We show that time-reversal symmetry-broken, centrosymmetric antiferromagnets with
nonrelativistic spin splitting of d-wave symmetry—the so-called d-wave altermagnets—are …

We use symmetry analysis and density-functional theory to determine and characterize
surface terminations that have a finite equilibrium magnetization density in antiferromagnetic …

We present a method to constrain local charge multipoles within density-functional theory.
Such multipoles quantify the anisotropy of the local charge distribution around atomic sites …

Motivated by the recent discovery of odd-parity multipolar antiferromagnetic order in CeRh 2
As 2, we examine the coexistence of such translation invariant Kramers' degenerate …

Resonant inelastic x-ray scattering (RIXS) has become a prominent technique to study
quasiparticle excitations. With advances in polarization analysis capabilities at different …

In this thesis, I study correlated materials, specifically transition-metal oxides with a
perovskite or double-perovskite structure. In the considered materials–CaFeO₃ …

In this work, we consider the interplay of different magnetic orders and superconductivity. We
consider both phenomenological and microscopic models to capture these interactions. The …
