Quantum dot (QD) lasers enable intrinsically feedback-tolerant, isolator-free silicon photonic integrated circuits (PICs), eliminating the bulky optical isolators traditionally required to suppress ...

The microscopic origin of line tension, used in the equilibrium description of liquid drops on flat surfaces, is not well understood. Simulations of water nanodroplets show that structural transitions ...

PM-in-waiting Andy Burnham plans to give more power to UK cities and regions, which raise only 8% of tax ⁠revenues versus a 37% rich-country average. But decentralisation elsewhere has proven better ...
