Calculating energy shifts in terms of phase shifts
Zhenhua Yu, Gordon Baym, C. J. Pethick
To clarify the relation of energy shifts to scattering phase shifts in one-body and many-body problems, we examine their relation in a number of different situations. We derive, fo…

Clock shifts of optical transitions in ultracold atomic gases
Zhenhua Yu, C. J. Pethick
We calculate the shift, due to interatomic interactions, of an optical transition in an atomic Fermi gas trapped in an optical lattice, as in recent experiments of Campbell {\it et…

Induced interactions and the superfluid transition temperature in a three-component Fermi gas
J. -P. Martikainen, J. J. Kinnunen, P. Torma +1
We study many-body contributions to the effective interaction between fermions in a three-component Fermi mixture. We find that effective interactions induced by the third componen…
