Quantum semi-Markov processes.
We construct a large class of non-Markovian master equations that describe the dynamics of open quantum systems featuring strong memory effects, which relies on a quantum generalization of the concept of classical semi-Markov processes. General conditions for the complete positivity of the corresponding quantum dynamical maps are formulated. The resulting non-Markovian quantum processes allow t...
متن کاملRate Description of Markov Processes with Time Dependent Parameters∗
The description of physical, chemical or biological processes by simple models often becomes possible by a separation of time scales of the underlying microscopic dynamics [1,2]. For example, thermally activated transitions between locally stable states typically occur on a much slower time scale than the fast motion in the vicinity of these locally stable states [3]. On the long time scales on...
متن کاملTime Changed Markov Processes in Unified Credit - Equity Modeling ∗
This paper develops a novel class of hybrid credit-equity models with state-dependent jumps, local-stochastic volatility and default intensity based on time changes of Markov processes with killing. We model the defaultable stock price process as a time changed Markov diffusion process with state-dependent local volatility and killing rate (default intensity). When the time change is a Lévy sub...
متن کاملDiscrete Time Markov Processes
What follows is a quick survey of the main ingredients in the theory of discrete-time Markov processes. It is a birds' view, rather than the deenitive \state of the art." To maximize accessibility, the nomenclature of mathematical probability is avoided, although rigor is not sacriiced. To compensate, examples (and counterexamples) abound and the bibliography is annotated. Relevance to control ...
متن کاملModeling the Time-Dependent Rheological Properties of Pistachio Butter
Pistachio butter (semi solid paste), which is made from roasted pistachio kernels, is an appropriate alternative to work on because of its high nutritional and economical values. In this study, timedependent flow properties of pistachio butter were determined at two different temperatures (25˚C and 45˚C) for five different formulations (with different levels of emulsifying agents). Forward a...
