We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and...

Interactive program to perform quantum transport calculations by means of the Landauer and scattering matrix formalism, in a two terminal geometry. The Hamiltonians of leads and scattering region can be modified, adding exchange fields, mass, spin-orbit coupling or superconductivity.

Python library to perform electronic structure calculations with tight binding models in different types of lattices and different dimensionalities. It allows to include different terms in the Hamiltonian as sublattice, exchange field or magnetic field. Provides functions to calculate different Green functions, band structure, density of states, transport using Landauer formula, topological invariants, etc.

User friendly interface for calculating electronic properties in graphene-like ribbons. The programs uses the tight binding approximation and mean field Hubbard model to predict electronic properties of graphene-like nanoribbons. See Discussion to ask questions or details Update: New versions of this program will be known as quantum-honeycomp

...At variance with other approaches, it is possible to analyse also processes in solution, e.g., chemical reactions in liquid water, since the distance metric is based on a Permutation Invariant Vector (PIV) that is symmetric under exchange of identical atoms or molecules, including on the same footing both solute and solvent degrees of freedom. The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. ...

PLASMAKIN is a package to handle physical and chemical data used in plasma physics modeling and to compute gas-phase and gas-surface kinetics data: particle production and loss rates, photon emission spectra and energy exchange rates.
