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…
Ab initio electronic structure calculation of correlated systems: EMTO-DMFT approach
L. Chioncel, L. Vitos, I. A. Abrikosov +3
We propose a self-consistent method for electronic structure calculations of correlated systems, which combines the local spin-density approximation (LSDA) and the dynamical mean f…
Orbital Kondo behavior from dynamical structural defects
L. Borda, A. Zawadowski, G. Zarand
The interaction between an atom moving in a model double-well potential and the conduction electrons is treated using renormalization group methods in next-to-leading logarithmic o…
