Finite temperature properties and frustrated ferromagnetism in a square lattice Heisenberg model
Nic Shannon, Burkhard Schmidt, Karlo Penc +1
The spin 1/2 Heisenberg model on a square lattice with antiferromagnetic nearest- and next-nearest neighbour interactions (the -- model) has long been studied as a paradi…

General spectral function expressions of a 1D correlated model
J. M. P. Carmelo, K. Penc
We introduce a method that allows the evaluation of general expressions for the spectral functions of the one-dimensional Hubbard model for all values of the on-site electronic rep…

Finite-Energy Pseudoparticle Theory for the 1D Hubbard Model II: Holon and Spinon Dominant Processes for the Few-Electron Spectral Weight Properties
J. M. P. Carmelo, K. Penc
In the first paper of this series it was found that the -spin 1/2 holons, spin 1/2 spinons, and pseudoparticles whose occupancy configurations describe the energy eigenstate…
