Patent office US App. 17/596523
A method of measuring an acceleration using one or more trapped BECs and at least two atomic field modes within those BECs is described. A density distribution of at least one of the one or more BECs is modified by the acceleration, which leads to a change of the field modes' time evolution. The method comprises: selecting two modes that are differently affected by the acceleration; and measuring the acceleration-induced difference; and using the measured acceleration-induced difference to infer the acceleration. Also described is a method of measuring a field gradient using one or more trapped BECs. Each of the trapped BECs has a density distribution, and at least two atomic modes within those BECs, wherein the density distributions of the one or more BECs are modified by the field, which leads to a change of the atomic modes' time evolution.
