Virtual power plants offer a way forward for reliable and cost-effective power by combining rooftop solar and batteries. #climatechange #climatesolutions #climate

As rooftop solar gets hammered, virtual power plants offer a way forward
VPPs built out of home solar and battery systems could bolster the overtaxed power grid, lower energy costs for consumers, and help invigorate a…

Power-Law Interactions Stabilize Time Crystals Realizing Quantum Energy Storage and Sensing
We study discrete time-crystalline (DTC) phases in one-dimensional spin-1/2 chains with power-law interactions under periodic Floquet driving. By generalizing Stark localization to power-law interaction profiles, we identify robust period-doubled dynamics across a wide range of interaction exponents, stabilized by the interplay between coherent driving and spatially varying coupling. Within the DTC phase, the energy stored in the system, interpreted as a quantum battery, increases superlinearly…
