Abstract: Abstract We consider two bosons in a one-dimensional harmonic trap, interacting by a contact potential, and compare the exact solution of this problem to a self-consistent numerical solution by using the multiconfigurational time-dependent Hartree (MCTDH)… read more here.

Abstract: We revisit the problem of choosing combinations of sources for multi-wavelength interferometry, using the risk of assigning the wrong integer interference order to a measured phase as a quantitative criterion. We model this risk, explicitly… read more here.

DOI: 10.1142/s021798492050356x
Abstract: We find a very simple scaling transformation method by which a kind of rank non-homogenous second order nonlinear ODEs is reduced to an integral form. Comparing with the canonical-like transformati... read more here.
