Fluctuation pressure of a fluid membrane between walls through six loops
Boris Kastening
The fluctuation pressure that an infinitely extended fluid membrane exerts on two enclosing parallel hard walls is computed. Variational perturbation theory is used to extract the…
Novel Josephson Effect in Triplet Superconductor - Ferromagnet - Triplet Superconductor Junctions
Boris Kastening, Dirk K. Morr, Dirk Manske +1
We predict a novel type of Josephson effect to occur in triplet superconductor - ferromagnet - triplet superconductor Josephson junctions. We show that the Josephson current, I_J,…
Non-universal Critical Quantities from Variational Perturbation Theory and Their Application to the BEC Temperature Shift
Boris Kastening
For an O(N) symmetric scalar field theory with Euclidean action integral d^3x [1/2 |nabla phi|^2 + 1/2 r phi^2 + 1/4! u phi^4], where phi = (phi_1,...,phi_N) is a vector of N real…
Shift of BEC Temperature of Homogenous Weakly Interacting Bose Gas
Boris Kastening
We report on the computation of the shift of the Bose-Einstein condensation temperature for a homogenous weakly interacting Bose gas in leading order in the diluteness parameter a…
Bose-Einstein Condensation Temperature of Homogenous Weakly Interacting Bose Gas in Variational Perturbation Theory Through Seven Loops
Boris Kastening
The shift of the Bose-Einstein condensation temperature for a homogenous weakly interacting Bose gas in leading order in the scattering length `a' is computed for given particle de…
Bose-Einstein Condensation Temperature of Homogenous Weakly Interacting Bose Gas in Variational Perturbation Theory Through Six Loops
Boris Kastening
We compute the shift of the transition temperature for a homogenous weakly interacting Bose gas in leading order in the scattering length a for given particle density n. Using vari…
