: synthesis temperature, thermal stability, resistan...

Developing new media for magnetic storage exhibiting perpendicular anisotropy, instead of the current longitudinal media, is a matter of the utmost importance [1]. The final goal is to produce a nanopatterned media able to overcome the superparamagnetic limit (information is lost due to thermal fluctuations) at room temperature. In this work, it is shown that nitrogen irradiation of thin films ...
