Traps for ground-state molecules — •Bretislav Friedrich — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Faradayweg 4-6, D-14195 Berlin
The Earnshaw theorem precludes trapping of atoms or molecules via their high-field seeking states in static electric or magnetic fields. Since ground states of atoms and molecules are always high-field seeking, there has been a considerable effort to find ways of circumventing Earnshaw’s curse, by devising traps for high-field seekers made up of time-dependent electromagnetic fields. These comprise switched static fields (ac traps) or radiative fields, both resonant (MOT’s) and nonresonant (optical dipole traps).
The talk will survey the current state of the art as well as present new ideas on trapping of high-field seekers, particularly in ac traps.
