Damped harmonic oscillators in the holomorphic representation
F. Benatti, R. Floreanini
Quantum dynamical semigroups are applied to the study of the time evolution of harmonic oscillators, both bosonic and fermionic. Explicit expressions for the density matrices descr…
Non-Standard neutral kaons dynamics from D-brane statistics
F. Benatti, R. Floreanini
The neutral kaon system can be effectively described by non-unitary, dissipative, completely positive dynamics that extend the usual treatment. In the framework of open quantum sys…
On the decay law for unstable open systems
F. Benatti, R. Floreanini
We use (nonconservative) dynamical semigroups to investigate the decay law of a quantum unstable system weakly coupled with a large environment. We find that the deviations from th…
Complete Positivity and the K K-bar system
F. Benatti, R. Floreanini
Models that provide experimentally testable violations of ordinary Quantum Mechanics have been recently proposed. These models are based on non-unitary time evolutions of density m…
Quantum Mechanical Breaking of Local GL(4) Invariance
R. Floreanini, R. Percacci
We consider the gravitational coupling of a scalar field, in a reformulation of General Relativity exhibiting local GL(4) invariance at the classical level. We compute the one-loop…
Positive energy representations of the conformal quantum algebra
L. Dabrowski, V. K. Dobrev, R. Floreanini +1
The positive-energy unitary irreducible representations of the -deformed conformal algebra are obtained by appropriate deformation of the clas…
