Local boundary conditions for NMR-relaxation in digitized porous media
M. Ogren
We narrow the gap between simulations of nuclear magnetic resonance dynamics on digital domains (such as CT-images) and measurements in D-dimensional porous media. We point out wit…
Faraday waves in quasi-one-dimensional superfluid Fermi-Bose mixtures
F. Kh. Abdullaev, M. Ogren, M. P. Soerensen
Generation of Faraday waves in superfluid Fermi-Bose mixtures in elongated traps is investigated. The generation of waves is achieved by periodically changing a parameter of the sy…
Atom-atom correlations in colliding Bose-Einstein condensates
Magnus Ogren, K. V. Kheruntsyan
We analyze atom-atom correlations in the s-wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for…
Superfluidity in a gas of strongly-interacting bosons
G. M. Kavoulakis, Y. Yu, M. Ogren +1
We consider small systems of bosonic atoms rotating in a toroidal trap. Using the method of exact numerical diagonalization of the many-body Hamiltonian, we examine the transition…
Supershell structure in trapped dilute Fermi gases
Y. Yu, M. Ogren, S. Aberg +2
We show that a dilute harmonically trapped two-component gas of fermionic atoms with a weak repulsive interaction has a pronounced super-shell structure: the shell fillings due to…
