Chemistry – A European Journal, EarlyView.A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.

Deep Learning Spinfoam Vertex Amplitudes: The Euclidean Barrett–Crane Model
UniverseSpinfoam theories propose a well-defined path-integral formulation for quantum gravity, and it is hoped that they will provide the dynamics of loop quantum gravity. However, it is computationally hard to calculate spinfoam amplitudes.

Few‐Photon Fluorescence From Ultracold Bosons in an Optical Cavity
Contributions to Plasma Physics, EarlyView.ABSTRACT Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second‐harmonic generation (SHG) regimes. Two settings are considered: (i) (few) bosons in an optical lattice and (ii) a trapped two‐component dilute Bose–Einstein condensate (2BEC) within the Bogoliubov scheme.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Gravitational axial anomaly, stochastic matter production, and leptogenesis
European Physical Journal C: Particles and FieldsPartially chiral stochastic gravitational wave backgrounds can arise from various processes in the early Universe. The gravitational ABJ anomaly links the chirality of the gravitational field to the chiral fermions, resulting in the stochastic generation
