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…

Trapped ions in optical lattices for probing oscillator chain models

Thaned Pruttivarasin, Michael Ramm, Ishan Talukdar +2

We show that a chain of trapped ions embedded in microtraps generated by an optical lattice can be used to study oscillator models related to dry friction and energy transport. Num…

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…
