Universality classes of order parameters composed of many body bound states

29 Nov 2016 Tsvelik A. M.

This theoretical paper discusses microscopic models giving rise to special types of order in which conduction electrons are bound together with localized spins to create composite order parameters. It is shown that composite order is related to the formation of a spin liquid with gapped excitations carrying quantum numbers which are a fraction of those of electron... (read more)
