Condensed matter: Scratching the Bose surface
Subir Sachdev
Abstract
There are two distinct types of particles in nature: fermions and bosons. But it seems bosons may assume similar characteristics to fermion systems in the low-temperature regime typical of Bose–Einstein condensation.
Particles known as fermions (such as electrons) obey the Pauli exclusion principle, which decrees that only a single fermion can occupy a particular state, such as an orbital in an atom. But the second family of particles, bosons (such as helium atoms), have no corresponding restrictions on their occupation of states.
