...This Python package is centered around tensor train (TT, or matrix product) representations of quantum-mechanical Hamiltonian operators and (stationary or time-evolving) state vectors. WaveTrain builds on the Python tensor train toolbox scikit_tt, which provides efficient construction methods, storage schemes, as well as solvers for eigenvalue problems and linear differential equations in the TT format. WaveTrain comprises solvers for time-independent and time-dependent Schrödinger equations employing TT decompositions to construct low-rank representations. Often, the TT ranks of state vectors are found to depend only marginally on the chain length N, which results in the computational effort growing only slightly more than linearly in N, thus mitigating the curse of dimensionality.

Nanopuller by Konrad Pawlak and Janusz Strzelecki http://dx.doi.org/10.1016/j.ultramic.2016.01.008 http://www.biofizyka.fizyka.umk.pl/ Laboratory made AFM force spectroscopy setups were present in milestone single molecule experiments and there is a growing number of groups using such equipment even though the commercial setups are nowadays widely available. The ability to tailor the setup accordingly to particular application is an advantage that makes the effort necessary for construction a worthy investment. However, one advantage of using a commercial setup – repeatability and unification, cannot be archived, as every laboratory is developing a specific data acquisition protocol and software. Our Nanopuller software (open ISC license) presented here is intended to eliminate this obstacle. We give access to a program, which with only a minimum effort can be adjusted for vast array of typical equipment.

...Our development enables significant cost reduction (~300 €) and increase the availability of equibiaxial deformation measurements for scientific material analysis.

NanoCap is a generic application for the construction of low energy fullerene and capped nanotube structures. It provides an ideal tool to accompany the study of finite carbon molecules using computer simulation. The implementation involves a standalone application which includes a GUI and allows for dynamic visual inspection through 3D rendering. In addition, the NanoCap core libraries can be used in custom Python scripts that enabled the user to produce structures in bulk or to include the structure generation routines into pre-existing code.

This program allows you to create a transmission hologram using just a computer, a laser-printer, and an overhead transparency. This hologram will behave like one created using a laser and can be projected or viewed with a point source.
