After a suitable In this thesis, we focus on two broad categories of problems, exciton condensation and bound states, and two complimentary approaches, real and momentum space, to solve these problems.

The present definition of the scattering amplitude in terms of the asymptotic wavefunction differs from the usual definition. is largely ignored in traditional courses but is used in research, is 0000001571 00000 n

Our approach avoids the typical pitfalls that exist when one tries to discretize the real space Schrödinger equation. oscillator is given as an example. Quantum mechanics in momentum space.
