Dynamical mean-field theory for dense spin systems at finite temperature
This work develops Dynamical Mean-Field Theory for spin systems (spinDMFT) to treat dense, interacting spins at finite temperatures using a time-dependent mean field. The method uses imaginary time evolution to find dynamical correlations. It is exact in limits where the lattice becomes infinite-dimensional or interactions are infinitely long-ranged, making it useful for single-site theory applications.
