2D Nondirect Product Discrete Variable Representation for Schrödinger Equation with Nonseparable Angular Variables
Sara Shadmehri, Shahpoor Saeidian, Vladimir S. Melezhik
We develop a nondirect product discrete variable representation (npDVR) for treating quantum dynamical problems which involve nonseparable angular variables. The npDVR basis is con…

Confinement-Induced Resonances in Two-Center Problem via Pseudopotential Approach
Sara Shadmehri, Vladimir S. Melezhik
We study confined scattering of a quantum particle by two centers fixed on the longitudinal axis of a harmonic waveguide-like trap. The conditions of confinement-induced resonances…

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…
