Ultracold atomic quantum gases far from equilibrium
We calculate the time evolution of a far-from-equilibrium initial state of a non-relativistic ultracold Bose gas in one spatial dimension. The non-perturbative approximation scheme is based on a systematic expansion of the two-particle irreducible effective action in powers of the inverse number of field components. This yields dynamic equations which contain direct scattering, memory and off-s...
متن کاملImplementing quantum electrodynamics with ultracold atomic systems
Wediscuss the experimental engineering ofmodel systems for the description of quantum electrodynamics (QED) in one spatial dimension via amixture of bosonic Na and fermionic Li atoms. The local gauge symmetry is realized in an optical superlattice, using heteronuclear boson– fermion spin-changing interactions which preserve the total spin in every local collision.We consider a large number of b...

متن کاملQuantum Dynamics of Ultracold Bose Polarons.
We analyze the dynamics of Bose polarons in the vicinity of a Feshbach resonance between the impurity and host atoms. We compute the radio-frequency absorption spectra for the case when the initial state of the impurity is noninteracting and the final state is strongly interacting with the host atoms. We compare results of different theoretical approaches including a single excitation expansion...
متن کاملQuantum dynamics of ultracold Na+ Na2 collisions.
Ultracold collisions between spin-polarized Na atoms and vibrationally excited Na2 molecules are investigated theoretically, using a reactive scattering formalism (including atom exchange). Calculations are carried out on both pairwise additive and nonadditive potential energy surfaces for the quartet electronic state. The Wigner threshold laws are followed for energies below 10(-5) K. Vibratio...
