Parallels Between Quantum Antiferromagnetism and the Strong Interactions
R. B. Laughlin
I argue that there is a connection between quantum antiferromagnetism and the strong interactions. The underlying idea is that the t-J Hamiltonian and other models commonly studied…

Quantum Number Fractionalization in Antiferromagnets
R. B. Laughlin, D. Giuliano, R. Caracciolo +1
This is a pedagogical introduction to the mathematics of 1-dimensional spin-1/2 antiferromagnets. Topics covered include the Haldane-Shastry Hamiltonian, vector ``supercharges'', c…
