Franco Nori at the Center for Emergent Matter Science (CEMS), RIKEN (Japan). January 2017: We were pleased to be invited speakers at the workshop "Virtual photons in ultra-strongly coupled system" organized by the Condensed Matter Reasearch Group directed by Prof. The film has been screened around the world, from Glasgow to Singapore. The film Approaching Reality, produced by our group has been selected as a finalist for the Quantum Short film festival, receiveing an honorable mention of the jury. March 2018: We are pleased to announce vacancies for a PhD student and a post-doctoral researcher to join the group, see Join Us for details. This work experimentally demonstrated phonon-mediated scattering between intersubband polaritons, an effect I had theoretically predicted almost ten years ago! Our recent paper Applied Physics Letters 112, 191106 (2018) was chosen as Featured Paper. Theoretical prediction verified after ten years. We demonstrated that when the coupling becomes non-perturbative, the standard Rabi and Dicke models dramatically fail to describe the system dynamics, predicting unphysical phenomena as the possibility to transmit information faster than light. To celebrate the new journal this review will remain open access for one year.ĭr Simone De Liberato won the 2018 Philip Leverhulme Prize in physics.įaster than light! Dr Simone De Liberato and his coworkers investigated relativistic effects in non-perturbative cavity quantum electrodynamics: Nature Communicati(2018). Review on Ultrastrong coupling between light and matter was published, as first paper ever, by the new journal Nature Reviews Physics. This discovery is an important milestone toward the realization of a novel generation of electrically pumped mid-infrared devices. The results have recently been published in Nature Communicati(2019).

Together with our experimental colleagues at Vanderbilt and LMU, we theoretically predicted and experimentally observed novel quasiparticles we named Longitudinal-Transverse Phonon Polaritons.

This theory allows us to simulate the crystalline dynamics of atom-size objects without requiring cumbersome numerical approaches. Our paper developing a theory of nonlocal optical response in polar dielectrics has been published in Physical Review X 10, 021027 (2020). Viewpoint on Physics: Physics, the showcase journal of the Americas Physical Society, dedicated a Viewpoint to our recent paper: A. May 2020: Congratulations to Erika Cortese, who successfully defended her PhD thesis on "Tuning Materials' properties by non-perturbative Cavity Quantum Electrodynamics". June 2020: Congratulations to Erika Cortese, who has been awarded the Runner-Up of the Faculty of Engineering and Physical Sciences with topic "Understanding of nonperturbative light-matter coupling in nanostructures" from Doctoral College Research Awards. We are also interested in public engagement activities aimed at widening the societal understanding of quantum mechanics. The Quantum Theory and Technology group investigates quantum phenomena in solid-state systems, with particular interest for their possible applications, both in nanophotonics and in the expanding field of quantum technologies. We are part of the University of Southampton Quantum Light Matter group. Welcome to the Quantum Theory and Technology group website.
