Competition and cooperation among orders is at the heart of many-body physics in strongly
correlated materials and leads to their rich physical properties. It is crucial to investigate …

We investigate the altermagnetic properties of strongly-correlated transition metal oxides
considering the family of the quasi two-dimensional A 2 BO 4 and three-dimensional ABO 3 …

Ultrafast laser excitation provides a means to transiently realize long-range ordered
electronic states of matter that are hidden in thermal equilibrium. Recently, this approach …

We study the origin of the temperature-induced Mott transition in Ca 2 RuO 4. As a method
we use the local-density approximation+ dynamical mean-field theory. We show the …

We present and analyze Raman spectra of the Mott insulator Ca 2 RuO 4, whose quasi-two-
dimensional antiferromagnetic order has been described as a condensate of low-lying spin …

Accelerating the search for functional materials is a challenging problem. Here we develop
an informatics-guided ab initio approach to accelerate the design and discovery of …

The fate of a Mott insulator under strong low frequency optical driving conditions is a
fundamental problem in quantum many-body dynamics. Using ultrafast broadband optical …

In recent decades, novel magnetism of d-and f-electron compounds has been discussed
very intensively both in experimental and theoretical research fields of condensed matter …

We use Ru L 3-edge (2838.5 eV) resonant inelastic x-ray scattering (RIXS) to quantify the
electronic structure of Ca 2 RuO 4, a layered 4 d-electron compound that exhibits a …

We present first-principles studies on the orbital states of the layered perovskites Ca 2− x Sr
x RuO 4. The crossover from antiferromagnetic (AF) Mott insulator for x< 0.2 to nearly …
