Scientists observe 'quasiparticles' in classical systems for the first time

Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic world, while quantum physics explains the exotic behaviors of elementary particles in the microscopic world.

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 to unprecedented calculations of polarons in large systems, systematic studies of large sets of materials, and molecular dynamics evolving over long time periods.
