, 2011 String theory has transformed our understanding of geometry, topology and spacetime. Thus, for this special issue of Foundations of Physics commemorating "Forty Years of String Theory", it seems appropriate to step back and ask what we do not understand.

Microlasers Made Entirely from Edible Substances
Advanced Optical Materials, EarlyView.Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Exotic branes in Exceptional Field Theory: the SL(5) duality group
Journal of High Energy Physics, 2018 We study how exotic branes, i.e. branes whose tensions are proportional to g s − α , with α > 2, are realised in Exceptional Field Theory (EFT). The generalised torsion of the Weitzenböck connection of the SL(5) EFT which, in the language of gauged ...

Advanced Sensor Research, EarlyView.A wearable capacitive eye tracker for chronic fatigue assessment is presented, utilizing cylindrically shaped capacitive sensors made of a carbon nanotube‐paper composite. By integrating a novel fatigue‐induction protocol with machine learning, the device achieves 0.75‐sensitivity and 0.73‐specificity, providing a practical alternative to existing ...

Energy Symmetry Breaking of Dirac and Weyl Fermions in Magnetized Spinning Conical Geometries
Advanced Theory and Simulations, EarlyView.Exact solutions for relativistic fermions in magnetized, spinning conical geometries reveal defect‐induced symmetry breaking between fermion and antifermion energies. Energy levels depend on the magnetic field, background geometry, and fractionalized spin. When the defect's spin dominates, quantum effects diminish.

Two-loop scattering amplitudes: double-forward limit and colour-kinematics duality
Journal of High Energy Physics, 2019 We propose new formulae for the two-loop n-point D-dimensional integrands of scattering amplitudes in Yang-Mills theory and gravity. The loop integrands are written as a double-forward limit of tree-level trivalent diagrams, and are inferred from the ...
