Coherent control of rotating ion strings: towards observing spin statistics in a new regime

Presented by Hartmut Haeffner, UC Berkeley

Typically, the bosonic or fermionic nature of indistinguishable
particles is either relevant at atomic scales or when the wavefunctions
of the particles overlap. Two ions in an ion string, however, are always
separated by several micrometers making it natural to identify them am
individual particles. In order to demonstrate that the two ions may need
to be treated as the same, we plan to interfere an ion string with
itself rotated by 180 degrees. In view of this goal, we prepare ion
strings rotating with angular momenta of about 7,500 ± 30 quanta. The
fast rotation allows for coherent control of the rotational
degree-of-freedom making it possible to interfere the ion string with
its rotated version.
