WebAbstract: In the absence of frustration, interacting bosons in the ground state exist either in the superfluid or insulating phases. Superfluidity corresponds to frictionless flow of the matter field, and in optical conductivity is revealed through a distinct $\delta$-functional peak at zero frequency with the amplitude known as the Drude weight. A product state of the Fock space is a state of the form which describes a collection of particles, one of which has quantum state , another and so on up to the th particle, where each is any state from the single particle Hilbert space . Here juxtaposition (writing the single particle kets side by side, without the ) is symmetric (resp. antisymmetric) multiplication in the symmetric (antisymmetric) tensor algebra.

WebThe most general Fock state is a linear superposition of pure states. Two operators of great importance are the creation and annihilation operators, which upon acting on a Fock state add or respectively remove a particle in the ascribed quantum state. They are denoted for creation and for annihilation respectively.

When stirred, a superfluid forms vortices that continue to rotate indefinitely. Superfluidity occurs in two isotopes of helium ( helium-3 and helium-4) when they are liquefied by cooling to cryogenic temperatures.
