Decoherence in Quantum Mechanics
Jurjen F. Koksma, Tomislav Prokopec, Michael G. Schmidt
We study decoherence in a simple quantum mechanical model using two approaches. Firstly, we follow the conventional approach to decoherence where one is interested in solving the r…
A Causal Alternative to Feynman's Propagator
Jurjen F. Koksma, W. Westra
The Feynman propagator used in the conventional in-out formalism in quantum field theory is not a causal propagator as wave packets are propagated virtually instantaneously outside…
Entropy and Correlators in Quantum Field Theory
Jurjen F. Koksma, Tomislav Prokopec, Michael G. Schmidt
It is well known that loss of information about a system, for some observer, leads to an increase in entropy as perceived by this observer. We use this to propose an alternative ap…
