Two-photon imaging and quantum holography
Gunnar Bjork, Jonas Soderholm, Luis L. Sanchez-Soto
It has been claimed that ``the use of entangled photons in an imaging system can exhibit effects that cannot be mimicked by any other two-photon source, whatever strength of the co…
Star Formation Rate estimators: [OII]3727 vs. Halpha for local star-forming galaxies
A. Aragon-Salamanca, A. Alonso-Herrero, J. Gallego +4
The [OII]3727 emission line is frequently used as an indicator of the star formation rate (SFR) despite its complex dependence on metallicity and excitation conditions. We have ana…
Effective Hamiltonians in quantum optics: a systematic approach
A. B. Klimov, L. L. Sanchez-Soto, A. Navarro +1
We discuss a general and systematic method for obtaining effective Hamiltonians that describe different nonlinear optical processes. The method exploits the existence of a nonlinea…
12CO mapping of the low-metallicity BCD galaxy Mrk86
A. Gil de Paz, S. A. Silich, B. F. Madore +3
We have mapped the 12CO J=1-0 and J=2-1 line emission in Mrk86, one of the most metal-deficient Blue Compact Dwarf galaxies so far detected in 12CO. The 12CO emission is distribute…
Natural majorization of the Quantum Fourier Transformation in phase-estimation algorithms
Roman Orus, Jose I. Latorre, Miguel A. Martin-Delgado
We prove that majorization relations hold step by step in the Quantum Fourier Transformation (QFT) for phase-estimation algorithms considered in the canonical decomposition. Our re…
An exponential function on the set of varieties
S. M. Gusein-Zade, I. Luengo, A. Melle-Hernandez
Let be either the Grothendieck semiring (semiring with multiplication) of complex algebraic varieties, or the Grothendieck ring of these varieties, or the Grothendieck rin…
