Sputter‐Grown MnBi2Te4 Thin Films: Magnetic Ground States and Phase Control

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
Magnetron sputtering enables the growth of smooth MnBi2Te4 thin films with reduced twinning and improved crystallinity. Bibby et al. systematically correlate composition, structure, and magnetic properties, revealing that excess Mn destabilizes the target phase, while even stoichiometric films exhibit suppressed interlayer coupling and weak magnetic ...

Cuprate Twistronics for Quantum Hardware

open access: yesAdvanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Beyond Kagome: p$p$‐Bands in Kagome Metals

open access: yesAdvanced Quantum Technologies, EarlyView.
Recent studies on quantum materials where transition‐metal atoms give rise to d$d$‐bands typical of kagome metals are reviewed. Using examples from several material families – AV3Sb5${\rm AV}_3{\rm Sb}_5$, FeGe, RV6Sn6${\rm RV}_6{\rm Sn}_6$, and LaRu3Si2${\rm LaRu}_3{\rm Si}_2$ – it is argued that p$p$‐bands contributed by elements beyond the kagome ...

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

open access: yesSmall, EarlyView.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.
