TL;DR

This paper analyzes the thermodynamic limit of gl(N) spin chains with arbitrary site representations, focusing on excited states and their energy corrections in large systems.

Contribution

It extends previous work by explicitly calculating corrections for excited states with holes and strings in the thermodynamic limit of gl(N) spin chains.

Findings

Derived formulas for density corrections of excitations

Computed energy corrections for excited states

Provided insights into the structure of excited states in large systems

Abstract

We consider the thermodynamical limit of a gl(N) spin chain with arbitrary representation at each site of the chain. We consider excitations (with holes and new strings) above the vacuum and compute their corrections in 1/L to the densities and the energy.
