We investigate the topological superconductor candidate UTe_{2} using high-resolution valence-band resonant inelastic x-ray scattering at the U M_{4,5} edges. We observe atomiclike low-energy excitations that support the correlated nature of this unc

There are few reports of ferroelectricity due to symmetry breaking transition in A-site-ordered quadruple perovskites. Here, the authors find one with phase transition from a high-temperature centrosymmetric paraelectric phase to a low-temperature no

It was hypothesized already more than 40 years ago that photoelectron spectroscopy should in principle be able to image atomic orbitals. If this can be made to work for orbitals in crystalline solids, one would have literally a different view on the
