Hall coefficient of the t-J model

DC transport coefficients of most strongly interacting Hamiltonians demand insurmountable computational challenges, e.g. large system sizes, long real-time evolution, and poorly controlled analytic continuation of quantum Monte Carlo data. In contrast, it was shown that continued fractions expansions and the use of Hall-type resistivities, require only computations of equilbrium averages.
Here we use high temperature series and a continuted fraction expansion of the dynamical conductivity to calculate the Hall coefficeint of the t-J model.
