Ultrafast electron crystallography reveals the atomic pathway of a light-driven correlated insulator-to-metal transition
Arthur Niedermayr, Hongyi Xu, Chin Shen Ong +9
Ultrafast phase transitions in correlated materials are often inferred from selected diffraction peak intensities or diffraction peak displacements, leaving the underlying three-di…
Non-equilibrium THz-phonon spin coupling in CrI3
V Shokeen, M Pavelka, R Chulkov +8
Manipulating magnetism at the THz timescale in atomically thin ferromagnets by exploiting the interactions of spins with optical phonon modes presents an innovative idea for THz sp…
Ultrafast manipulation of the NiO antiferromagnetic order via sub-gap optical excitation
Xiaocui Wang, Robin Y. Engel, Igor Vaskivskyi +19
Wide-band-gap insulators such as NiO offer the exciting prospect of coherently manipulating electronic correlations with strong optical fields. Contrary to metals where rapid depha…
Electronic and Magnetic Properties of single Fe atoms on a CuN Surface; Effects of Electron Correlations
S. K. Panda, I. Di Marco, O. Grånäs +2
The electronic structure and magnetic properties of a single Fe adatom on a CuN surface have been studied using density functional theory in the local spin density approximation (L…
Analytic continuation by averaging Padé approximants
J. Schött, I. L. M. Locht, E. Lundin +3
The ill-posed analytic continuation problem for Green's functions and self-energies is investigated by revisiting the Padé approximants technique. We propose to remedy the well-kno…
Non-trivial order parameter in SrIrO
Shreemoyee Ganguly, Oscar Granas, Lars Nordstrom
Electronic structure calculations obtained with an approach with density functional theory with an enhanced local Coulomb interaction, DFT+, are presented for the relativistic m…
Electronic structure, cohesive properties and magnetism of SrRuO; a theoretical investigation
Oscar Grånäs, Igor di Marco, Olle Eriksson +2
We have performed an extensive test of the ability of density functional theory within several approximations for the exchange-correlation functional, local density approximation+H…
Charge self-consistent dynamical mean-field theory based on the full-potential linear muffin-tin orbital method: methodology and applications
O. Grånäs, I. Di Marco, P. Thunström +4
Full charge self-consistence (CSC) over the electron density has been implemented into the local density approximation plus dynamical mean-field theory (LDA+DMFT) scheme based on a…
Itinerant magnetic multipole moments of rank five, triakontadipoles, as the hidden order in URuSi
Francesco Crichhio, fredrik Bultmark, Oscar Granas +1
A broken symmetry ground state without any magnetic moments has been calculated by means of local-density-approximation to density functional theory plus a local exchange term, the…
Multipole decomposition of LDA+ energy and its application to actinides compounds
Fredrik Bultmark, Francesco Cricchio, Oscar Grånäs +1
A general reformulation of the exchange energy of -shell is applied in the analysis of the magnetic structure of various actinides compounds in the framework of LDA+U method. T…
