FRIEDRICHS DYNAMICS APPLIED TO KAONS DECAY AND ENTANGLEMENT
We develop a hamiltonian dynamical approach to decoherence using a
Friedrichs model descrbing the interaction of a simple system of
finite degrees of freedoms with a large system with continuous
degrees of freedoms. The entanglment is due to the above
interaction. The model-system is also successfully applied to Kaons
decay and provides satisfying estimate of the experimental CP violation
parameter in the markovian approximation. The model provides also rich
description including decay, oscillations and regereneration. We also
report on some experiments demonstrating entanglement in mesonic
particles.The celebrated Kardar-Parisi-Zhang equation, initially
derived as a
model to describe the kinetic roughening of a growing interface, has
given rise to intense theoretical investigations for over two decades
since it stands as a simple -yet unsolved- model for scaling phenomena
and non-equilibrium phase transitions.
