This is a comprehensive study of the Ru-based Kitaev honeycomb compound (H,Li)RuO (HLRO), combining magnetization (), magnetic specific heat (), and local probes (muon spin relaxation and magnetic resonance). There is clear evidence of a Kitaev quantum spin liquid (KQSL) state. , , and magnetic fluctuations (1/) exhibit scaling behavior. The scaling is in good agreement with theory [PRX 11, 011034 (2021)]. A two-step entropy release is taken as a signature of Majorana fermions. HLRO is a realization of a KQSL without magnetic order in zero field, unlike 𝛼-RuCl.

Motivated by recent experiments on atomically thin transition metal dichalcogenides (TMDs), the authors explore here the role of electron-phonon coupling in the location of the fluid-to-liquid transition point of electrons. They highlight that phonons (illustrated as the blue background) can gain more energy when electrons form a Wigner crystal compared to when they are in a liquid state. Their findings demonstrate that this effect significantly affects TMDs and other atomically thin materials, while its impact remains negligible in quantum wells. This is consistent with previous experimental results.

The spin polarization of a boundary flat band (BFB) protected by chiral symmetry is typically fixed. The authors experimentally demonstrate here the realization of BFBs with momentum-dependent spin polarizations, exhibiting nontrivial topological windings across the boundary Brillouin zone in a circuit system. The so-called subchiral symmetry is the key symmetry responsible for the emergence of these additional topological properties. These findings establish BFBs as a promising new platform for exploring flat-band physics.

Interactions and fluctuations can drastically change the nature of phases and phase transitions in electronic materials. Here, the authors provide numerical evidence for a continuous quantum phase transition between a normal metal and a crystalline insulator, which challenges physicists’ standard theories for quantum phase transitions and demands novel explanations. Inspired by experiments in moiré quantum simulators and using sophisticated numerics, the authors study the transition from a crystal of spatially separated electron pairs to a metal as the interaction strength is reduced at a fixed low filling.
