Local probe of single phonon dynamics in warm ion crystals
Ahmed Abdelrahman, Omid Khosravani, Manuel Gessner +8
The detailed characterization of non-trivial coherence properties of composite quantum systems of increasing size is an indispensable prerequisite for scalable quantum computation,…
Strongly enhanced effects of Lorentz symmetry violation in entangled Yb+ ions
V. A. Dzuba, V. V. Flambaum, M. S. Safronova +4
Lorentz symmetry is one of the cornerstones of modern physics. However, a number of theories aiming at unifying gravity with the other fundamental interactions including string fie…
Compact FPGA-based pulse-sequencer and radio-frequency generator for experiments with trapped atoms
Thaned Pruttivarasin, Hidetoshi Katori
We present a compact FPGA-based pulse sequencer and radio-frequency (RF) generator suitable for experiments with cold trapped ions and atoms. The unit is capable of outputting a pu…
Direct spectroscopy of the SP and DP transitions and observation of micromotion modulated spectra in trapped \Ca
Thaned Pruttivarasin, Michael Ramm, Hartmut Haeffner
We present an experimental scheme to perform spectroscopy of the SP and DP transitions in \Ca. By rapidly switching lasers between bot…
Energy Transport in Trapped Ion Chains
Michael Ramm, Thaned Pruttivarasin, Hartmut Häffner
We experimentally study energy transport in chains of trapped ions. We use a pulsed excitation scheme to rapidly add energy to the local motional mode of one of the ions in the cha…
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…
