Acceleration and twisting of neutral atoms by strong elliptically polarized short-wavelength laser pulses
Vladimir S. Melezhik, Sara Shadmehri
We have investigated non-dipole effects in the interaction of a hydrogen atom with elliptically polarized laser pulses of intensity 10 W/cm with about 8 fs duration. The…
Improving Efficiency of Sympathetic Cooling in Atom-Ion and Atom-Atom Confined Collisions
Vladimir S. Melezhik
We propose a new way for sympathetic cooling of ions in an electromagnetic Paul trap: it implies the use for this purpose of cold buffer atoms in the region of atom-ion confinement…
Impact of ion motion on atom-ion confinement-induced resonances in hybrid traps
Vladimir S. Melezhik, Zbigniew Idziaszek, Antonio Negretti
We investigate confinement-induced resonances in atom-ion quantum mixtures confined in hybrid traps. Specifically, we consider an ion confined in a time-dependent radio-frequency P…
Low-Dimensional Few-Body Processes in Confined Geometry of Atomic and Hybrid Atom-Ion Traps
Vladimir S. Melezhik
We have developed an efficient approach for treating low-dimensional few-body processes in confined geometry of atomic and hybrid atom-ion traps. It based on the split-operator met…
Tunneling of two bosonic atoms from a one-dimensional anharmonic trap
I. S. Ishmukhamedov, V. S. Melezhik
We investigate the quantum dynamics of two interacting bosonic atoms confined in a one-dimensional anharmonic trap. The tunneling rate, an experimentally measurable parameter of th…
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…
