JILA physicists have extended the capability of their powerful laser "combing" technique to identify the structures of large, complex molecules of the sort found in explosives, pharmaceuticals, fuels and the gases around stars.

In a recent Phys. Rev. E article, David Nelson, together with Ariel Amir (SEAS; formerly Harvard Physics Junior Fellow) and Naomichi Hatano (UTokyo), analyzed the eigenvalues and eigenvectors of certain asymmetric tridiagonal matrices. The authors found a rich and complex behavior in the distribution of eigenvalues and the localization properties of eigenvectors. This has implications that can help understand features of the dynamics of neural networks, as well as neural development in organisms.

As population growth continues to outpace development of water infrastructure in many countries, desalination (the removal of salts from seawater) at high energy efficiency will likely become a vital source of fresh water. Due to its atomic thinness combined with its mechanical strength, porous graphene may be particularly well-suited for electrodialysis desalination, in which ions are removed under an electric field via ion-selective pores.

Graduate students Michael Coughlin and Christopher Frye won the 2016 Maurice and Gertrude Goldhaber Prize (for experimental and theoretical physics, respectively).
The prize is awarded annually by the department to its most outstanding current PhD students after they pass their qualifying exams, based on their accomplishments, creativity, and innovative approaches to research, as determined by a vote of the faculty.
