Below the transition temperature the presence of a spatially inhomogeneous order parameter gap shifts up the excitation eigenenergies and leads to the appearance of in gap excitations localized in the outer part of the gas sample. A new fractional schrödinger equation is constructed from path integral based on the notions of fractional velocity recently introduced in literature and the concept of fractional actionlike.

With the help of variational perturbation theory we continue the renormalization constants of φ 4 theories in 4 dimensions to infinitely strong bare couplings g 0 and find their power behavior in g 0 thereby determining all critical exponents without the standard renormalization group techniques. We reveal a strong influence of a superfluid phase transition on the character of single particle excitations of a trapped neutral atom fermi gas.

Using variational perturbation theory we calculate the shift in the critical temperature tc up to five loops to lowest order in the scattering length a and find delta t c t c 0 approx 1 14.

We present a method for extracting tunnelling amplitudes from perturbation expansions which are always divergent and not borel summable.
