Calculation of a weak nonleptonic matrix element using “Weinberg” sum rules
Weak matrix element vector and axis vector spectrum function spectral function
2014/12/23
There is a ``toy'' weak matrix element which can be expressed as an integral over the vector and axial vector spectral functions, $\rho_V (s) - \rho_A (s)$. I review our recent evaluation of these spe...
Ab initio calculation of ideal strength and phonon instability of graphene in tension
strength phonon instability graphene
2012/8/8
Graphene-based sp2-carbon nanostructures such as carbon nanotubes and nanofibers can fail
near their ideal strengths due to their exceedingly small dimensions. We have calculated the
phonon spectra ...

Spectral Airglow Temperature imager sector temperature sector spectre median filter
2011/8/3
Abstract: The Spectral Airglow Temperature Imager is an instrument, specially designed for investigation of the wave processes in the Mesosphere-Lower Thermosphere. In order to determine the kinematic...
Quasi-bound states in the continuum: a dynamical coupled-channel calculation of axial-vector charmed mesons
Quasi-bound coupled-channel axial-vector
2011/9/14
Masses and widths of the charmed axial-vector mesons D1(2420), D1(2430), Ds1(2536), and Ds1(2460) are calculated nonperturbatively in the Resonance-Spectrum-Expansion model, by coupling various open a...

Calculation and Application of New Quantum Bounds
Calculation New Quantum Bounds determines arbitrary Quantum Bounds algorithm
2011/7/27
Abstract: We review, correct, and develop an algorithm which determines arbitrary Quantum Bounds, based on the seminal work of Tsirelson [Lett. Math. Phys. 4, 93 (1980)]. The vast potential of this al...

2011/7/27
Abstract: Mathematical models and computer algorithms are developed to calculate dynamic stress concentration and fracture wave propagation in a reinforced composite sheet. The composite consists of a...
Quantum Mechanical Simulation of Electronic Transport in Nanostructured Devices by Efficient Self-consistent Pseudopotential Calculation
Quantum Mechanical Simulation of Electronic Transport Nanostructured Devices
2010/11/17
We present a new empirical pseudopotential (EPM) calculation approach to simulate the million
atom nanostructured semiconductor devices under potential bias using the periodic boundary con-
ditions....
First Principle Calculation of Potential and Multi-Channel Transport in Fe/MgO/Fe Hetero-Junction
Hetero-Junctions Electronic Transport S-Matrix Theory
2010/7/5
In this work we studied the behavior of multi-channel tunneling through a realistic Fe/MgO/Fe hetero-junction ab initio potential. For this purpose we obtained Fe/MgO/Fe(001) hetero-junction effective...
