At the edge of a phase transition in certain quantum materials, electrons can enter an exotic “strange metal” state, where they cease behaving like well-defined quasiparticles. The authors investigate here whether this state, in an isotropic system, is internally stable against perturbations with different angular momenta. By developing a theoretical framework to trace collective electron oscillations through the crossover from a Fermi liquid to a non-Fermi liquid regime, the authors demonstrate that the system remains stable under perturbations with all angular momenta — including the odd-momentum modes whose stability was previously questioned.

The authors consider here the evolution of the Fano combs in the light scattering spectra on dielectric resonators under perturbations of the resonator shape (α) and excitation conditions (φ). The precise theory of electromagnetic Fano resonances and microwave experiments demonstrate that in the proximity of special points in the parametric space (α,φ), the Fano asymmetry q of a particular resonant line can reach any value under an appropriate perturbation, providing effective control of light interference in the far field.

Symmetry and topology are two key concepts in condensed matter physics. Here, the authors reveal a hidden stacking-dependent band topology in twisted double bilayer graphene (TDBG), showing the distinct topological properties of ABBA- and ABAB-TDBG in the dispersive band limits by measuring Landau level spectra and the gap at the charge neutral point. They further demonstrate a topological transition in ABAB-TDBG from trivial to nontrivial that is driven by electrical field-induced symmetry breaking, thus revealing an intimate connection between symmetry and topology.
