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 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...
متن کاملMirage gauge coupling unification
We use compact D = 4, N = 1, Type IIB orientifolds as a testing ground for recent ideas about precocious gauge coupling unification and a low energy string scale. We find that certain such orientifolds have the interesting property that gauge couplings receive moduli-dependent corrections which mimic the effect of field theoretical logarithmic running. The effective cut-off scale for the logari...
