UGA researchers use single molecule of DNA to create world’s smallest diode
UGA researchers single molecule DNA smallest diode
2016/4/13
Researchers at the University of Georgia and at Ben-Gurion University in Israel have demonstrated for the first time that nanoscale electronic components can be made from single DNA molecules. Their s...

2015/4/13
A proposed pathway to construct quantum computers may be the outcome of research by a University of Oklahoma physics team that has created a new molecule based on the interaction between a highly-exci...
Incoherent dynamics of vibrating single-molecule transistors
Nanometer quantum island single electron transistor model dynamics
2014/12/20
We study the tunneling conductance of nanoscale quantum “shuttles” in connection with a recent experiment [H. Park et al., Nature 407, 57 (2000)] in which a vibrating C60 molecule was apparently funct...
Spin current and polarization reversal through a single-molecule magnet with ferromagnetic electrodes
Spin current polarization reversal single-molecule magnet ferromagnetic electrodes
2012/2/27
We theoretically study the spin-polarized transport through a single-molecule magnet, which is weakly coupled to ferromagnetic leads, by means of the rate-equation approach. We consider both the ferro...
Total angular momentum representation for atom-molecule collisions in electric fields
Total angular momentum representation atom-molecule collisions electric fields
2012/2/28
It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed coordinated frame, le...
Interstitial BiO molecule as a center of broadband IR luminescence in bismuth-doped silica glass
Interstitial BiO molecule broadband IR luminescence bismuth-doped silica glass
2011/8/18
Abstract: IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in interstitial Bi...
Lognormal Distribution of Single Molecule Fluorescence Bursts in Micro/Nano-Fluidic Channels
Lognormal Distribution Single Molecule Fluorescence Burst Micro/Nano-Fluidic Channels
2011/8/5
Abstract: The width and shape of photon burst histograms pose significant limitations to the identification of single molecules in micro/nano-fluidic channels, and the nature of these histograms is no...

Modifying molecule-surface ultrashort laser pulses Quantum Physics
2011/8/2
Abstract: In recent years it became possible to align molecules in free space using ultrashort laser pulses. Here we explore two schemes for controlling molecule-surface scattering process, which are ...
The self-assembly of artificial 3D nanostructures on a surface has been achieved for the first time, claims a team of researchers in the UK. Until now, such assembly was only possible in 2D and the sc...
