Optical coherent perfect absorption and amplification in a time-varying medium - Nature Photonics The researchers show that a subwavelength film of indium tin oxide, the bulk permittivity of which is strategically modulated via optical pumping, can be dynamically tuned to act as both a non-resonan...

News from the lab! 🤩
Is it possible to switch a material from being an absorber to an amplifier just by changing the phase of light?
By treating a thin film of ITO as a time-varying medium, we achieved 400% amplification and 80% absorption within the same structure.

A more focused research system does not by itself solve structural deficits Anton Muscatelli and Miles Padgett think through the deeper issues in UK research – from cost recovery and dual support to doctoral training and organisational structure – that won’t be solved by simp...

Riccardo Sapienza - Metamaterials that vary in time unlock superluminal motion YouTube video by Aula Rostagni UniPadova DFA

It was a great honor to step on the "aula Rostagni" @unipd.bsky.social Università degli Studi di Padova, and give a talk, in the same place where 25 years before I was defending my MSci thesis... If you had asked me then I would never have guessed that

It is a confusing topic because usually is thought before Fourier optics. If done after it is quite natural

Bridging the gap between scientists, policy makers and industry to build the quantum ecosystem – Physics World Elizabeth Pasatembou and Dimitrie Cielecki discuss their experience of doing science policy engagement during their PhDs

The life of a PhD student is not only in the lab, Dimitrie has explored the boundary between innovation, technology and policy. All this while completing his PhD last week! 🍾
