Scientists Trying to Manipulate, Control Radiation of Single Molecules in Very Short Time Scale

Tehran, Iran | Posted on June 2nd, 2014

Results of the research can be used in designing new devices to detect quantum systems.

The researchers studied a method that enables the manipulation of quantum properties of single molecules. Their objective was to study controllable changes in molecular energy level width at a very short time scale. By using the results of this research and in addition to manipulating the properties, the molecule position can be detected without the need for accurate and expensive devices depending on how energy level width changes with time.

According to Dr. Nafiseh Zavvaria who is graduated from Shahid Beheshti University in the field of atomic physics, energy level width in quantum systems depends on both their wave function and the environment. Although many studies have so far been carried out on the changes in energy level width by using various structures, specially plasmonic nanostructures, none of them have provided time controlling ability in the width. A metallic nano-antenna on a specific substrate has been used in the calculation to achieve this capability. The designed substrate includes a few layers, the most important of which is a microfilm made of gallium.

Results showed that considering the position of the molecule within the nanostructure, changes are different in energy level width, and the amount of difference can be used in determination of the molecule position. The nano-antenna is used to increase the changes in molecular energy level width so the detection of the changes in time takes place more easily.

Results of the research have been published in Laser Physics Letters, vol. 11, issue 4, February 2014, pp. 1-7.
