Two-channel Bose-Hubbard model of atoms at a Feshbach resonance
Philipp-Immanuel Schneider, Alejandro Saenz
Based on the analytic model of Feshbach resonances in harmonic traps described in Phys. Rev. A 83, 030701 (2011) a Bose-Hubbard model is introduced that provides an accurate descri…
Non-perturbative theoretical description of two atoms in an optical lattice with time-dependent perturbations
Philipp-Immanuel Schneider, Sergey Grishkevich, Alejandro Saenz
A theoretical approach for a non-perturbative dynamical description of two interacting atoms in an optical lattice potential is introduced. The approach builds upon the stationary…
Quantum computation with ultracold atoms in a driven optical lattice
Philipp-Immanuel Schneider, Alejandro Saenz
We propose a scheme for quantum computation in optical lattices. The qubits are encoded in the spacial wavefunction of the atoms such that spin decoherence does not influence the c…
Feshbach resonances of harmonically trapped atoms
Philipp-Immanuel Schneider, Yulian V. Vanne, Alejandro Saenz
Employing a short-range two-channel description we derive an analytic model of atoms in isotropic and anisotropic harmonic traps at a Feshbach resonance. On this basis we obtain a…
Two-channel model of photoassociation in the vicinity of a Feshbach resonance
Philipp-Immanuel Schneider, Alejandro Saenz
We derive the two-channel (TC) description of the photoassociation (PA) process in the presence of a magnetic Feshbach resonance and compare to full coupled multi-channel calculati…
