Oscillating quasiparticles: the cycle of decay and rebirth

The concept of quasiparticles was coined by Nobel laureate Lev Davidovich Landau, who used it to describe collective states of lots of particles or rather their interactions due to electrical or magnetic forces. Due to this interaction, several particles act like one single one.The assumption has been that quasiparticles in interacting quantum systems decay after a certain time but the opposite is the case, according to a recent paper: strong interactions can even stop decay entirely. Collective lattice vibrations in crystals, so-called phonons, are one example of such quasiparticles.read more

Oscillating quasiparticles: the cycle of decay and rebirth

Decay is relentless in the macroscopic world: Broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: New research shows that so-called ...
