The "Square Kagome" Quantum Antiferromagnet and the Eight Vertex Model
Rahul Siddharthan, Antoine Georges
We introduce a two dimensional network of corner-sharing triangles with square lattice symmetry. Properties of magnetic systems here should be similar to those on the kagome lattic…

Ordering and partial ordering in holmium titanate and related systems
R. Siddharthan, B. S. Shastry, A. P. Ramirez
We take another look at two compounds which have been discussed as possible realizations of ``spin ice'', namely holmium titanate and dysprosium titanate. As we have earlier observ…

The Quantum Toda Lattice Revisited
Rahul Siddharthan, B. Sriram Shastry
In this work we study the quantum Toda lattice, developing the asymptotic Bethe ansatz method first used by Sutherland. Despite its known limitations we find, on comparing with Gut…
