Quantum stability of an ion in a Paul trap revisited
A. Hashemloo, C. M. Dion
We study the quantum stability of the dynamics of ions in a Paul trap. We revisit the results of Wang et al. [Phys. Rev. A 52, 1419 (1995)], which showed that quantum trajectories…
Wave-packet dynamics of an atomic ion in a Paul trap: approximations and stability
A. Hashemloo, C. M. Dion, G. Rahali
Using numerical simulations of the time-dependent Schrödinger equation, we study the full quantum dynamics of the motion of an atomic ion in a linear Paul trap. Such a trap is base…
Directed transport with real-time steering and drifts along pre-designed paths using a Brownian motor
H. Hagman, M. Zelan, C. M. Dion +1
We have realized real-time steering of the directed transport in a Brownian motor based on cold atoms in optical lattices, and demonstrate drifts along pre-designed paths. The tran…
Fluctuation-induced drift in a gravitationally tilted optical lattice
M. Zelan, H. Hagman, K. Karlsson +2
Experimental and theoretical studies are made of Brownian particles trapped in a periodic potential, which is very slightly tilted due to gravity. In the presence of fluctuations,…
Simulations of Sisyphus cooling including multiple excited states
F. Svensson, S. Jonsell, C. M. Dion
We extend the theory for laser cooling in a near-resonant optical lattice to include multiple excited hyperfine states. Simulations are performed treating the external degrees of f…
A nonadiabatic semi-classical method for dynamics of atoms in optical lattices
S. Jonsell, C. M. Dion, M. Nylén +3
We develop a semi-classical method to simulate the motion of atoms in a dissipative optical lattice. Our method treats the internal states of the atom quantum mechanically, includi…
