Relativistic Study of Motion of Photons in an Elliptical Gravitational Field [PDF]

Physics Access
Fields of elliptical objects can be considered elliptically symmetric, such that the structure, matter, and field of such an object can be defined in terms of an elliptically symmetric space metric.

Scrambling Power of Soft Photons [PDF]

, 2023
Observable scattering processes entail emission-absorption of soft photons. As these degrees of freedom go undetected, some information is lost. Whether some of this information can be recovered in the observation of the hard photons, depends of the ...

Demonstration of measurement-only blind quantum computing

New Journal of Physics, 2016
Blind quantum computing allows for secure cloud networks of quasi-classical clients and a fully fledged quantum server. Recently, a new protocol has been proposed, which requires a client to perform only measurements.

Mathematical Modeling of a Bioluminescent E. Coli Based Biosensor

Nonlinear Analysis, 2009
In this work we present a mathematical model for the bioreporter activity of an E. coli based bioluminescent bioreporter. This bioreporter is based on a genetically modified E. coli which harbors the recA promoter, a member of the bacterial SOS response,

Gravitoelectric effect in the condensed magnetic sea

IET Quantum Communication
Trapped graviton in magnetic seas induces magnetic fields as a function of time in the additional space. The Soon Joe generator made the Graviton set behave as free relativistic quantum particles. The current and voltage generated when the LED was turned
