Constraints from the CMB temperature and other common observational data-sets on variable dark energy density models
Cosmology Dark energy Thermodynamics
2011/10/13
The thermodynamic and dynamical properties of a variable dark energy model with density scaling as rho_x \propto (1+z)^m, z being the redshift, are discussed following the outline of Jetzer et al. Thi...
Spectrally narrow, long-term stable optical frequency reference based on a Eu$^{3+}$:Y$_{2}$SiO$_{5}$ crystal at cryogenic temperature
Spectrally narrow long-term stable optical frequency reference cryogenic temperature
2011/8/5
Abstract: Using an ultrastable continuous-wave laser at 580 nm we performed spectral hole burning of Eu$^{3+}$:Y$_{2}$SiO$_{5}$ at very high spectral resolution. Essential parameters determining the u...
Temperature (in)dependence of the Casimir-Polder potential of a particle near a metallic sphere
Casimir-Polder potential particle metallic sphere Temperature independence
2011/8/16
Abstract: It has recently been shown that the Casimir-Polder potential of a particle in an energy eigenstate near a conducting body can be virtually temperature independent, provided the separation be...
