Quantum phase transitions and magnetization of an integrable spin ladder with new parameters in bridging to real compounds
Zu-Jian Ying, Itzhak Roditi, Huan-Qiang Zhou
We study the field-induced quantum phase transitions (QPT) and the relevant magnetic properties of a spin-1/2 two-leg integrable spin ladder (ISL), of which the system parameters i…
Effect of one-ion L-S coupling on magnetic properties of a correlated spin-orbit system
Zu-Jian Ying, Xi-Wen Guan, Angela Foerster +2
By introducing a basis for a novel realization of the SU(4) Lie algebra, we exactly solve a spin-orbital chain with one-ion - coupling (OILSC) via the Bethe ansatz (BA) appro…
First-order phase transitions in confined systems
C. A. Linhares, A. P. C. Malbouisson, I. Roditi
In a field-theoretical context, we consider the Euclidean model compactified in one of the spatial dimensions. We are able to determine the dependence of the transiti…
Charge and spin separation in the 1D Hubbard model
Vladimir E. Korepin, Itzhak Roditi
We consider the repulsive Hubbard model in one dimension and show the different mechanisms present in the charge and spin separation phenomena for an electron, at half filling and…
Quantum spin ladder systems associated with su(2|2)
A. Foerster, K. E. Hibberd, J. R. Links +1
Two integrable quantum spin ladder systems will be introduced associated with the fundamental su(2|2) solution of the Yang-Baxter equation. The first model is a generalized quantum…
