Basic Ideas

The discovery of high temperature superconductivity has motivated a vigorous study of the physics of Hubbard systems. Here, the properties of the spin aspects of the Hubbard system in two-dimension, in the strong coupling limit, are briefly reviewed, with the basic ideas, some of the fundamental questions and the state of the art introduced.

Set Up

The formation of bound pair of electrons is studied using a t–J–U model on a two-dimensional honeycomb lattice for zero electron density. We set up the equations of motion (EOM) for two electrons in a two-sublattice basis and hence solve for the critical exchange coupling necessary to form a pair on a finite size lattice. The results extrapolated to the thermodynamic limit (N → ∞) and in the strong coupling regime (U / t → ∞) identifies Jc / t = 2. Calculation of binding energies at J = Jc provide support for the above result.

In this Chapter we address the physics of Bose-Einstein condensation and its implications to a driven-dissipative system such as the polariton laser. We discuss the dynamics of exciton-polaritons non-resonantly pumped within a microcavity in the strong coupling regime. It is shown how the stimulated scattering of exciton-polaritons leads to formation of bosonic condensates that may be stable at elevated temperatures, including room temperature.
