Conditions for Efimov Physics for Finite Range Potentials
M. Thøgersen, D. V. Fedorov, A. S. Jensen +2
We consider a system of three identical bosons near a Feshbach resonance in the universal regime with large scattering length usually described by model independent zero-range pote…
Universality in Ultra-Cold Few- and Many-Boson Systems
Martin Thøgersen
This dissertation presents theoretical investigations of universality and finite-range corrections in few- and many-boson systems. The main focus is on ultra-cold atomic gases seen…
Thomas-Fermi Approximation for a Condensate with Higher-order Interactions
M. Thøgersen, N. T. Zinner, A. S. Jensen
We consider the ground state of a harmonically trapped Bose-Einstein condensate within the Gross-Pitaevskii theory including the effective-range corrections for a two-body zero-ran…
Stability of a BEC with Higher-order Interactions near a Feshbach Resonance
N. T. Zinner, M. Thøgersen
We consider the stability of an ultracold trapped Bose-Einstein condensate near a Feshbach resonance. Using a modified Gross-Pitaevskii equation that includes higher-order terms an…
Calculating few-body resonances using an oscillator trap
D. V. Fedorov, A. S. Jensen, M. Thøgersen
We investigate the possibility of calculating the parameters of few-body resonances using the oscillator trap boundary conditions. We place the few-body system in an oscillator tra…
