10 June 2020 is #Strike4BlackLives and we urge you to participate in this strike. Organised by a group of physicists, led by Brian Nord and Chanda Prescod-Weinstein, this is a day to #ShutDownAcademia and #ShutDownSTEM in solidarity with Black colleagues, Black students and Black people who are excluded from academia. Learn more about the strike here.  Read more

Behind the paper: CP violation in neutrino oscillations

In 1967, Andrei Sakharov proposed conditions required in the early universe for generating matter and anti-matter at different rates, to explain the abundance of matter in our universe today. Charge-Parity (CP) violating processes are essential under these conditions. Measurements of the CP violation in quarks, first performed in 1964, are too small to explain the difference, and finding other sources of CP violation is an ongoing quest in the physics community. In April 2020, the T2K collaboration published a paper in Nature suggesting large CP violation in the leptonic sector, namely in neutrino oscillations. Some of the researchers involved in the project tell us their story.  Read more

What’s in our browser tabs? August 2019

Welcome to our new monthly link round-up! As editors of physics journals, we love reading the latest research papers, but we also love a bit of lunch-break popular science reading. Here are some pieces that caught our eyes in August:  … Read more

Interactions: Chen Fang and the Materiae database

Interactions: Chen Fang and the Materiae database

In theory, many ordinary materials can have exotic topological phases. But how can we find them? In 2018 a research group from the National Laboratory for Condensed Matter Physics in Beijing scanned 39519 materials to predict which phases of the already-known compounds might exhibit topological properties. These materials were summarised into an interactive database Materiae, where you can browse compounds containing particular elements, check if they have any topological phases and visualise their band structure.  Read more

What is physics? Challenges and opportunities when working at the interface with other disciplines.

What is physics? Challenges and opportunities when working at the interface with other disciplines.

This year’s Berlin Science Week kicked off with a diverse programme. Among many events, visitors could discuss the connection between art and astronomy or learn how new technologies can be inspired by nature, or participate in a panel discussion at the Springer Nature office. The panellists set out to find an answer on how we define physics today, and to map out the boundaries with other related areas such as chemistry or biology.  Read more

X-rays : a tale of bones, molecules and mummies

X-rays are the portion of the electromagnetic spectrum that falls between gamma rays and the ultraviolet (UV) — their wavelength is of the order 0.01−10 nanometres. What’s fascinating about them is their extremely wide range of applications, going from astronomy to art.  Read more

Interactions: Conversation with Philip Ball

Interactions: Conversation with Philip Ball

Philip Ball talks about his latest book “Beyond Weird” — an exploration of the meanings of quantum theory and a tale of a continued effort to make sense of it. Call it counter-intuitive, challenging or puzzling — just don’t call it weird.  Read more
