Tunable lattice Induced Opacity in atom-lattice interaction
Chen Zhang, Chris H. Greene
A lattice-induced opacity is identified in the scattering process of a normally-incident matter wave from a two dimensional lattice of atoms. This system can be treated as an analo…
Extension of the correlated Gaussian hyperspherical method to more particles and dimensions
Kevin M. Daily, Chris H. Greene
The solution of the hyperangular Schrödinger equation for few-body systems using a basis of explicitly correlated Gaussians remains numerically challenging. This is in part due to…
Quasi-1D scattering with general transverse 2D confinement
Chen Zhang, Chris H. Greene
Confinement induced resonances (CIR) in quasi-1D systems have been theoretically predicted and observed in various ultracold atomic gases. Here a regularized local frame transforma…
Stochastic and equilibrium pictures of the ultracold FFR molecular conversion rate
Tomotake Yamakoshi, Shinichi Watanabe, Chen Zhang +1
The ultracold molecular conversion rate occurring in an adiabatic ramp through a Fano-Feshbach resonance is studied and compared in two statistical models. One model, the so-called…
Lorentz meets Fano spectral line shapes: A universal phase and its laser control
Christian Ott, Andreas Kaldun, Philipp Raith +6
Symmetric Lorentzian and asymmetric Fano line shapes are fundamental spectroscopic signatures that quantify the structural and dynamical properties of nuclei, atoms, molecules, and…
Quantum Defect Theory for High Partial Wave Cold Collisions
Brandon P. Ruzic, Chris H. Greene, John L. Bohn
We extend Multichannel Quantum Defect Theory (MQDT) to ultracold collisions involving high partial wave quantum numbers . This requires a careful standardization of the MQDT ref…
