Implications of surface noise for the motional coherence of trapped ions
I. Talukdar, D. J. Gorman, N. Daniilidis +5
Electric noise from metallic surfaces is a major obstacle towards quantum applications with trapped ions due to motional heating of the ions. Here, we discuss how the same noise so…
Probing surface electric field noise with a single ion
N. Daniilidis, S. Gerber, G. Bolloten +5
We report room-temperature electric field noise measurements combined with in-situ surface characterization and cleaning of a microfabricated ion trap. We used a single-ion electri…
Precision Measurement Method for Branching Fractions of Excited P1/2 States Applied to 40Ca+
Michael Ramm, Thaned Pruttivarasin, Mark Kokish +2
We present a method for measuring branching fractions for the decay of atomic energy levels to lower-lying states based on time-resolved recording of the atom's fluoresce…
Sub-Fourier characteristics of a -kicked rotor resonance
I. Talukdar, R. Shrestha, G. S. Summy
We experimentally investigate the sub-Fourier behavior of a -kicked rotor resonance by performing a measurement of the fidelity or overlap of a Bose-Einstein condensate (BEC) ex…
Resonances of the Quantum -Kicked Accelerator
V. Ramareddy, G. Behinaein, I. Talukdar +2
We report the observation of high order resonances of the quantum -kicked accelerator using a BEC kicked by a standing wave of light. The signature of these resonances is the ex…
Experimental Realization of Quantum-Resonance Ratchets
I. Dana, V. Ramareddy, I. Talukdar +1
Quantum-resonance ratchets associated with the periodically kicked particle are experimentally realized for the first time. This is achieved by using a Bose-Einstein condensate exp…
