While topoelectrical circuits are a successful tool for realizing various topological phases of matter, experiments mostly focus on detecting topological boundary phenomena originating from an underlying circuit Laplacian. Here, the authors introduce appropriate signal processing techniques that allow the recovery of the full spectrum of the chiral symmetric system from a single two-point impedance measurement. The robustness of these techniques is demonstrated by constructing the Fibonacci topoelectrical circuit for the first time, suggesting that topoelectrical circuits are an ideal metamaterial platform for studying different properties of quasi(crystalline) systems.

Much attention has been given to the spin-orbit coupling (SOC) effect on strongly correlated systems. Here, the authors investigate the electronic structure of the surface layer consisting of rotated RuO octahedrons in strongly correlated SrRuO. They demonstrate that the octahedral rotation generates small Fermi pockets. Furthermore, it enhances the strong correlation, which increases the effective SOC, causing high orbital mixing. This result reasonably explains why the orbital-selective Mott transition is not realized in perovskite oxides with crystal distortion of octahedral rotation and tilt.

The electronic excitations in solid molecular hydrogen at room temperature for pressures varying from 5 to 90 GPa are calculated using quantum Monte Carlo methods and many-body perturbation theory. A crossover from a wide-gap insulator to a semiconductor is observed, showing the changing nature of the excitations from localized molecular (left inset figure) to delocalized (right inset figure) excitations. These findings are in agreement with experimental results, demonstrating the capability of accurately predicting band gaps in many-body systems with strong zero point and thermal effects.

The authors implement here a setup for ultrahigh resolution measurements of x-ray Thomson scattering spectra, with a spectral range of several tens of eV. As an example, they study the Al plasmon and resolve longstanding discrepancies between simulations and experiments. By fully utilizing the capabilities of modern XFEL facilities, the setup opens up new avenues for the diagnosis of matter under extreme conditions, as they occur in inertial fusion energy applications and astrophysical objects.

Through a critical analysis of transport data from the recently discovered fractional quantum anomalous Hall effect (FQAHE) in rhombohedral pentalayer graphene on hBN, the authors identify here significant discrepancies between the FQAHE and the conventional fractional quantum Hall effect in Landau levels. Most notably, the excitation gap remains nearly constant for all observed fractions, starkly contrasting with the “v”-shaped linear dependence on |-1/2| predicted by the composite fermion model. This uncovers an intriguing puzzle regarding the nature of the FQAHE states.
