String hypothesis for gl(n|m) spin chains: a particle/hole democracy
String hypothesis gl(n|m) spin chains particle/hole democracy
2011/3/3
This paper is devoted to integrable gl(n|m) spin chains which allow for for-mulation of the string hypothesis. Considering the thermodynamic limit of such spin chains, we derive linear functional equa...
Topological term in the non-linear $\sigma$ model of the SO(5) spin chains
Non-linear sigma model topological terms spin chains

We show that there is a topological (Berry phase) term in the non-linear model description of the SO(5) spin chain. It distinguishes the linear and projective repre-sentations of the SO(5) symmetry ...
BPS Monopoles and Open Spin Chains

We construct SU(n+1) BPS monopoles with minimal symmetry breaking by solving the full Weyl equation. In this context, we explore and discuss the existence of an open spin chain-like part within the We...
