Negative and positive charges attract each other, forming atoms, molecules and all that we often call matter. However, the negative charges repel each other, and in order to form atom-like bound objects, some extra glue is needed to compensate for this electrostatic repulsion and to bind particles together.

In this latest study, published in the journal Nature Physics, an international group, led by Professor Simone De Liberato from the School of Physics and Astronomy at the University of Southampton, demonstrated for the first time that photons, particles create light, which can be used to bind negative charges together, create a new form of matter they named Photon Bound Exciton.

Making a theoretical prediction published last year by the same team, Professor De Liberato and colleagues have fabricated a nanodevice that traps electrons into nano wells. They started by showing that photons hitting the device with sufficiently high energies had separated electrons from the well, an expected expression of the photoelectric effect, which his discovery earned Einstein the Nobel Prize. year 1921.

Professor De Liberato and his team then wrapped the device between two golden mirrors, which held the photons and concentrated the light energy close to the electrons, greatly increasing the interaction between light and matter. . They observed that a negatively charged electron that was ejected by a photon was then instead trapped in the well, bound to other negatively charged electrons in a new electron configuration stabilized by the photon. .

This result demonstrates the ability to create new artificial atoms in engineering with tailor-made electronic configurations, greatly expanding the list of materials available for science and technology applications.

Explaining the importance of his team’s discovery, Professor De Liberato said: “We have demonstrated how to use light as a subatomic ziptie, binding electrons together to create objects. In doing so we have expanded the portfolio of materials available to the design of photonics equipment.I look forward to seeing more of my colleagues working in the photonics field exploit the time period. This addition is about how to create new amazing devices. ”

The attempt to “explore matter at a pressure strong enough to change the nature of the atom itself,” as described by the center in the NSF award database. “Such conditions have not been explored or exploited on Earth, but they dominate inside planets and stars. To date, thousands of planets have been discovered, providing many viable platforms for life throughout the universe. To understand the origin, evolution, and nature of these planets, one must understand the properties of matter with a high energy density at and beyond atomic pressure.

Principal investigator Gilbert “Rip” Collins, Professor of Tracy / Hyde Engineering and said: “This effort will help explore the nature of the planets and stars in the universe, as well as the potential for states. New revolutionary state of matter on Earth. Physics and Astronomy, and deputy director of science, technology and academia at the Laser Generating Power Laboratory (LLE) at the University of Rochester.

Zurek, a chemistry professor at the College of Arts and Sciences, explains that most of the visible matter in the universe is subject to extreme conditions. “The properties of matter under these conditions control the evolution of planets and stars, but until recently, it was not possible to perform experimental calculations or research calculations,” she said. this degree. “Our work will do so, thus helping to create the most modern, next-generation planetary models.”

Zurek – an expert in theoretical chemistry and condensed matter physics – specializes in areas including computational chemistry and high pressure. Among other contributions, her team will perform calculations that will help researchers understand the structure of the planetary components – the compounds that make up planets – at extremely high pressures and temperatures.
