Little Big Photon
نویسنده
چکیده
18 P hotons come in many beautiful colors and are very useful for transmitting information with little loss over large distances. However, photons are also a little boring: they essentially do not interact with one another. This absence of interactions, or equivalently, the linearity of the optical response, is what allows one to send powerful optical pulses over large distances through optical fibers without much signal distortion. It is also what makes photons good carriers of quantum states, that can be encoded in the photons’ polarization, frequency, or time of arrival.

An investigation of using hump in the Cherenkov photon lateral distribution for Gamma-Hadron separation
Simulation of gamma and hadron showers in the energy range 100GeV- 25TeV has been carried out. For a big ideal Cherenkov light array, characteristics of lateral distribution of Cherenkov photon density have been studied. Results from this ideal detector are compared with those simulated for a real TUNKA- like array to investigate experimental potential of using existence of a hump in lateral di...
متن کاملExploring Culture-Related Content in English Textbooks: A Closer Look at Advanced Series of Iran Language Institute
The aim of this article was to examine three advanced textbooks in Iran Language Institute (ILI) in an attempt to establish if they differ in the extent to which they represent dimension of big ‘C’ culture and little ‘c’ culture, their stance in distribution of references of cultural category, and also what themes predominate. The analysis identifies just the cultural elements, and culture–free...
متن کاملSecond dual space of little $alpha$-Lipschitz vector-valued operator algebras
Let $(X,d)$ be an infinite compact metric space, let $(B,parallel . parallel)$ be a unital Banach space, and take $alpha in (0,1).$ In this work, at first we define the big and little $alpha$-Lipschitz vector-valued (B-valued) operator algebras, and consider the little $alpha$-lipschitz $B$-valued operator algebra, $lip_{alpha}(X,B)$. Then we characterize its second dual space.
متن کاملCultural Components and Subcomponents in Two Persian and English Language Teaching Textbooks: A Comparative Study
The present qualitative research, for the first time, aimed at comparing and contrasting the extent cultural components and subcomponents are represented in the elementary levels of A Course in General Persian and Top Notch Series as foreign language teaching textbooks. The adapted checklist of Lee's Big ‘C' and little ‘c' cultural components (2009) was used for the current study. After conten...
متن کاملPrimordial Deuterium Abundance and Cosmic Baryon Density
The comparison of cosmic abundances of the light elements with the density of baryonic stars and gas in the universe today provides a critical test of big bang theory and a powerful probe of the nature of dark matter. A new technique allows determination of cosmic deuterium abundances in quasar absorption clouds at large redshift, allowing a new test of big bang homogeneity in diverse, very dis...
