A configuration interaction approach to solve the Anderson impurity model; applications to elemental Ce
Basile Herzog, Patrik Thunström, Olle Eriksson
Accurate calculations of strongly correlated materials remain a formidable challenge in condensed matter physics, particularly due to the computational demand of conventional metho…
Dynamical electronic correlation and chiral magnetism in van der Waals magnet Fe4GeTe2
Md. Nur Hasan, Nastaran Salehi, Felix Sorgenfrei +7
Among the quasi-2D van der Waals magnetic systems, Fe4GeTe2 imprints a profound impact due to its near-room temperature ferromagnetic behaviour and the complex magnetothermal phase…
Microscopic effect of spin-lattice couplings on dynamical magnetic interactions of a skyrmion system PdFe/Ir(111)
Banasree Sadhukhan, Anders Bergman, Johan Hellsvik +2
PdFe/Ir(111) has attracted tremendous attention for next-generation spintronics devices due to existence of magnetic skyrmions with the external magnetic field. Our density functio…
Generic optical excitations of correlated systems: -tons
Anna Kauch, Petra Pudleiner, Katharina Astleithner +3
The interaction of light with solids gives rise to new bosonic quasiparticles, with the exciton being---undoubtedly---the most famous of these polaritons. While excitons are the ge…
Parquet approximation for molecules: spectrum and optical conductivity of the Pariser-Parr-Pople model
Petra Pudleiner, Patrik Thunström, Angelo Valli +3
We study a simple model system for the conjugated -bonds in benzene, the Pariser-Parr-Pople (PPP) model, within the parquet approximation (PA), exemplifying the prospects of the…
A systematic study of the local minima in L(S)DA+U
Samara Keshavarz, Patrik Thunström
We have performed a systematic study of the emergence of meta-stable states in density functional theory plus Hubbard U (DFT+U ) simulations of NiO, CoO, FeO. Particular attention…
