Quantum spins on star graphs and the Kondo model
Nicolas Crampe, Andrea Trombettoni
We study the XX model for quantum spins on the star graph with three legs (i.e., on a Y-junction). By performing a Jordan-Wigner transformation supplemented by the introduction of…

Integrable Models From Twisted Half Loop Algebras
Nicolas Crampe, Charles A. S. Young
This paper is devoted to the construction of new integrable quantum mechanical models based on certain subalgebras of the half loop algebra of gl(N). Various results about these su…

Bethe Equations for a g_2 Model
N. Crampe, C. A. S. Young
We prove, using the coordinate Bethe ansatz, the exact solvability of a model of three particles whose point-like interactions are determined by the root system of g_2. The statist…
