First-principles calculation of the instability leading to giant inverse magnetocaloric efects
Denis Comtesse, Markus E. Gruner, Vladimir V. Sokolovskiy +10
The structural and magnetic properties of functional Ni-Mn-Z (Z = Ga, In, Sn) Heusler alloys are studied by first-principles and Monte Carlo methods. The \textit{ab initio} calcula…
Anomalous vibrational effects in non-magnetic and magnetic Heusler alloys
A. T. Zayak, P. Entel, K. M. Rabe +2
First-principles calculations are used in order to investigate phonon anomalies in non-magnetic and magnetic Heusler alloys. Phonon dispersions for several systems in their cubic L…
Strong interaction of correlated electrons with phonons: Exchange of phonon clouds by polarons
V. A. Moskalenko, P. Entel, M. Marinaro +1
We investigate the interaction of strongly correlated electrons with phonons in the frame of the Hubbard-Holstein model. The electron-phonon interaction is considered to be strong…
Density functional simulation of small Fe nanoparticles
A. V. Postnikov, P. Entel, Jose M. Soler
We calculate from first principles the electronic structure, relaxation and magnetic moments in small Fe particles, applying the numerical local orbitals method in combination with…
Perturbation expansion for 2-D Hubbard model
V. Zlatic, B. Horvatic, B. Dolicki +3
We develop an efficient method to calculate the third-order corrections to the self-energy of the hole-doped two-dimensional Hubbard model in space-time representation. Using the D…
