Quantum spin models with exact dimer ground states

Brijesh Kumar

Inspired by the exact solution of the Majumdar-Ghosh model, a family of one-dimensional, translationally invariant spin hamiltonians is constructed. The exchange coupling in these…

$S r C u_{2} (B O_{3})_{2}$ : A Unique Mott Hubbard Insulator

B Sriram Shastry, Brijesh Kumar

We discuss the recently discovered system $S r C u_{2} (B O_{3})_{2}$ , a realization of an exactly solvable model proposed two decades earlier. We propose its interpretation as a Mott Hubba…
