Generalized mean field description of entanglement in dimerized spin systems
A. Boette, R. Rossignoli, N. Canosa +1
We discuss a generalized self-consistent mean field (MF) treatment, based on the selection of an arbitrary subset of operators for representing the system density matrix, and its a…

Phase diagram study of a dimerized spin-S zig-zag ladder
J. M. Matera, C. A. Lamas
The phase diagram of a frustrated spin- zig-zag ladder is studied through different numerical and analytical methods. We show that for arbitrary , there is a family of Hamilt…
