A Unified Algebraic Approach to Few and Many-Body Hamiltonians having Linear Spectra
N. Gurappa, Prasanta K. Panigrahi, T. Soloman Raju
We develop an algebraic approach for finding the eigenfunctions of a large class of few and many-body Hamiltonians, in one and higher dimensions, having linear spectra. The method…
