The mechanism of chemical bonding can be understood by describing the network of electronic interactions in material systems. However, its complexity is often high in such a way that the solution of ...

The quantum many body problem has been at the heart of much of theoretical and experimental physics over the past few decades. Even though we have understood the fundamental laws that govern the ...

Four lectures selected from those delivered at the Latin American School of Physics held at the University of Mexico, Jul.-Aug., 1965, and first published in 1967 under title: Many-body problems and ...

The three-body problem is a well-known challenge in physics. It envisions a minimalist universe with only three point masses moving under mutual gravitational interactions. Even in such a simplified ...
