Spin-S Kitaev model: Classical Ground States, Order by Disorder and Exact Correlation Functions
G. Baskaran, Diptiman Sen, R. Shankar
In the first part of this paper, we study the spin-S Kitaev model using spin wave theory. We discover a remarkable geometry of the minimum energy surface in the N-spin space. The c…

Exact Haldane mapping for all and super universality in spin chains
A. M. M. Pruisken, R. Shankar, N. Surendran
The low energy dynamics of the anti-ferromagnetic Heisenberg spin chain in the semiclassical limit is known to map onto the O(3) nonlinear model with a ter…

Exact results for spin dynamics and fractionization in the Kitaev Model
G. Baskaran, Saptarshi Mandal, R. Shankar
We present certain exact analytical results for dynamical spin correlation functions in the Kitaev Model. It is the first result of its kind in non-trivial quantum spin models. The…
