Researchers present revolutionary light-emitting silicon

Emitting light from silicon has been the Holy Grail in the microelectronics industry for decades. Solving this puzzle would revolutionize computing, as chips will become faster than ever. Researchers from Eindhoven University ...

Bubble dynamics reveal how to empty bottles faster

Bottle emptying is a phenomenon most of us have observed while pouring a beverage. Researchers from the Indian Institute of Technology Roorkee discovered how to make bottles empty faster, which has wide-ranging implications ...

Bethe strings experimentally observed

Ninety years ago, the physicist Hans Bethe postulated that unusual patterns, so-called Bethe strings, appear in certain magnetic solids. Now, an international team has succeeded in experimentally detecting such Bethe strings ...

Simulations show extreme opinions can lead to polarized groups

In recent years, chaos theory and other forms of computational modeling have sought to leverage findings in the social sciences to better describe—and maybe one day predict—how groups of people behave. One approach looks ...

Belle II yields the first results: In search of the Z′ boson

The Belle II experiment has been collecting data from physical measurements for about one year. After several years of rebuilding work, both the SuperKEKB electron–positron accelerator and the Belle II detector have been ...

Secure light-based communication through biological tissues

Visible light communications (VLC), and optical communications overall, caught professor Marcos Katz's interest when he and his team first demonstrated in 2017 a reconfigurable hybrid wireless network exploiting VLC and radio ...

A twist connecting magnetism and electronic-band topology

Materials that combine topological electronic properties and quantum magnetism are of high interest for the quantum many-body physics they exhibit and for possible applications in electronic components. ETH physicists have ...
