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…
