All courses are expressed in the mathematical language typical of physics: differential calculus in one and several variables, complex numbers, algebra and statistics. They also include basic and advanced concepts of modern Physics (Mechanics, Thermodynamics, Electromagnetism and Quantum Mechanics) Calculation of atomic and molecular structure; ab-initio methods; variational and perturbative methods; calculation of atom-electron collisions; R-matrix method; cross-sections for excitation and ionization; resonances; calculation of atomic and molecular collisions; semi-classic approximations; classic CTMC methods.
