Split-step Fourier methods for the Gross-Pitaevskii equation
Juha Javanainen, Janne Ruostekoski
We perform a systematic study of the accuracy of split-step Fourier transform methods for the time dependent Gross-Pitaevskii equation using symbolic calculation. Provided the most…
Eigenstates and excitations of the simple atom-molecule Bose-Einstein condensate
Marijan Koštrun, Juha Javanainen
We model an atom-molecule Bose-Einstein condensate (AMBEC) using simplified set of coupled Gross-Pitaevskii equations (GPE), where we neglect the background (elastic) scattering le…
Mean-Field Theory of Feshbach-Resonant Interactions in 85Rb Condensates
Matt Mackie, Kalle-Antti Suominen, Juha Javanainen
Recent Feshbach-resonance experiments with 85Rb Bose-Einstein condensates have led to a host of unexplained results: dramatic losses of condensate atoms for an across-resonance swe…
Rate limit for photoassociation of a Bose-Einstein condensate
Juha Javanainen, Matt Mackie
We simulate numerically the photodissociation of molecules into noncondensate atom pairs that accompanies photoassociation of an atomic Bose-Einstein condensate into a molecular co…
Measurement theory for spinor condensates
Juha Javanainen
We study the experimental signatures of several states of a Bose-Einstein condensate of spin-1 atoms by quantum trajectory simulations of Stern-Gerlach experiments. The measurement…
