Investigation of Confinement Induced Resonance in Atomic Waveguides with Different Geometries by Quantum Monte Carlo Methods
Sajad Azizi, Shahpoor Saeidian
We have investigated the quantum dynamics of two ultracold bosons inside an atomic waveguide for two different confinement geometries (cigar-shaped and toroidal waveguides) by quan…
Multichannel Scattering and Loss Processes of Ultracold Atoms in Anisotropic Harmonic Waveguides
Sara Shadmehri, Shahpoor Saeidian, Vladimir S. Melezhik
We have developed the general grid method for multi-channel scattering of bosonic atoms inside a harmonic waveguide with transverse anisotropy. This approach is employed to analyze…
Shifts and widths of Feshbach resonances in atomic waveguides
Shahpoor Saeidian, Vladimir S. Melezhik, Peter Schmelcher
We develop and analyze a theoretical model which yields the shifts and widths of Feshbach resonances in an atomic waveguide. It is based on a multichannel approach for confinement-…
Multi-Channel Atomic Scattering and Confinement-Induced Resonances in Waveguides
Shahpoor Saeidian, Vladimir S. Melezhik, Peter Schmelcher
We develop a grid method for multi-channel scattering of atoms in a waveguide with harmonic confinement. This approach is employed to extensively analyze the transverse excitations…
Atomic hyperfine resonances in a magnetic quadrupole field
Shahpoor Saeidian, Igor Lesanovsky, Peter Schmelcher
The quantum resonances of an atom possessing a single valence electron which shows hyperfine interaction with the nucleus is investigated in the presence of a three dimensional mag…
Negative Energy Resonances of Bosons in a Magnetic Quadrupole Trap
Shahpoor Saeidian, Igor Lesanovsky, Peter Schmelcher
We investigate resonances of spin 1 bosons in a three-dimensional magnetic quadrupole field. Complementary to the well-known positive energy resonances it is shown that there exist…
