The multilayer cuprates host the highest superconducting transition temperature while their underlying physical mechanism remains unclear. By employing large-scale dynamical cluster quantum Monte Carlo simulations, the authors show here that the trilayer Hubbard model, with a realistic doping distribution within three layers, exhibits a higher than the single-layer model. This work also provides strong numerical evidence on the possibility of -wave superconductivity solely hosted in the inner layer.

The authors challenge a long-standing view of TaNiSe as an excitonic insulator by revealing a nonexcitonic origin for its phase transitions. Using systematic density functional theory calculations across the TaNi(Se,S) series, they show that structural distortions and charge doping account for the observed metal-insulator transitions. The calculations explain measured angle-resolved photoemission spectra with excellent accuracy, reconciling conflicting experimental observations and establishing a lattice-driven mechanism for the transitions in this system.

The surface photovoltaic effect (SPV) is extensively utilized in optoelectronic devices including ultraviolet/infrared photodetectors, ambient light sensors, and specific solar cell configurations. It enables the conversion of light energy into electrical signals or electrical power by inducing a surface potential difference in materials upon illumination. The authors demonstrate here an ultrahigh sensitive SPV in NbSiTe under low-illumination and low-temperature conditions, while stronger infrared illumination suppresses SPV via the Dember effect. Temperature-dependent measurements reveal that the ultrahigh photoresponse arises as bulk carrier freezing at low temperatures enables minute photoexcited carriers to dominate. The work also highlights an observer effect in ARPES measurements, where the probing itself alters the system’s original state.
Zero-flux localization: Magic flat bands via non-Abelian gauge fields

Solving a longstanding puzzle, the authors give here an exact account of magic flat bands at zero net magnetic flux. They present closed-form wavefunctions and recast moiré “magic” as a special case of zero-flux localization. A single real-space criterion enforced by a non-Abelian spin field guarantees perfect flatness. Remarkably, the solution is clear enough for graduate-level homework and serves as a springboard toward strongly correlated phases in zero-flux settings.
