Signals from antimatter

This month, we chat about antimatter. A recent experiment probing antiprotonic helium (a helium atom where one of the electrons is replaced by an antiproton) found an unexpected result. Rather than spectral lines broadening as the temperature of the system was lowered, the spectral lines got sharper! Tune in to find out more...

Featuring Masaki Hori (Max Planck Institute of Quantum Optics) and Federico Levi (Nature)

Hosted by Ankita Anirban (Nature Reviews Physics) and Cristiano Matricardi (Nature communications)
