Collinear mirage effect at a microscopic scale
This demonstration of mirage effect under a microscope provides a new possibility to measure the thermal diffusivity of a transparent sample as small as a few microns, with micronic spatial resolution. Mirage effect [ l] is now a classical technique of photothermal physics. The modulated heating beam is focused at normal incidence on the sample's surface, while the probe beam runs either along ...
متن کاملMirage Cosmology
A brane universe moving in a curved higher dimensional bulk space is considered. The motion induces a cosmological evolution on the universe brane that is indistinguishable from a similar one induced by matter density on the brane. The phenomenological implications of such an idea are discussed. Various mirage energy densities are found, corresponding to dilute matter driving the cosmological e...
متن کاملA photothermal ”mirage” imaging system
We describe a scanning mirage microscope system that uses a diode probe laser. The sample is raster scanned using X-Y motorised microstepping stages under an Ar+ pump beam to give two dimensional scans and depth profiles. The results for a test sample are given and are compared to that obtained by scanning using a conventional large photoacoustic (PA) cell.
متن کاملProspects for Mirage Mediation
Mirage mediation reduces the fine-tuning in the minimal supersymmetric standard model by dynamically arranging a cancellation between anomaly-mediated and modulus-mediated supersymmetry breaking. We explore the conditions under which a mirage “messenger scale” is generated near the weak scale and the little hierarchy problem is solved. We do this by explicitly including the dynamics of the SUSY...
