N. Peter Armitage has been at Johns Hopkins University since 2006. He received his B.S. in Physics from Rutgers University in 1994 and his Ph.D. from Stanford University in 2002. He is a physicist whose research centers on material systems which exhibit coherent quantum effects at low temperatures, like superconductors and "quantum" magnetism. Dr. Armitage's principal scientific interest is understanding how is it that large ensembles of strongly interacting, but fundamentally simple particles like electrons in solids act collectively to exhibit complex emergent quantum phenomena. He is exploiting (and developing) recent technical breakthroughs using very low frequency microwave and THz range radiation to probe these systems at their natural frequency scales. The material systems of interest require novel measurement techniques as their relevant frequencies typically fall between the range of usual optical and electronic methods.
He has been the recipient of a DARPA Young Faculty Award, an NSF Career Award, a Sloan Research Fellowship, was a three time Kavli Frontiers Fellow, the Spicer Award from the Stanford Synchrotron Radiation Laboratory, the McMillan Award from the University of Illinois and 2016 Genzel Prize. He was also the co-chair of the 2014 Gordon Research Conference in Correlated Electron Systems.
The Armitage lab at Johns Hopkins University uses various 'optical' techniques to investigate a variety of complex condensed matter systems. The main interest of the group is exotic electronic states of matter at low temperatures, including exotic superconductors, novel magnetic states, electronic glasses, and materials in proximity to quantum critical points. Other areas of interest are nanostructures, biological physics, and aspects of physical chemistry and quantum optics.
We are developing a number of low-energy optical spectroscopies in the so-called 'Terahertz gap' - the experimentally difficult frequency region above that attainable with electronics, but below that accessible with optics (photonics). This frequency range is host to many phenomena in condensed matter systems and is a frontier in 'optical' and condensed matter research. Among other apparatuses, we are implementing a novel time-domain THz spectrometer, which is one of the emerging tools for condensed matter physicists in obtaining spectroscopic information in this technically challenging frequency range. A new microwave `Corbino' broadband spectrometer has also been developed.
We are members of the Institute for Quantum Matter(IQM). IQM is a collaboration between Johns Hopkins University and Princeton University funded by the DOE, which seeks to expose and understand materials dominated by quantum coherence and correlations. IQM combines chemical synthesis, advanced spectroscopy, and theoretical analysis for new fundamental understanding of interacting many-body systems.
The Armitage lab is located in the Bloomberg Center for Physics and Astronomy at Johns Hopkins University. The address is 3701 San Martin Dr, Baltimore, Maryland, 21218. The best way to find Bloomberg is to avoid the main campus on Charles St, and instead, travel on San Martin Drive. Bloomberg is directly across the street from the Space Telescope Science Institute. Once you've located Bloomberg, head straight down to the 0th floor and look for lab 033 to find us.
