Physics Review Letters Features Work From the Ketterson Lab

Work by Joe Sklenar, Seongjae Lee, and Prof. John Ketterson was recently featured on the cover of Physics Review Letters (Volume 111, Number 7). The team has recently studied the ferromagnetic resonant properties of a two-dimensional artificial quasicrystal with collaborators at the University of Kentucky Lexington as pictured here.  The tiles used are Penrose P2 kites and darts that have boundaries defined by ferromagnetic permalloy bars of width 135 nm and lengths 500, and 810 nm.

Congratulations to Joan Marler on Her New Faculty Position

Prof. Joan Marler began her faculty appointment at Clemson University this fall.  Marler was a postdoctoral fellow in Prof. Brian Odom's lab from 2009 to 2012, and returned as a visiting scholar through 2013. At Clemson, she will begin a new experimental project with trapped ultracold ions.

 Cornelius Develops Approach for Network Control

Nonlinearity is a hallmark of complex systems, but has generally been regarded as an obstacle to controlling their behavior. In a new paper published in Nature Communications, Sean Cornelius shows how nonlinear dynamics can be harnessed to control a network and drive it to desired states. The new approach can be used to identify control interventions in a range of large complex networks, from cells to power grids. Cornelius is a graduate student working with Prof. Motter.

Prof. Adilson Motter Receives the 2013 Erdős-Rényi Prize


Adilson E. Motter has received the 2013 Erdős–Rényi Prize in Network Science. Motter is being honored for his outstanding work in complex networks; the citation notes “his groundbreaking contributions to the study of synchronization phenomena and the control of cascading failures in complex networks.” The prize is given each year by the Network Science Society to one researcher in the broad field of network science under the age of 40. It consists of a cash award, a plaque and an honor lecture at the International Conference on Network Science (NetSci2013). The award ceremony took place on June 7 at the Royal Library in Copenhagen, Denmark.

Motter will donate $3,000 from his award to Northwestern undergraduate students through activities that can promote the most outstanding students in the physics and astronomy program.

MINERvA Releases New Results




            Laura Fields                               Cheryl Patrick

New results were released in May of 2013 from the MINERvA collaboration, which includes postdoc Laura Fields and graduate student Cheryl Patrick. MINERvA observes neutrino-nucleus interactions in order to better understand the behavior of protons and neutrons in the nucleus. Both Fields and Patrick work with Prof. Heidi Schellman.

Prof. Jens Koch Hosts Middle-School Physics Adventure

In May of 2013, 20 middle-school students visited Northwestern as part of the after-school Science Club run by Science in Society. They joined Prof. Jens Koch and a group of our graduate students to learn about extremely low temperatures in a "physics adventure."

Graduate student Bill Gannon told Science in Society that, “I think the thing that we hope the kids will get out of the trip is that science is not just your teacher, who you may or may not like very much, writing on the blackboard. Science is something that’s happening all the time and it’s fun and it’s not just something that’s abstract.”

Prof. Adilson Motter Featured on the Cover of Physics Today

Fifty years ago Edward Lorenz revealed deterministic predictability to be an illusion and gave birth to a field that still thrives. In an invited piece featured as the cover article of Physics Today, Prof. Adilson Motter and his colleague Prof. Campbell from Boston University discuss developments that led to the discovery of chaos and implications of this fascinating phenomenon to a broad range of areas.
