Low Power Atom Chip

Atom chips are an example of one of the early attempts to make the production of cold atoms, in particular quantum gases easier, less power consuming and better controlled, with a lot of suc-cesses and a high state-of-the-art. However, today’s atom chips typically still need external coils with relatively high power consumption and the non-transparent surface of the chip limits manipulation and detection schemes. So far there are only few attempts for precision measurement using atom chips, e.g. for atom clocks  and only one demonstration has been made with a transparent chip so far. iSense aims at the further completion of the atom chip revolution and realize novel ideas by designing low-power atom chips without external coils in particular for sensor applications, using transparent conductor technology.

 

Research progress in the 1st year

A first generation stand-alone atom chip has been demonstrated to trap atoms in a magneto-optical trap with a power consumption below 5W, although a current requirement of 100 A. A second generation chip has been designed with a current requirement of 20 A and will be fabricated within the next months.
