Energy-Momentum Conservation and Holographic S-Matrix
نویسنده
چکیده
We investigate the consequence of the energy-momentum conservation law for the holographic S-matrix from AdS/CFT correspondence. It is shown that the conservation law is not a natural consequence of conformal invariance in the large N limit. We predict a new singularity for the four point correlation function of a marginal operator. Only the two point scattering amplitude is explicitly calculated, and the result agrees with what is expected.

Conservation of Energy Implies Conservation of Momentum: How We Can Explain Conservation of Momentum to Before-Calculus Students
In solving physics problems, it is often important to use the laws of conservation of energy and momentum. While most people have intuitive understanding of energy and of its conservation, there is usually no intuition behind momentum, and known textbook derivations of conservation of momentum use calculus – which is usually taught after momentum. In this paper, we show how the law of conservat...
متن کاملBrane Cosmology Solutions with Bulk Scalar Fields
Brane cosmologies with static, five-dimensional and Z2 symmetric bulks are analysed. A general solution generating mechanism is outlined. The qualatitive cosmological behaviour of all such solutions is determined. Conditions for avoiding naked bulk singularities are also discussed. The restrictions placed on the solutions by the assumption of such a static bulk are investigated. In particular t...
متن کاملThe light-front gauge-invariant energy-momentum tensor
We provide for the first time a complete parametrization for the matrix elements of the generic asymmetric, non-local and gauge-invariant canonical energymomentum tensor, generalizing therefore former works on the symmetric, local and gaugeinvariant kinetic energy-momentum tensor also known as the Belinfante-Rosenfeld energymomentum tensor. We discuss in detail the various constraints imposed b...
متن کاملEnergy-momentum Tensors in Matrix Theory and in Noncommutative Gauge Theories
Noncommutative gauge theories can be realized by considering branes in string theory with a strong NS-NS two-form field [1]–[11]. In our previous paper [12], we derived the energy-momentum tensors of these theories by computing disk amplitudes with one closed string and an arbitrary number of open strings and by taking the Seiberg-Witten limit [10] of these amplitudes. We found that the energym...
متن کاملMeasuring the deposited energy from a non-ionizing laser beam in water by digital holographic interferometry
Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
