Overcoming the Decoherence Caused by Three-Body Collision in One-dimensional Single-mode Atomic Waveguide

Abstract

We investigate the decoherence dynamics caused by three-body interaction in one-dimensional sinlge-mode atomic waveguide. By using proper Feshbach resonance to modulate the relative interaction strength, the coherence can be recovered.

Quantum decoherence in a hybrid atom-optical system of a one-dimensional coupled-resonator waveguide and an atom

Jing Lu, Lan Zhou, H. C. Fu +1 more

Decoherence for a one-dimensional coupled-resonator waveguide with a two-level system inside one of the resonators, induced by their interaction with corresponding environments, is investigated. Each environment is modeled as a continuum of harmonic oscillators. By finding the eigenstates of the hybrid system, which is the dressed state of the hybrid system, we calculate the lifetime of one excitation, which characterizes the existence of quantum coherence in such hybrid systems and the basic quantum nature.

Pure confinement-induced trimer in one-dimensional atomic waveguides

Ludovic Pricoupenko

Shallow trimers composed of three bosonic atoms in one-dimensional harmonic waveguides are studied in the vicinity of a Feshbach resonance. It is shown that for arbitrarily large values of the one-dimensional scattering length, an excited trimer branch exists in coexistence with the dimer and the trimer of the Lieb-Liniger model.

Atom Interferometry with a Weakly Interacting Bose Einstein Condensate

M. Fattori, Chiara D’Errico, G. Roati +5 more

We demonstrate trapped atom interferometry with a weakly interacting Bose Einstein condensate. Atomic scattering length is tuned almost to zero by means of a broad magnetic Feshbach resonance and interaction induced decoherence results strongly suppressed.

One-Dimensional Bose Chemistry: Effects of Nonintegrability

Vladimir Yurovsky, A. Ben‐Reuven, Maxim Olshanii

Three-body collisions of ultracold identical Bose atoms under tight cylindrical confinement are analyzed. A Feshbach resonance in two-body collisions is described by a two-channel zero-range interaction. Elimination of the closed channel in the three-body problem reduces the interaction to a one-channel zero-range one with an energy-dependent strength. The related integrable Lieb-Liniger-McGuire (LLMG) model, with an energy-independent strength, forbids all chemical processes, such as three-atom association and diatom dissociation, as well as reflection in atom-diatom collisions. The resonant case is analyzed by a numerical solution of the Faddeev equations. The results demonstrate that as the internal symmetry of the LLMG model is lifted, reflection and chemical reactions become allowed and may be observed in experiments.

Intrinsic decoherence in atomic diffraction with a standing light wave

Stefano Mancini, Rodolfo Bonifacio

We study the effects of time uncertainty in the interaction of atoms with a standing light wave. We discuss its physical origin and the possibility to observe intrinsic decoherence effects by measuring the atomic momentum distribution.

Properties of quasi-one-dimensional molecules with Feshbach-resonance interaction

Vladimir Yurovsky

Bound states and collisions of atoms with two-channel two-body interactions in harmonic waveguides are analyzed. The closed-channel contributions to two-atom bound states become dominant in the case of a weak resonance. At low energies and values of the nonresonant scattering length the problem can be approximated by a one-dimensional resonant model. The three-body problem becomes nonintegrable and the properties of triatomic molecules become different from those predicted by the integrable Lieb-Liniger-McGuire model.
