As a preliminary towards our plans to study heat transport in nanoscale systems using trapped ion chains as a 1D model, we need to measure the isotope shift in the Ca+ 729 nm electric quadrupole transition.  It turns out that … Continue reading →

After implementing a new diode laser at 866 nm and an AOM at 397 nm, Ashay Patel ’18 has successfully trapped our first mixed-species chains.  Pictured here are 40Ca+ and 44Ca+ : In both the top and bottom part of the … Continue reading →
