...See https://github.com/ulflor/wavepacket for the follow-up project. WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry. ...

Zgoubi is a raytracing code. Since 1972 it pushes charged particles through accelerators and beam lines, by stepwise solution of Lorentz force equation - and their spins via Thomas-BMT differential equation. Zgoubi simulates beam dynamics and polarization in a variety of accelerators (storage ring, synchrotron, cyclotron, betatron, microtron, FFAG, multi-pass ERL, etc) and optical systems (beam lines, magnetic and electrostatic optical components, time-of-flight and mass spectrometers, etc). ...

WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, partly also classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. ...

...It models motion with a particle system and uses simple constraints and behaviors—such as gravity, attraction/repulsion, drag, and springs—to create believable movement with very little code. The design is intentionally composable: you attach behaviors to particles or groups and let the update loop integrate positions, producing emergent effects from a few rules. Because it is lightweight, it integrates easily with 2D renderers like Canvas or WebGL, and it is popular in generative art sketches and interactive experiments. The codebase emphasizes readability and hackability so learners can modify the solver, add new behaviors, or swap integrators without wading through engine internals. ...

WavePacket is a toolkit for numerical simulation of distinguishable particles. It can solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, as well as classical or quantum-classical Liouville equations. External electric fields can be added within the semiclassical dipole approximation, thus WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. ...

A toolkit in C++ and python to process both experimental and simulation data of colloidal particles. Includes among others * a multiscale particle tracking algorithm [1] whose C++ implementation is optimised for 3D confocal data. Python implementation is more versatile (2D and 3D data). * a Leica file reader, * Steindhard bond orientational order calculation * a VTK file writer 1. Leocmach, M. & Tanaka, H. A novel particle tracking method with individual particle size measurement and its application to ordering in glassy hard sphere colloids. ...

Physical simulation of particle movements. The computer program SphereSim simulates and animates the behavior and the movement of particles in a space. By forces (such as gravity in a particular direction and between the particles, repulsion of the particles against each other and from the walls, Lennard-Jones-Potential between particles) different physical effects in particle groups are calculated and shown, such as the Brownian motion. The application uses the programming language C++ and the Qt, OpenGL and OpenMP libraries.

Worldlines visualizes special relativity, as particles near lightspeed trace paths in a 3D slice of 4D Minkowski spacetime. Scenes illustrate time dilation, the twin paradox, length contraction, and Bell's spaceship paradox.

This library allows you to control a PMS (Particle Measuring Systems) Lasair II air particles counter. You can either use a COM component from several programming languages (Visual Basic, ...) or directly use its underlying Python class.

A program which simulates the motion of particles due to electric charge and gravitational force. Calculations are done in two dimensions, without care given to real world factors such as air resistance, although such functionality may be added later.
