Laser probing of atomic Cooper pairs.

Physical review letters

Törmä P, Zoller P.
PMID: 10991322
Phys Rev Lett. 2000 Jul 17;85(3):487-90. doi: 10.1103/PhysRevLett.85.487.

We consider a gas of attractively interacting cold fermionic atoms which are manipulated by laser light. The laser induces a transition from an internal state with large negative scattering length to one with almost no interactions. The process can...

Beyond linear response spectroscopy of ultracold fermi gases.

Physical review letters

PMID: 16606063
Phys Rev Lett. 2006 Feb 24;96(7):070402. doi: 10.1103/PhysRevLett.96.070402. Epub 2006 Feb 22.

We study rf spectroscopy of ultracold Fermi gas by going beyond the linear response in the field-matter interaction. Higher order perturbation theory allows virtual processes and energy conservation beyond the single-particle level. We formulate an effective higher order theory,...
