Phases and Transitions in the Spin-1 Bose-Hubbard Model: Systematics of a Mean-field Theory
Ramesh V. Pai, K. Sheshadri, Rahul Pandit
We generalize the mean-field theory for the spinless Bose-Hubbard model to account for the different types of superfluid phases that can arise in the spin-1 case. In particular, ou…

Suppression of Magnetic Frustration by Doping in a nearest-neighbour anti-ferromagnetic triangular lattice
K. Sheshadri, A. Chainani
Based on experimental observations in A{x}MO{2} (A = Na, Li; M = Co, Ni), a model for suppression of magnetic frustration by electron doping in a nearest-neighbour antiferromagneti…

Theory of Size-Driven Transitions in Displacive and Order-Disorder Ferroelectrics
K. Sheshadri, Rangan Lahiri Pushan Ayyub, Shobo Bhattacharya
We present a simple theory for structural transitions in displacive ferroelectrics of the perovskite type. In our theory, the competition between the elastic energy cost for the di…
