Proceedings of the National Academy of Sciences publishes work by the Bedzyk Group

The crystallization of molecules with polar and hydrophobic groups, such as ionic amphiphiles and proteins, is of paramount importance in biology and biotechnology. Research published in the Proceedings of the National Academy of Sciences by a Northwestern University collaboration demonstrated how to combine X-ray scattering and theoretical to study how crystalline order within membranes formed by coassembled cationic and anionic amphiphiles can be controlled by varying pH and molecular tail length. Their work suggests how to design bilayer membranes with specific crystalline arrangements at ambient temperature and physiologically relevant pH environments by suitable choices of molecular headgroups and tails. Changes in crystallinity are likely to affect molecular diffusion rates across membranes and may enable control over the encapsulation and release of molecules within the membrane. Moreover, pH-induced crystalline transformations are likely used by organisms to control metabolic flow in harsh environments.

Prof. Jens Koch  was awarded a CAREER grant from the National Science Foundation in September of 2011. 

His research will be on "Quantum Phases and Non-Equilibrium Dynamics of Strongly Correlated Photons".  The primary goal of the research funded by the award is to address the challenge of developing needed tools for the quantitative understanding and prediction of strongly interacting photon states and their properties.

Prof. Koch was also featured in Science in Society, where he explains some of the results and applications of quantum mechanics for Science in Society:

"The impact of quantum physics has been enormous: not only is it the prime common factor in nearly all physics Nobel Prizes awarded in the past one-hundred years, but it has also been a crucial driving force in technological advances ranging from lasers and superconductors to medical imaging like MRIs. Indeed, imagining a world in which quantum physics had never been discovered would amount to eliminating a lot of the technology we take for granted each and every day."

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.”

When tensioned, ordinary materials expand along the direction of the applied force. But a new paper published this week by Zachary G. Nicolaou and Prof. Adison E. Motter  demonstrates that not all materials have to be that way. They explored network concepts to design metamaterials exhibiting negative compressibility transitions, during which a material undergoes contraction when tensioned (or expansion when pressured). Continuous contraction of a material in the same direction of an applied tension, and in response to this tension, is inherently unstable. They achieved a conceptually similar effect, however, through destabilizations of (meta)stable equilibria of the constituents. These destabilizations give rise to a stress-induced solid-solid phase transition associated with a twisted hysteresis curve for the stress-strain relationship. The strain-driven counterpart of negative compressibility transitions is a force amplification phenomenon, where an increase in deformation induces a discontinuous increase in response force. The proposed materials are the first to exhibit longitudinal negative compressibility at zero frequency. They could be useful for the design of actuators, force amplifiers, micromechanical controls, and protective devices.

Zack, an undergraduate physics student working with Prof. Motter when the work was done, now is a first-year graduate student at Caltech.

The paper was published in Nature Materials and is available here.

A news story prepared by the NU NewsCenter is available here.

An imperative condition for the functioning of a power-grid network is that all of its power generators remain synchronized. A new study by Profs. Adilson E. Motter and Takashi Nishikawa published in Nature Physics establishes conditions under which power grids can synchronize spontaneously.  Given that most power outages involve equipment or operational errors, this is relevant both for reducing dependence on conventional control devices, thus offering an additional layer of protection, and for contributing to the development of self-healing networks that can recover from failures in real time.  The other authors of the study are Prof. Motter's former undergraduate mentee  Seth A. Myers (now a graduate student at Stanford) and Marian Anghel of LANL.

Prof. Michael Schmitt was featured in Fermilab Today on 9/27/2012. Dr. Schmitt  serves on the CMS collaboration statistics committee which validates advanced statistical methods used in particle physics measurements.

News from July 4, 2012:  The Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) presented their preliminary results on the search for the standard model (SM) Higgs boson in their data recorded up to June 2012.

CMS observes an excess of events at a mass of approximately 125 GeV with a statistical significance of five standard deviations (5 sigma) above background expectations. The probability of the background alone fluctuating up by this amount or more is about one in three million. The evidence is strongest in the two final states with the best mass resolution: first the two-photon final state and second the final state with two pairs of charged leptons (electrons or muons). We interpret this to be due to the production of a previously unobserved particle with a mass of around 125 GeV.

The Northwestern's CMS team is headed by Mayda Velasco and Michael Schmitt, and originally formed by Bruno Gobbi.

The Northwestern CMS team  is involved in several Higgs analyses. Most of them look for decays that include at least one Z boson  in the final state or di-leptons with missing energy.  Our main emphasis now will be to understand the properties of this new resonance and look for other like it.  The PhD students supervised by Velasco that are working on Higgs related analysis as part of PhD thesis work are: Nate Odell, Andrey Pozdnyakov and Brian Pollack.  Other group members also working on Higgs and Electro-Weak physics are: Anton AnastassovAndy KubikRadek OfierzinskyStoyan Stoynev and Steve Won.

Further Reading on the New Subatomic Particle Announcement from the LHC:

The Northwestern Newscenter has published an interview with Drs. Mayda Velasco and Michael Schmitt. Dr. Velasco reported that, "We are definitely entering a new era in particle physics." Read more about the discovery at the Northwestern Newscenter.

For a more in-depth look at the data from the LHC, check out Dr. Michael Schmitt's discussion of the new particle at his blog.

Right from the source: press releases are also available online from CMS, the LHC, and CERN.

In 2012 Physics World chose the discovery of a "Higgs-like Boson" by the ATLAS and CMS teams at CERN as their Top Breakthrough of the Year.  Physics World described the discovery as "the most important physics breakthrough so far in the 21st century." Congratulations to Northwestern Profs.Mayda VelascoMichael Schmitt, and Kristian Hahn for their contributions to this amazing discovery!

The Higgs discovery has been making year-end lists around the world. Prof. Mayda Velasco's work was also featured in the Puerto Rican newspaper El Nuevo Dia's list of the top 5 scientific discoveries of 2012.

From the 24th to the 29th of June, Prof. Kamal Seth hosted the June 2012 PANDA collaboration meeting. Approximately 70 physicists attended.
