125 GeV Higgs as a pseudo-Goldstone boson in supersymmetry with vector-like matters

We propose a possibility of the 125 GeV Higgs being a pseudo-Goldstone boson in supersymmetry with extra vector-like fermions. Higgs mass is obtained from loops of top quark and vector-like fermions from the global symmetry breaking scale f at around TeV. The mu, Bmu/mu \sim f are generated from the dynamics of global symmetry breaking and the Higgs quartic coupling vanishes at f as tan beta \simeq 1. The relation of msoft \sim $4\pi M_Z$ with f \sim mu \sim m_soft \sim TeV is obtained and large mu does not cause a fine tuning for the electroweak symmetry breaking. The Higgs to di-photon rate can be enhanced from the loop of uncolored vector-like matters. The stability problem of Higgs potential with vector-like fermions can be nicely cured by the UV completion with the Goldstone picture.Comment: 28 pages, 8 figure

NRG for the bosonic single-impurity Anderson model: Dynamics

The bosonic single-impurity Anderson model (B-SIAM) is studied to understand the local dynamics of an atomic quantum dot (AQD) coupled to a Bose-Einstein condensation (BEC) state, which can be implemented to probe the entanglement and the decoherence of a macroscopic condensate. Our recent approach of the numerical renormalization group (NRG) calculation for the B-SIAM revealed a zero-temperature phase diagram, where a Mott phase with local depletion of normal particles is separated from a BEC phase with enhanced density of the condensate. As an extension of the previous work, we present the calculations of the local dynamical quantities of the B-SIAM which reinforce our understanding of the physics in the Mott and the BEC phases.Comment: 12 pages, 13 figure

Flexible and transparent supercapacitors and fabrication using thin film carbon electrodes with controlled morphologies

Mechanically flexible and optically transparent thin film solid state supercapacitors are fabricated by assembling nano-engineered carbon electrodes in porous templates. The electrodes have textured graphitic surface films with a morphology of interconnected arrays of complex shapes and porosity. The graphitic films act as both electrode and current collector, and when integrated with solid polymer electrolyte function as thin film supercapacitors. The nanostructured electrode morphology and conformal electrolyte packaging provide enough energy and power density for electronic devices in addition to possessing excellent mechanical flexibility and optical transparency

Transparent, flexible supercapacitors from nano-engineered carbon films

Here we construct mechanically flexible and optically transparent thin film solid state supercapacitors by assembling nano-engineered carbon electrodes, prepared in porous templates, with morphology of interconnected arrays of complex shapes and porosity. The highly textured graphitic films act as electrode and current collector and integrated with solid polymer electrolyte, function as thin film supercapacitors. The nanostructured electrode morphology and the conformal electrolyte packaging provide enough energy and power density for the devices in addition to excellent mechanical flexibility and optical transparency, making it a unique design in various power delivery applications

Spectral Density Scaling of Fluctuating Interfaces

Covariance matrix of heights measured relative to the average height of a growing self-affine surface in the steady state are investigated in the framework of random matrix theory. We show that the spectral density of the covariance matrix scales as $\rho(\lambda) \sim \lambda^{-\nu}$ deviating from the prediction of random matrix theory and has a scaling form, $\rho(\lambda, L) = \lambda^{-\nu} f(\lambda / L^{\phi})$ for the lateral system size $L$, where the scaling function $f(x)$ approaches a constant for $x \ll 1$ and zero for $x \gg 1$. The obtained values of exponents by numerical simulations are $\nu \approx 1.73$ and $\phi \approx 1.40$ for the Edward-Wilkinson class and $\nu \approx 1.64$ and $\phi \approx 1.79$ for the Kardar-Parisi-Zhang class, respectively. The distribution of the largest eigenvalues follows a scaling form as $\rho(\lambda_{max}, L) = 1/L^b f_{max} ((\lambda_{max} -L^a)/L^b)$, which is different from the Tracy-Widom distribution of random matrix theory while the exponents $a$ and $b$ are given by the same values for the two different classes

Bioproduction of Molecules for Structural 3D Printing Filaments

In our laboratory, we are focused on the study of plant cells and their use in daily, real-world applications. Our main goal is to produce organic, conductive, and biodegradable material to be used by KAMPERS collaborators. Physcomitrella patens is the model organism we have used. We have created a ggb knockout mutant line of P. patens which is long lasting (immortal) and advantageous over wild-type strains for use in bioreactors. Our laboratory has identified several different metabolic pathways that have potential uses in creating conductive material for use in 3D printing. These pathways are the polyisoprene pathway, the polyacetylene pathway, and the polythiophene pathway. These pathways will be manipulated in P. patens to maximize the production of the monomers needed for polymerization of these materials. Our model systems will be optimized to efficiently create these materials and increase their biomass. We have also found that Eumelanin is a promising conductive material.https://ir.library.louisville.edu/uars/1027/thumbnail.jp
