Many-body Theory




The many-body problem is usually posed in Quantum Mechanics , as the question of solving for more complex problems than the Hydrogen Atom — for example, the chemistry of all realistic Molecule s.

"It would indeed be remarkable if Nature fortified herself against further advances in knowledge behind the analytical difficulties of the many-body problem."

:- Max Born , 1960

The many-body problem may be defined as the study of the effects of interaction between bodies on the behaviour of a many-body system.
One of the preferred methods for solving the problem is simply to ignore it, i.e., pretend there are no interactions present.

Another approach is the Canonical Transformation Technique .
