Spin Driven Jahn-Teller Distortion in a Pyrochlore system
Yasufumi Yamashita, Kazuo Ueda
The ground-state properties of the spin-1 antiferromagnetic Heisenberg model on the corner-sharing tetrahedra, pyrochlore lattice, is investigated. By breaking up each spin into a…

New valence bond crystal phase of a frustrated spin-1/2 square lattice antiferromagnet
M. E. Zhitomirsky, Kazuo Ueda
We propose a new type of magnetically disordered ground state for a frustrated quantum antiferromagnet. This disordered state is an array of spin singlets spontaneously formed on f…
