New solar cell technlogy based on a toy

Solar cells are expensive and difficult to mount and maintain, putting researcers always on the alert for new ways of producing them. A team of researchers based at the Department of Physics and Astronomy and iNano at Aarhus University went to the toyshop and found something that may cause a major break-through.

Breaking up carbon

Breaking up is hard to do, no matter whom or when. Take for example the case of a carbon nucleus splitting into three nuclei of helium. Until recently no-one knew if such a breakup happened suddenly or in a longer sequence of successive fragmentations. Now we know.

New postdoc: Andreas Næsby

Andreas Naesby joined the group of Aurelien Dantan as a postdoctoral researcher on the 15th of August. He will work on developing new electro-opto-mechanical systems where vibrations of micromechanical drums interact both with optical light fields and electrical fields.

The cold gas is trapped in the oblong (blue) 'bucket' to the left by means of a magnetic field setup not shown in this drawing. Laser light is beamed through the gas, causing the polarization of the light to rotate. The light is transmittet through a filter enabling only the rotated part of the light to reach a CCD camera, recording a large number of images of the light. This is called Faraday imaging. Each picture is analyzed on-line in an integrated circuit, the FPGA (Field Programmable Gate Array). Via the RF unit, the FPGA orders the magnetic trap to open, letting a few atoms out of the trap, and a new series of images are recorded, verifying the stabilization. The photo diode PD ensures that the intensity of the laser is unchanged during the experiment, ensuring the best possible statistics on the number of atoms.

Countable cold clouds of atoms

Put some cold atoms in a closed magnetic 'bucket' - count how many you have, throw away the excess - and do it again and again with the same number of atoms. At IFA Jan Arlt's research group has developed a new and promising technique to assure that a known number of atoms can be reproduced time after time i cold atomic clouds. The results have…
