A metastable state in with lifetime greater than 10 minutes
Hassan Farhat, William Liu, Wesley C. Campbell
We find through direct, time-domain measurement of trapped ions that the excited state has a collision-free lifetime of 17.8(6) min, long enoug…
Sub-hertz optical transitions in excited Yb
Patrick McMillin, Hassan Farhat, William Liu +1
We present the observation of three semi-forbidden transitions in singly-ionized ytterbium from the metastable state. Owing to the long lifetimes of both t…
Angular Geometry of Atomic Multipole Transitions
Wesley C. Campbell
A simple way to calculate Rabi frequencies is outlined for interactions of atomic or nuclear multipole moments with laser fields that focuses on their relative geometry. The result…
Direct frequency comb laser cooling and trapping
A. M. Jayich, X. Long, W. C. Campbell
Continuous wave (CW) lasers are the enabling technology for producing ultracold atoms and molecules through laser cooling and trapping. The resulting pristine samples of slow movin…
Quantum Control of Qubits and Atomic Motion Using Ultrafast Laser Pulses
J. Mizrahi, B. Neyenhuis, K. Johnson +4
Pulsed lasers offer significant advantages over CW lasers in the coherent control of qubits. Here we review the theoretical and experimental aspects of controlling the internal and…
