Book Description
Discrete-event simulations are often non-Markovian in the sense that the underlying stochastic process of the simulation cannot be modeled as a Markov chain with countable state space. We discuss regenerative simulation methods for non-Markovian systems whose underlying stochastic process can be represented as a generalized semi-Markov process. Applications to modeling and simulation of ring and bus networks are given. Keywords include: Regenerative simulation; Generalized semi-Markov processes; Non-Markovian systems; Recurrence and regeneration; Ring and bus networks.

Book Description
A generalized semi-Markov process provides a stochastic process model for a discrete-event simulation. This representation is particularly useful for non-Markovian systems where it is nontrivial to obtain recurrence properties of the underlying stochastic processes. The authors develop geometric trials arguments which can be used to obtain results on recurrence and regeneration in this setting. Such properties are needed to establish estimation procedures based on regenerative processes. Applications to modeling and simulation of ring and bus networks are discussed. (Author).

Book Description
We present an algorithm to transform a subset of generalized semi-Markov processes into semi-Markov processes. The transformation preserves steady-state simulation, a simulation that allows us to retrieve the steady state probability of the generalized semi-Markov process from that of the transformed process. The method presented could generate semi-Markov processes with big state spaces, for that reason we introduce two state simplification techniques. The first one deals with the state space explosion problem by deleting states from the original generalized semi-Markov process. The technique deletes states from the generalized semi-Markov process while preserving the distribution of time needed to travel between non-deleted states; as well as the transient state probabilities of a subset of the states in the process. The second technique deals with the state space explosion problem at the level of semi-Markov processes. It works by deleting states from the semi-Markov processes while preserving the average time to travel between non-deleted states, as well as the steady state probabilities of a subset of the states in the process.

Book Description
We present a quantum algorithm to simulate general finite dimensional Lindblad master equations without the requirement of engineering the system-environment interactions. The proposed method is able to simulate both Markovian and non-Markovian quantum dynamics. It consists in the quantum computation of the dissipative corrections to the unitary evolution of the system of interest, via the reconstruction of the response functions associated with the Lindblad operators. Our approach is equally applicable to dynamics generated by effectively non-Hermitian Hamiltonians. We confirm the quality of our method providing specific error bounds that quantify its accuracy.

Book Description
This book is a collection of multidisciplinary papers presented at the Department of Physics of Milan University's congress on 28 and 29 June 2017, which was also intended as a kick-off meeting for the design of a novel science campus at the Expo site in Milan. The congress presented a snapshot of the department's research to the academic community, the media, policymakers and authorities as well as the public at large, and also provided an opportunity to strengthen interdisciplinary collaborations between the members of the department and other communities. This book is a valuable resource for scientists looking for synergetic projects, policymakers wanting to grasp scientists' points of view and for prospective graduate students seeking expanding areas of research.
