How quantum bound states bounce and the structure it reveals | | Dean Lee

31 Aug 2010 | | Abstract: | We investigate how quantum bound states bounce from a hard surface. Our
analysis has applications to ab initio calculations of nuclear structure and
elastic deformation, energy levels of excitons in semiconductor quantum dots
and wells, and cold atomic few-body systems on optical lattices with sharp
boundaries. We develop the general theory of elastic reflection for a composite
body from a hard wall. On the numerical side we present universal results for
two-body states and discuss ab initio calculations for general few-body
systems. On the analytical side we derive a universal effective potential that
gives the reflection scattering length for shallow two-body states. | | Source: | arXiv, 1008.5187 | | Services: | Forum | Review | PDF | Favorites | |
