[hep-th] seminar

[Branislav Cvetkovic]

Postovane kolege,

u petak u 11 h na Institutu za fiziku u sali 300 u 11 h Nenad Manojlovic sa 
Univerziteta u Lisabonu ce odrzati seminar pod naslovom "Jordanian 
deformation of the open XXX-spin chain". U prilogu vam prosledjujem apstrakt 
seminara.

                                                     Pozdrav Branislav 

Abstract: We find the general solution of the reflection equation associated 
with the Jordanian deformation of the $SL(2)$-invariant Yang R-matrix. The 
special scaling limit of the XXZ model with general boundary conditions 
leads to the same K-matrix. Following the Sklyanin formalism, we derive the 
Hamiltonian with the boundary terms in explicit form. We also discuss the 
structure of the spectrum of the deformed XXX model and its dependence on 
the boundary conditions.
