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…

Greenland sharks live for hundreds of years

While the more than 5 meter long Greenland shark is one of the world's largest sharks, it is also one of the least understood animals on our planet. The Greenland shark's general biology and way of life have been a mystery to biologists for many years. However, marine biologists at the University of Copenhagen have now deployed an epoch-making…

Jill Miwa receives a DFF Starting Grant

The Danish Council for Independent Research (DFF) has awarded a grant of 7.053.972 DKK to Associate Professor Jill Miwa from the Sapere Aude programme: DFF Starting Grant. The title of the research project is: Engineering quantum materials for next generation devices: multi-scale patterning and transport measurements by nanoscale four point probe.

The image below shows the M4 globular cluster and the position in the sky of some of the stars in which acoustic oscillations were detected. By hovering the mouse over the targets you will hear the sounds characteristic of their global oscillations. The pitch (frequencies) of the sounds have been raised by a factor 10 million to bring them into the audible range.  On the same frequency scale, the acoustic oscillations of the Sun would be so high that they would fall in the ultrasound regime.  The relative sizes of the stars studied in this work are illustrated on the right-hand panel: these are giant stars with radii from eight to sixteen times that of the Sun (which explains why their modes have such low frequencies compared to those detected in the Sun).

Earth as a 'time machine' is more efficient than calculated by Feynman

The core of the Earth is years younger than the surface. We knew that from Einsteins general theory of relativity, but a thorough recalculation shows that the original value calculated by Richard Feynman i 1962 needs correction. Instead of a few days, the difference amounts to 2,5 years. Ulrik Uggerhøj from IFA and collaborators show this in a new…
