Classic DEVS modelling and simulation

2017 Winter Simulation Conference (WSC), 2017
Abstract: DEVS is a popular formalism for modelling complex dynamic systems using a discrete-event abstraction. At this abstraction level, a timed sequence of pertinent "events" input to a system (or internal, in the case of timeouts) cause instantaneous changes to the state of the system. Main advantages of DEVS are its rigorous formal definition, and

Classical Mechanics Simulations

Computers in Physics, 1996
Classical Mechanics Simulations is one of a series of nine comprehensive books that have been produced by the Consortium for Upper-Level Physics software (CUPS), which is funded by the United States National Science Foundation. They are intended to be used in conjunction with physics undergraduate courses.

Quon Classical Simulation: Unifying Clifford, Matchgates and Entanglement

arXiv.org
We propose a new framework of topological complexity to study the computational complexity of quantum circuits and tensor networks. Within this framework, we establish the Quon Classical Simulation (QCS) for hybrid Clifford-Matchgate circuits, which is ...

Electrostatics Interactions in Classical Simulations

2012
Electrostatic interactions are crucial for both the accuracy and performance of atomistic biomolecular simulations. In this chapter we review well-established methods and current developments aiming at efficiency and accuracy. Specifically, we review the classical Ewald summations, particle-particle particle-method particle-method Ewald algorithms ...

Displaced fermionic Gaussian states and their classical simulation

Journal of Physics A: Mathematical and Theoretical
This work explores displaced fermionic Gaussian operators with nonzero linear terms. We first demonstrate equivalence between several characterizations of displaced Gaussian states. We also provide an efficient classical simulation protocol for displaced

Theory and simulation of classical and quantum echoes

Physical Review E, 1996
Echo phenomena occurring in various physical systems are investigated, and analytical results are checked against computer experiments. It is found that Coulomb self-consistent interactions reduce the amplitude of the echo. Proof is given of the possibility of refocusing an initially localized packet by periodically kicking the particles, and the ...

Fast classical simulation of Harvard/QuEra IQP circuits

arXiv.org
Establishing an advantage for (white-box) computations by a quantum computer against its classical counterpart is currently a key goal for the quantum computation community.

Fast Classical Simulation of Quantum Circuits via Parametric Rewriting in the ZX-Calculus

QPL
The ZX-calculus is an algebraic formalism that allows quantum computations to be simplified via a small number of simple graphical rewrite rules. Recently, it was shown that, when combined with a family of"sum-over-Cliffords"techniques, the ZX-calculus ...

Simulating quantum dynamics in classical environments

Theoretical Chemistry Accounts: Theory, Computation, and Modeling (Theoretica Chimica Acta), 2003
Methods for simulating the dynamics of composite systems, where part of the system is treated quantum mechanically and its environment is treated classically, are discussed. Such quantum–classical systems arise in many physical contexts where certain degrees of freedom have an essential quantum character while the other degrees of freedom to which they

Simulation of Classical Fluids

1979
A concise review is given of Monte Carlo calculations for liquid systems, starting from hard-sphere models and Lennard-Jones fluids both in three and in two dimensions, and describing then ionic systems in detail; both fully ionized matter (i.e., dense plasmas) and electrolyte solutions, molten salts, etc. are treated.
