Improving the lifetime in optical microtraps by using elliptically polarized dipole light
Improving the lifetime in optical microtraps by using elliptically polarized dipole light
Tightly focused optical dipole traps induce vector light shifts (``fictitious magnetic fields'') which complicate their use for single-atom trapping and manipulation. The problem can be mitigated by adding a larger, real magnetic field, but this solution is not always applicable; in particular, it precludes fast switching to a field-free configuration. …
