This episode of the Physics World Weekly podcast features the materials scientist Paul Meredith, who is director of the Centre for Integrative Semiconductor Materials (CISM) at the UK’s Swansea University. In a conversation with Physics World’s Matin Durrani, Meredith talks about the importance of semiconductors in a hi-tech economy and why it is crucial for the UK to have a homegrown semiconductor industry. Founded in 2020, CISM moved into a new, state-of-the-art £50m building in 2023 and is now in its first full year of operation. Meredith explains how technological innovation and skills training at CSIM is supporting chipmakers in the M4 hi-tech corridor, which begins in Swansea in South Wales and stretches eastward to London.

This podcast features Alonso Gutierrez, who is chief of medical physics at the Miami Cancer Institute in the US. In a wide-ranging conversation with Physics World’s Tami Freeman, Gutierrez talks about his experience using Elekta’s Leksell Gamma Knife for radiosurgery in a busy radiotherapy department. This podcast is sponsored by Elekta.

Panicos Kyriacou, chief scientist at Crainio and professor of engineering, is pioneering a non-invasive optical sensor for measuring intracranial pressure, a critical factor in diagnosing brain injuries. He discusses the limitations of invasive methods and the urgent need for efficient, non-invasive alternatives. Kyriacou explains how the sensor uses light and machine learning to monitor blood flow in real-time, potentially revolutionizing brain injury assessments both in clinical settings and emergency situations.

This episode of the Physics World Weekly podcast features William Phillips, who shared the 1997 Nobel Prize for Physics for his work on cooling and trapping atoms using laser light. In a wide-ranging conversation with Physics World’s Margaret Harris, Phillips talks about his long-time fascination with quantum physics – which began with an undergraduate project on electron spin resonance. Phillips chats about quirky quantum phenomena such as entanglement and superposition and explains how they are exploited in atomic clocks and quantum computing. He also looks to the future of quantum technologies and stresses the importance of curiosity-led research. Phillips has spent much of his career at US’s National Institute for Standards and Technology (NIST) in Maryland and he also a professor of physics at the University of Maryland.   This podcast is supported by Atlas Technologies, specialists in custom aluminium and titanium vacuum chambers as well as bonded bimetal flanges and fittings used everywhere from physics labs to semiconductor fabs.

Last week I had the pleasure of attending the Global Physics Summit (GPS) in Anaheim California, where I rubbed shoulders with 15,0000 fellow physicists. The best part of being there was chatting with lots of different people, and in this podcast I share two of those conversations. First up is Chetan Nayak, who is a senior researcher at Microsoft’s Station Q quantum computing research centre here in California. In February, Nayak and colleagues claimed a breakthrough in the development of topological quantum bits (qubits) based on Majorana zero modes. In principle, such qubits could enable the development of practical quantum computers, but not all physicists were convinced, and the announcement remains controversial – despite further results presented by Nayak in a packed session at the GPS. I caught up with Nayak after his talk and asked him about the challenges of achieving Microsoft’s goal of a superconductor-based topological qubit. That conversation is the first segment of today’s podcast. Distinctive jumping technique Up next, I chat with Atharva Lele about the physics of manu jumping, which is a competitive aquatic sport that originates from the Māori and Pasifika peoples of New Zealand. Jumpers are judged by the height of their splash when they enter the water, and the best competitors use a very distinctive technique. Lele is an undergraduate student at the Georgia Institute of Technology in the US, and is part of team that analysed manu techniques in a series of clever experiments that included plunging robots. He explains how to make a winning manu jump while avoiding the pain of a belly flop.

Artur Ekert, a theoretical crypto-physicist from Oxford and Singapore, dives into the world of quantum cryptography inspired by giants like Einstein and Bell. He explains the historical significance of the EPR paradox and how Bell’s theorem revolutionized secure communication methods. The conversation highlights the transformative experiments that validated these theories, the challenges in quantum communication security, and the promising advancements in quantum computation. Ekert’s insights illuminate the philosophical implications of quantum mechanics and the pursuit of randomness.

Ileana Silvestre Patallo is a medical physicist at the UK's National Physical Laboratory, and Ruth McLauchlan is a consultant radiotherapy physicist at Imperial College Healthcare NHS Trust. They dive into the dual nature of ionizing radiation, detailing how it can both harm and heal. The discussion covers the precision of radiotherapy in targeting cancer cells while protecting healthy tissue, the evolution of treatment techniques, and exciting innovations like flash radiotherapy. They emphasize the importance of technology in improving patient outcomes.
