Teaching Holography: Holography as a Teaching Tool
The holo-diagram is a diagram originally designed as a tool for teaching the making and evaluation of holograms. It was soon found to include much more general uses than first expected. During the 20 years since its introduction we have applied this diagram to explain many different fields such as holography, interferometry, diffraction. Fermat's principle, light-in-flight recordings, threedime...
متن کاملInstantons and Conformal Holography
We study a subsector of the AdS4/CFT3 correspondence where a class of solutions in the bulk and on the boundary can be explicitly compared. The bulk gravitational theory contains a conformally coupled scalar field with a φ potential, and is holographically related to a massless scalar with a φ interaction in three dimensions. We consider the scalar sector of the bulk theory and match bulk and b...
متن کاملMigdal’s model and Holography
More than 30 years ago Migdal proposed a model for hadronic resonances based on rational approximants [1]. The final aim was to determine the spectrum of vector mesons in the large-Nc limit which best fulfills quarkhadron duality. The strategy was to start from the short distance behavior of the vector vacuum polarization function < V V > and build the Padé approximant thereof. Migdal further s...
متن کاملTwistors, Cft and Holography
According to one of many equivalent definitions of twistors a (null) twistor is a null geodesic in Minkowski spacetime. Null geodesics can intersect at points (events). The idea of Penrose was to think of a spacetime point as a derived concept: points are obtained by considering the incidence of twistors. One needs two twistors to obtain a point. Twistor is thus a “square root” of a point. In t...
متن کاملHolography and Cosmology
A cosmological version of the holographic principle is proposed. Various consequences are discussed including bounds on equation of state and the requirement that the universe be infinite.
