Abstract
I would like to discuss two questions which deal with the nature of elementary excitations in well-defined condensedmatter systems. The first question is, ‘Can a system made up of particles each of which have integer charge (± e) have excitations on fractional charge Q = ± ve without violating quantum echanics?’ The second question is, ‘Can a system of particles interacting with forces which are invariant under space and time inversion have excitations which can move in only a single direction?’ The answer to both of these questions is affirmative. It is interesting to see how these peculiar results come about in specific cases.
