Coherence lifetimes of excitations in an atomic condensate due to the thin spectrum

T. Birol, T. Dereli, Ö. E. Müstecaplıoğlu +1

We study the quantum coherence properties of a finite sized atomic condensate using a toy-model and the thin spectrum model formalism. The decoherence time for a condensate in the…

Energy protection arguments fail in the interaction picture

Kenneth R. Brown

Spin Hamiltonians with degenerate ground states are one potential system for the storage of quantum information at low temperatures. Trapped ions can be used to simulate the dynami…

Geometric phase of an atom inside an adiabatic radio frequency potential

P. Zhang, L. You

We investigate the geometric phase of an atom inside an adiabatic radio frequency (rf) potential created from a static magnetic field (B-field) and a time dependent rf field. The s…

Photoionization and Photoelectric Loading of Barium Ion Traps

A. V. Steele, L. R. Churchill, P. F. Griffin +1

Simple and effective techniques for loading barium ions into linear Paul traps are demonstrated. Two-step photoionization of neutral barium is achieved using a weak intercombinatio…

Deterministic loading of individual atoms to a high-finesse optical cavity

Kevin M. Fortier, Soo Y. Kim, Michael J. Gibbons +2

Individual laser cooled atoms are delivered on demand from a single atom magneto-optic trap to a high-finesse optical cavity using an atom conveyor. Strong coupling of the atom wit…

Entanglement between two fermionic atoms inside a cylindrical harmonic trap

B. Sun, D. L. Zhou, L. You

We investigate quantum entanglement between two (spin-1/2) fermions inside a cylindrical harmonic trap, making use of the von Neumann entropy for the reduced single particle densit…
