Is there a multiverse?

Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her journey to connect with ...

Strong microwave magnetic fields for more efficient plasmas

Hot gases composed of metal ions and electrons, called plasmas, are widely used in many manufacturing processes, chemical synthesis, and metal extraction from ores and welding. A collaborative research group from Tohoku University ...

Using the shadows of clusters to measure the universe

Astronomers have begun using a sophisticated suite of simulations, an advanced machine learning model of the formation of galaxy clusters, and an exotic relationship between galaxies to understand the origins of dark matter ...

Nickel nanowires enhance microwave absorption, study finds

In a study published in Advanced Materials Interfaces, a research team led by Prof. Wang Hui and associate Prof. Sheng Zhigao from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences reported ...

Photonic chip with record-breaking radio frequency dynamic range

Researchers at the University of Twente have developed a revolutionary programmable integrated microwave photonic filter with a record-breaking dynamic range. This represents a major breakthrough in the integration of functionality ...

A diamond-based quantum amplifier

In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin ...
