Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

open access: yesAdvanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Luminescence Spectra Simulation of Ce3+‐Activated Phosphors by Accumulating Emission Lines Along First‐Principles Molecular Dynamics Trajectories

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
A density functional theory‐based method is introduced to predict the luminescence emission spectra of candidate compounds, including broadening caused by atomic thermal motion. For each snapshot from the molecular dynamics of the Ce‐activated system using the excited‐state electron configuration, the transition energies and probabilities are ...

Lifshitz Transition in Correlated Topological Semimetals

open access: yesAdvanced Science, Volume 13, Issue 31, 4 June 2026.
Theoretical calculations reveal that in YPtBi and GdPtBi, strong electronic correlations shift topological Dirac nodes away from the Fermi level by forming large hole pockets. This effect is sensitive to temperature and arises from interactions among 4d or 4f electrons, offering insights into Fermi surface engineering in quantum materials.
