Some Jump Processes in Quantum Field Theory
نویسنده
چکیده
A jump process on configuration space whose transition rates are governed by the state vector of a quantum field theory was first considered by J.S. Bell. This process and its variants involving “minimal” jump rates are reviewed, and a recent proof of global existence of Bell’s process is sketched. As an outlook, it is suggested how methods of this proof could be applied to similar global existence questions, and the particular usefulness of minimal jump rates on manifolds with boundaries is underlined.

Some Jump Processes in Quantum Field Theory
A jump process for the positions of interacting quantum particles on a lattice, with time-dependent transition rates governed by the state vector, was first considered by J.S. Bell. We review this process and its continuum variants involving “minimal” jump rates, describing particles as they get created, move, and get annihilated. In particular, we sketch a recent proof of global existence of B...

The jump process introduced by J. S. Bell in 1986, for defining a quantum field theory without observers, presupposes that space is discrete whereas time is continuous. In this letter, analogous processes in discrete time are introduced. MSC (2000): 81T25, 60J10. PACS: 02.50.Ga; 03.65.Ta.
متن کاملThe Quantum Statistical Mechanical Theory of Transport Processes
A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
متن کاملApplication of Stochastic Optimal Control, Game Theory and Information Fusion for Cyber Defense Modelling
The present paper addresses an effective cyber defense model by applying information fusion based game theoretical approaches. In the present paper, we are trying to improve previous models by applying stochastic optimal control and robust optimization techniques. Jump processes are applied to model different and complex situations in cyber games. Applying jump processes we propose some m...

The jump process introduced by J. S. Bell in 1986, for defining a quantum field theory without observers, presupposes that space is discrete whereas time is continuous. In this letter, our interest is to find an analogous process in discrete time. We argue that a genuine analog does not exist, but provide examples of processes in discrete time that could be used as a replacement. MSC (2000): 81...
