Probing quantum correlations in many-body systems: a review of scalable methods

In a recently study published in Reports on Progress in Physics, researchers Irénée Frérot, Matteo Fadel and ICREA Prof. at ICFO Maciej Lewenstein, review methods that allow one to detect and characterize quantum correlations in many-body systems, with a special focus on approaches which are scalable. Maciej Lewenstein gives a brief overview about the study in the following […]

Revealing novel quantum behaviour of electrons in solids

In a recent study in Nature, an international team of researchers demonstrates theoretically and experimentally the capabilities that solid-state simulators could have in reproducing peculiar states of matter by mimicking electronic behaviour and observing their outcomes. Quantum simulation with excitons Simple Quantum-Mechanical Models To describe matter on a microscopic level, physicists rely on very simple […]

Jens Biegert interviewed by OPTICA

What is attosecond science, and how is it used? Optica Fellow Jens Biegert, ICFO, Spain, explains how the field unravels how things work inside materials using ultrashort laser pulses. If you enjoyed this glimpse into the world of attosecond science, dive deeper into the cutting edge of optics and photonics research on the Optica YouTube […]

Ein Photon rein, zwei Elektronen raus – Pro Physik

Ein Photon rein, zwei Elektronen raus https://pro-physik.de/nachrichten/ein-photon-rein-zwei-elektronen-raus Exzitonenspaltung für die Entwicklung hocheffizienter Photovoltaik. Die Photovoltaik ist eine Schlüssel­technologie für eine nachhaltige Energie­versorgung. Bei nur wenigen molekularen Materialien wie Pentacen wird ein Photon in zwei Elektronen umgewandelt. Diese Anregungs­verdopplung, die als Exzitonenspaltung bezeichnet wird, könnte für die Entwicklung hocheffizienter Photovoltaik äußerst nützlich sein, insbesondere um die […]

Exciton fission – one photon in, two electrons out – ScienceMag

Exciton Fission Breakthrough: Revolutionizing High-Efficiency Photovoltaics Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. In fact, since the days of Max Planck and Albert Einstein, we have known that both light and electricity are quantized, meaning they come in tiny packets called photons and electrons. In a typical solar […]

Exciton fission – one photon in, two electrons out – SpaceDaily

Exciton fission – one photon in, two electrons out by Staff Writers Berlin, Germany (SPX) May 07, 2023 Unraveling the Mystery of Exciton Fission “When pentacene is excited by light, the electrons in the material rapidly react,” explains Prof. Ralph Ernstorfer, a senior author of the study. “It was an open and very disputed question […]
