Название: An exact limit for the Peierls distortion energy in an antiferromagnetic chain by means of a renormalization procedure
Авторы: van de Braak H.P., Caspers W.J., Wiegel F.W.
Аннотация:
A renormalization procedure gives a rigorous upper bound for the ground-state energy per spin for a Peierls-distorted antiferromagnetic chain with Heisenberg interaction.
