New research reveals the characteristics of positronium formation within football-shaped nanoparticles, C60, for the first time. At specific positron impact energies, the study shows that positronium ...

Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported. Black holes ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Quantum field theories are powerful tools for particle physics and condensed matter physics but are rarely used in plasma physics. However, in warm-dense regimes, where matter is partially ionized and ...

Recent advances in laser technology have enabled the exploration of previously inaccessible regimes where electrons interact with ultra-intense electromagnetic fields. These interactions drive ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

A proton (far left) from the Super Proton Synchrotron (SPS) accelerator at CERN impinges on carbon nuclei (small gray spheres). This produces a shower of various elementary particles, including a ...

When electrons collide with positrons, their antimatter counterparts, unstable pairs can form in which both types of particle orbit around each other. Named 'positronium', physicists have now produced ...
