Exactly solvable D_N-type quantum spin models with long-range interaction
B. Basu-Mallick, F. Finkel, A. Gonzalez-Lopez
We derive the spectra of the D_N-type Calogero (rational) su(m) spin model, including the degeneracy factors of all energy levels. By taking the strong coupling limit of this model…
An exactly solvable supersymmetric spin chain of BC_N type
J. C. Barba, F. Finkel, A. Gonzalez-Lopez +1
We construct a new exactly solvable supersymmetric spin chain related to the BC_N extended root system, which includes as a particular case the BC_N version of the Polychronakos-Fr…
The Berry-Tabor conjecture for spin chains of Haldane-Shastry type
J. C. Barba, F. Finkel, A. Gonzalez-Lopez +1
According to a long-standing conjecture of Berry and Tabor, the distribution of the spacings between consecutive levels of a "generic'' integrable model should follow Poisson's law…
The Polychronakos-Frahm spin chain of BC_N type and Berry-Tabor's conjecture
J. C. Barba, F. Finkel, A. Gonzalez-Lopez +1
We compute the partition function of the su(m) Polychronakos-Frahm spin chain of BC_N type by means of the freezing trick. We use this partition function to study several statistic…
