Space-Time Codes for Wireless Optical Communications
A space-time channel coding technique is presented for overcoming turbulence-induced fading in an atmospheric optical heterodyne communication system that uses multiple transmit and receive apertures. In particular, a design criterion for minimizing the

Statistical predictions for the dynamics of a low-speed system: Newtonian versus special-relativistic mechanics. [PDF]
The newtonian and special-relativistic statistical predictions for the mean, standard deviation and probability density function of the position and momentum are compared for the periodically-delta-kicked particle at low speed.

Relaxation of Higgs mass and cosmological constant with four-form fluxes and reheating
We consider the most general effective action for the four-form fluxes in the Standard Model coupled to gravity. The Higgs mass parameter can be relaxed to a correct value due to the four-form coupling to the Higgs field and it stops changing due to an ...

Quantum field-theoretical descriprion of neutrino oscillations in T2K experiment [PDF]
We consider neutrino oscillations in the T2K experiment using a new quantum field-theoretical approach to the description of processes passing at finite space-time intervals.

Doubly Quantum Mechanics [PDF]
Motivated by the expectation that relativistic symmetries might acquire quantum features in Quantum Gravity, we take the first steps towards a theory of ''Doubly'' Quantum Mechanics, a modification of Quantum Mechanics in which the geometrical ...
