PD Dr. Rer. Nat. Alexej I. Streltsov
I did manage to transform a bright theoretical idea to a final high-tech scientific product – MCTDHB-Laboratory: http://qdlab.org
MCTDHB-Lab is a free scientific cross-platform (Win/Mac/Linux) environment with a mouse-click interface designed to solve
Time-Dependent Schrödinger Equation for bosons based on Multi-Configurational Time-Dependent Hartree for Bosons method .
This is the result of effective inter-communications and inter-actions of many involved people, whom I have coherently driven towards the final result.
