Reentrant stability of BEC standing wave patterns
Ryan M. Kalas, Dmitry Solenov, Eddy Timmermans
We describe standing wave patterns induced by an attractive finite-ranged external potential inside a large Bose-Einstein Condensate (BEC). As the potential depth increases, the ti…
Odd-frequency pairing in a binary mixture of bosonic and fermionic cold atoms
Ryan M. Kalas, Alexander V. Balatsky, Dmitry Mozyrsky
We study fermionic superfluidity in a boson-single-species-fermion cold atom mixture. We argue that apart from the standard p-wave fermion pairing mediated by the phonon field of t…
Dilute Bose gases interacting via power-law potentials
Ryan M. Kalas, D. Blume
Neutral atoms interact through a van der Waals potential which asymptotically falls off as r^{-6}. In ultracold gases, this interaction can be described to a good approximation by…
Equation of state of atomic systems beyond s-wave determined by the lowest order constrained variational method: Large scattering length limit
Ryan M. Kalas, D. Blume
Dilute Fermi systems with large s-wave scattering length a_s exhibit universal properties if the interparticle spacing r_o greatly exceeds the range of the underlying two-body inte…
Ground-state properties of a large Coulomb-blockaded quantum dot
Eugene B. Kolomeisky, Michael Timmins, Ryan M. Kalas
Using renormalization-group techniques we analyze equilibrium properties of a large gated quantum dot coupled via a long and narrow channel to a reservoir of electrons. Treating th…
Interaction-Induced Localization of an Impurity in a Trapped Bose Condensate
Ryan M. Kalas, D. Blume
We study the ground state properties of a trapped Bose condensate with a neutral impurity. By varying the strength of the attractive atom-impurity interactions the degree of locali…
