SrCu2(BO3)2: A Unique Mott Hubbard Insulator
Abstract
We discuss the recently discovered system SrCu2(BO3)2, a realization of an exactly solvable model proposed two decades earlier. We propose its interpretation as a Mott Hubbard insulator. The possible superconducting phase arising from doping is explored, and its nature as well as its importance for testing the RVB theory of superconductivity are discussed.
