An exotic atom is where one or more of the normal subatomic particles (protons, neutrons, and electrons) have been replaced with an ‘alternative’. For example, if we replace the proton in hydrogen with a positron we form positronium, the quasi-stable short-lived bound state of the positron and electron. The exotic atoms group works with positrons and antiprotons to make systems including positronium and antihydrogen (a bound positron and antiproton).  

By studying exotic atoms, we can probe matter-antimatter interactions, search for symmetry violation and hence probe physics beyond the standard model at low energies using ‘relatively’ small experiments.
