Infinitely dimensional Lax structure for one-dimensional Hubbard model
Vladislav Popkov, Tomaz Prosen
We report a two-parametric irreducible infinitely dimensional representation of the Lax integrability condition for the fermi Hubbard chain. Besides being of fundamental interest,…

Quasilocal conservation laws in XXZ spin-1/2 chains: open, periodic and twisted boundary conditions
Tomaz Prosen
A continuous family of quasilocal exact conservation laws is constructed in the anisotropic Heisenberg (XXZ) spin-1/2 chain for periodic (or twisted) boundary conditions and for a…

Observables and density matrices embedded in dual Hilbert spaces
T. Prosen, L. Martignon, T. H. Seligman
The introduction of operator states and of observables in various fields of quantum physics has raised questions about the mathematical structures of the corresponding spaces. In t…
