Simulation, characterisation and control of open quantum systems dynamics
… usually studied within the so-called Born-Markov approximation, the system-environment coupling is weak and such that we can perform a neat separation of timescales: the environmental dynamics is assumed to be fast compared to the typical evolution timescale of the system of interest. …

Using a symbolic language parser to Improve Markov language models
… language processing that combines an n-gram (Markov) model with a symbolic parser. In concert these two techniques are applied to the problem of sentence simplification. The n-gram system is comprised of a relational database backend with a frontend application that presents a homogeneous …

Open quantum systems and applications to the quantum information theory
… led to the following results. (i) Common approximations used in the study of analogous open quantum systems fail when the distance between the detectors becomes of the order of the relaxation time. In particular, the creation of correlations between remote detectors is not well described …

Quantum information and thermodynamics of general relativity
… matrix of the detector, invoking neither the Markov approximation nor the Rotating Wave Approximation (RWA). We find that at early times and in the regime of small accelerations, the non-Markovian effects are particularly pronounced, rendering the early-time transition rate non-thermal. The …

Optimal replacement in the proportional hazards model and its applications in a product-service system
… <p>In the first paper, a continuous time Markov covariate process is assumed to describe the condition of a system that is under periodic monitoring. Although the form of an optimal replacement policy for such a system in the PHM was developed previously, an approximation of the Markov …

Multiphoton correlations and emitters
… within the range of validity of the Born–Markov approximation and highlighting situations in which perturbation theory is applicable. Finally, we go beyond and take into account other statistical quantities such as the waiting time distribution or higher order correlators and eventually …

Joint throughput and delay optimization in multihop networks
As the use of the Internet evolves, more and more applications require quality of service constraints such as end-to-end delay requirements, in addition to throughput guarantees. We have developed a framework for rate and delay assignment in order to analyze networks of users with both rate and …
