Matrix Product State (MPS) Simulations
Numerical routines for variational matrix product state simulations.
Open Source MPS (OSMPS) is a collection of numerical routines for performing tensor network algorithms to simulate entangled, 1D many-body quantum systems. Our applications reach from ground state and excited states for statics to the dynamics of time-dependent Hamiltonians. We offer various time evolution methods with an emphasis on the support of long-range interactions through the matrix product state formalism. For more algorithms, see the list of features below. -

Sensitizer
A toolset to automate STOP analysis with Zemax OpticStudio
...The core data structure of SENSITIZER is an optical group, which can be any optical surface in the lens file or a set of subsequent surfaces. These groups will be perturbed by varying their positions relative to the rest of the system (rigid-body-motions) and/or by adding Zernike shape deformations on their front surface. After a certain perturbation is applied, ZOS runs (sequential) raytracing to compute the optical performance such as centroid displacement or wavefront error. -

Time-Evolving Block Decimation
TEBD simulates the dynamics of entangled quantum many-body systems.
Time-Evolving Block Decimation (TEBD) is a new method for efficiently simulating the dynamics of entangled quantum many-body systems. It is especially suited to one-dimensional systems governed by a Hamiltonian made of local interactions. Open Source TEBD is a package, written in Fortran 95, which allows one to simulate the entangled quantum dynamics of a one-dimensional system governed by a Hamiltonian made of local interactions using TEBD. Expectation values and correlation functions, as well as entanglement measures and entropies, can be calculated. ... -

Lagrange Rally 3D
3D vehicle simulator based on Lagrangian dynamics to simulate dynamics
3D vehicle simulator in which vechicle's configuration as a whole (articulated body) , is represented by a 'vector' of generalised coordinates. so concepts like usual position and orientation of main body and wheels is all defined by the generalised coordinates.Using Lagrangian dynamics, theese coordinates are evolving in time in a realistic manner according to F=ma but as if there were also all constraint forces concretasing the presence of joints: hinge, prismatic, rigid connection, etc. all derivatives are done with finite differences, so it's all simple. in 3 videos I explain all the mechanics and its simulation up to this simple but pow method.Pure Lagrangian mechanics until now has not been used much or at all,in simulation videogames,but i decided to try it because it was promising, very simple compared to the fnal results, and there was not much docu on its use in simulation games: this lack was completed now. ... -
