Considered an ultra-hot Jupiter – a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain – the fiery, inferno-like WASP-76b exoplanet may be even more siz...
A signal-strength model for gravity-field spectrum components in a local space
Earth's Gravitational Potential Local Area Spectrum Structure Spherical Cap Harmonic Analysi
2015/8/26
In the Earth gravity-field model, potential coefficients are projections of the Earth gravitational potential on the corresponding spherical harmonics by degree and order. These coefficients reflect t...
Low frequency signal spectrum analysis for strong earthquakes
VLF/LF signal propagation eartquake precursors
2015/8/24
We examined changes in the spectral composition of the low frequency (LF) subionospheric signals from the NRK transmitter (37.5 kHz) in Iceland that were received in Bari (Italy) relative to the earth...
THE CASE FOR UNLICENSED SPECTRUM

The introduction in the past few years of mobile devices such as the iPhone, iPad
and Android phones has led to vast increases in the use of wireless data communications,
and most forecasters anti...

A morphological orientation spectra is proposed. This spectrum describes basic directions of shape parts. Fast discrete-continuous
algorithm for computing orientation spectrum is presented. It is bas...
Spontaneous emission spectrum of a V-type three-level atom in a Fabry–Perot cavity containing left-handed materials
Spontaneous emission spectrum V-type three-level atom Fabry–Perot cavity left-handed materials
2014/5/28
The spontaneous emission of a V-type Zeeman atom in a Fabry–Perot cavity containing left-handed materials(LHMs) is investigated. Because of the strong indirect quantum interference induced by the refo...
The excited hadron spectrum in lattice QCD using a new variance reduction method
The excited hadron spectrum lattice QCD

Progress in calculating the spectrum of excited baryons and mesons in lattice QCD is described. Correlation matrices of sets of spatially-extended hadron operators have been studied and their effectiv...
Poisson Statistics in the High Temperature QCD Dirac Spectrum
Poisson Statistics the High Temperature QCD Dirac Spectrum
2010/12/27
At low temperature in the epsilon regime of QCD the low-end of the Dirac spectrum is described by random matrix theory. In contrast, there has been no similarly well established staistical descriptio...
A test of the bosonic spinon hypothesis for the triangular antiferromagnet spectrum
bosonic spinon hypothesis triangular antiferromagnet spectrum
2010/11/18
We compute the dynamical structure factor of the spin-1/2 triangular Heisenberg model using a
Schwinger boson mean field theory. We find that the reconstructed dispersion, resulting from a non trivia...
Back reaction, emission spectrum and entropy spectroscopy

Controlling single diamond NV color center photoluminescence spectrum Fabry-Perot microcavity
2010/11/9
We present both theoretical and experimental results on fluorescence of single defect centers in diamond nanocrystals embedded in a planar dielectric microcavity. From a theoretical point of view, we ...

Entanglement spectrum random-singlet quantum critical points
2010/10/22
The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
