Dynamically decoupled three-body interactions with applications to interaction-based quantum metrology
K. W. Mahmud, E. Tiesinga, P. R. Johnson
We propose a stroboscopic method to dynamically decouple the effects of two-body atom-atom interactions for ultracold atoms, and realize a system dominated by elastic three-body in…
Universal and non-universal effective -body interactions for ultracold harmonically-trapped few-atom systems
X. Y. Yin, D. Blume, P. R. Johnson +1
We derive the ground-state energy for a small number of ultracold atoms in an isotropic harmonic trap using effective quantum field theory (EFT). Atoms are assumed to interact thro…
Quadrature interferometry for nonequilibrium ultracold bosons in optical lattices
Eite Tiesinga, Philip R. Johnson
We develop an interferometric technique for making time-resolved measurements of field-quadrature operators for nonequilibrium ultracold bosons in optical lattices. The technique e…
Effective renormalized multi-body interactions of harmonically confined ultracold neutral bosons
P. R. Johnson, D. Blume, X. Y. Yin +2
We calculate the renormalized effective 2-, 3-, and 4-body interactions for N neutral ultracold bosons in the ground state of an isotropic harmonic trap, assuming 2-body interactio…
Nonequilibrium Dynamics of Charged Particles in an Electromagnetic Field: Causal and Stable Dynamics from 1/c Expansion of QED
C. H. Fleming, P. R. Johnson, B. L. Hu
We derive from a microscopic Hamiltonian a set of stochastic equations of motion for a system of spinless charged particles in an electromagnetic (EM) field based on a consistent a…
Collapse and revival dynamics of superfluids of ultracold atoms in optical lattices
E. Tiesinga, P. R. Johnson
Recent experiments have shown a remarkable number of collapse-and-revival oscillations of the matter-wave coherence of ultracold atoms in optical lattices [Will et al., Nature 465,…
