Unconventional Superfluidity in a model of Fermi-Bose Mixtures
K. Sheshadri, A. Chainani
A finite-temperature () study of a model of a mixture of spin-zero hardcore bosons and spinless fermions, with filling fractions and , respectively, on a two-dimens…
Frustration effects and role of selective exchange coupling for magnetic ordering in the Cairo pentagonal lattice
A. Chainani, K. Sheshadri
The Cairo pentagonal lattice, consisting of an irregular pentagonal tiling of magnetic ions on two inequivalent sites (3- and 4-co-ordinated ones), represents a fascinating example…
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…
