Researchers design compact high-power laser using plasma optics

Lawrence Livermore National Laboratory (LLNL) researchers have designed a compact multi-petawatt laser that uses plasma transmission gratings to overcome the power limitations of conventional solid-state optical gratings. ...

From price shock to independence from fossil fuels

Oil and gas prices are currently on the rise, raising questions about the security of Switzerland's energy supply. In a policy brief, researchers from the Energy Science Center at ETH Zurich have now shown what Switzerland ...

Astronomers investigate highly variable polar V496 UMa

By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...

Finding coherence in quantum chaos

A theoretical breakthrough in understanding quantum chaos could open new paths into researching quantum information and quantum computing, many-body physics, black holes, and the still-elusive quantum to classical transition.

Halting a wave in its tracks

Topological ideas have recently taken the center stage of modern electromagnetics. Typical topological photonic systems are based on nonreciprocal materials, a class of materials that enables asymmetric light–matter interactions. ...
