Resolution of Biological Microstructure Through In Situ Fluorescence Emission Spectra: An Oceanographic Application Using Optical Fibers
Situ Fluorescence Emission Spectra Biological Microstructure
2015/8/19
One of the challenges we face as oceanographers is the wide range of spatial and temporal scales over which we must measure the physical, biological, and chemical properties and processes in the ocean...
Dipole-Quadrupole Theory of Surface Enhanced Infrared Absorption and Appearance of Forbidden Lines in the SEIRA Spectra of Symmetrical Molecules
Dipole-Quadrupole Theory Surface Enhanced Infrared Absorption and Appearance Forbidden Lines the SEIRA Spectra Symmetrical Molecules Optics
2012/4/20
The paper presents main aspects of the Dipole-Quadrupole theory of Surface Enhanced Infrared Absorption (SEIRA). It is pointed out the possibility of appearance of the lines, caused by totally symmetr...
Meson spectra from overlap fermion on domain wall gauge configurations
pectra overlap fermion
2011/1/7
We report meson spectra obtained by using valence overlap fermion propagators generated on a background of 2+1 flavor domain wall fermion gauge configurations on 16^3 X 32, 24^3 X 64 and 32^3 X 64 lat...
Failure of t-J models in describing doping evolution of spectral weight in x-ray scattering, optical and photoemission spectra of the cuprates
t-J models x-ray scattering optical and photoemission spectra cuprates
2010/11/19
We have analyzed experimental evidence for an anomalous transfer of spectral weight from high
to low energy scales in both electron and hole doped cuprates as a function of doping. X-ray
scattering,...
The importance of inter-site coherences in the x-ray absorption spectra of mixed-valent systems
inter-site coherences in the x-ray mixed-valent systems
2010/11/19
We study the importance of inter-site coherences and quantum interference effects in
the x-ray absorption spectroscopy (XAS) of mixed-valent systems. We demonstrate its importance,
first for a simpl...
Influence of Phase Matching on the Cooper Minimum in Ar High Harmonic Spectra
the Cooper Minimum Harmonic Spectra
2010/11/16
We study the influence of phase matching on interference minima in high harmonic spectra. We concentrate on structures in atoms due to interference of different angular momentum channels during recom...
Emission spectra and intrinsic optical bistability in a two-level medium
Emission spectra intrinsic optical bistability two-level medium
2010/11/5
Scattering of resonant radiation in a dense two-level medium is studied theoretically with account for local field effects and renormalization of the resonance frequency. Intrinsic optical bistability...
We propose a methodology to construct excited states with a fixed angular momentum, namely,
“yrast excited states” of finite-size one-dimensional bosonic systems with periodic boundary conditions.The...
