Observing the birth of a quasiparticle

Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances ...

Stabilizing polarons opens up new physics

Physicists at EPFL have developed a formulation to solve the longstanding problem of electron self-interaction when studying polarons—quasiparticles produced by electron-phonon interactions in materials. The work can lead ...

How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ...
