A calculation scheme for spectral densities of strongly correlated electron systems using exact diagonalization of dynamical mean field theory
Song-Jin O, Hak-Chol Pak, Kwang-Il Ryom +1
A new approach for calculating spectral density functions of strongly correlated electron systems is proposed within the exact diagonalization method of dynamical mean-field theory…
Path Integral by Space-time Slicing Approximation In Open Bosonic String Field
Am-Gil Ri, Tae-Song Kim, Chol-Man Ri +1
In our paper, we considered how to apply the traditional Feynman path integral to string field. By constructing the complete set in Fock space of non-relativistic and relativistic…
Classical Equation of Electromagnetic Field in the Higgs Boson Field and Estimation on the Static Electrical Polarizability of Leptons
Il-Gwang Kim, Tae-Song Kim, Chol-Man Ri +1
In our paper we derived the classical motion equation of electromagnetic field in space with Higgs field and by means of it discussed the distributions of charge and current formed…
Mechanism of the Fano resonance in a planar metamaterials: Analysis from the coupled two-oscillator model
Song-Kum Song, Song-Jin Im
Mechanism of the Fano resonances in planar metamaterials demonstrate based on the coupled two-oscillator model. We have described the optical spectrums like reflectance and transmi…
Experimental study on the influence of binders on plastic deformation during sintering of cubic boron nitride powder under high pressure and high temperature
Su-Gon Kim, Gwang-Il Jon, Song-Jin Im
In this work, sintered polycrystalline cubic boron nitride (cBN) compacts, with titanium carbonitride (TiC0.7N0.3) and titanium nitride (TiN), respectively, as binders, were prepar…
Suppression of DC term in Fresnel digital holography by sequence subtraction of holograms
Jong-Chol Kang, Chol-Su Kim, Song-Jin Im
An experimental method for suppression of DC term in the reconstructed images from Fresnel digital holograms is presented. In this method, two holograms for the same object are cap…
