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 ...
Spin chains with non-diagonal boundaries and trigonometric SOS model with reflecting end
Spin chains non-diagonal boundaries trigonometric SOS model
2010/12/24
In this paper we consider two a priori very different problems: construction of the eigenstates of the spin chains with non parallel boundary magnetic fields and computation of the partition function ...
BPS Monopoles and Open Spin Chains
High Energy Physics - Theory (hep-th) Mathematical Physics (math-ph) Exactly Solvable and Integrable Systems (nlin.SI)

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...
Coherent state transfer via highly mixed quantum spin chains

Spin chains have been proposed as quantum wires in many quantum information processing architectures. Coherent transmission of quantum information over short distances is enabled by their internal dyn...
We discuss stochastic resonance-like effects in the context of coupled quantum spin systems. We focus here on an information-theoretic approach and analyze the steady state quantum correlations (entan...
