9. Time-dependent Perturbation Theory
... So far we have been assuming that the perturbing wave is traveling in the +y direction with polarization in the z direction. But in fact we are interested in situations where the radiation comes in from all directions, and is polarized in all directions (allowed by its propagation direction). In or ...

Observation of the Pairing Gap in a Strongly Interacting Quantum... Fermionic Atoms
... The formation of composite bosons by pairing fermions leads to intriguing phenomena in physics, with superconductivity and He-3 superfluidity being prominent examples. In an ultracold gas of fermionic atoms, formation and condensation of diatomic molecules have been recently realized. This achieveme ...

... We then calculate the coefficients for the state after a third scattering ψ(3) (r ) = ψ(2) (r + rd), using the same logic as for the state ψ(2) (r ), and so on until we calculate the coefficients for an arbitrary number of interactions. The resulting general formula that gives the coefficients after ...
