SUMMARY:Séminaire du LPTMS: Lenart Zadnik - LPTMS\, salle 201\, 2ème éta
 ge\, Bât 100\, Campus d'Orsay - 11 Juin 19 11:00
DESCRIPTION:Inhomogeneous matrix product ansatz and exact solutions for str
 ongly boundary driven spin chains\nLenart Zadnik (University of Ljubljana)
 \nI will present a novel inhomogeneous Lax structure and demonstrate the e
 xact solvability of a dissipatively boundary driven XYZ spin-1/2 chain in 
 the limit of strong dissipation. I will describe the explicit inhomogeneou
 s matrix product ansatz for the nonequilibrium steady state of the problem
 . The constituent matrices of this ansatz satisfy a simple set of linear r
 ecurrence relations. Although they can be embedded into an infinite-dimens
 ional auxiliary space\, they cannot be simultaneously put into a tridiagon
 al form\, not even in the case of axially symmetric (XXZ) bulk interaction
 s and general nonlongitudinal boundary dissipation. The results are expect
 ed to have further fundamental applications for the construction of nonloc
 al integrals of motion for the open XYZ model with arbitrary boundary fiel
 ds.
