Institute for Quantum Matter,
a collaboration between Johns Hopkins and Princeton Universities,
combines materials synthesis, advanced spectroscopy, and
theory to uncover new materials functionality based on quantum correlations.
The Principal Investigators are C. Broholm (Director), N. P. Armitage,
Cava (Princeton), T. McQueen, O. Tchernyshyov, and Z. Tesanovic.
Areas of interest include frustrated quantum magnetism, quantum criticality,
quantum impurities, correlated superconductivity, and the
interplay between these phenomena. IQM is currently soliciting applications
for postdoctoral and staff
Successful candidates will participate in coordinated research at the interface between theoretical and experimental condensed matter physics,
chemistry, and materials science.

Our group maintains active experimental and theoretical
research programs at the forefront of both "hard" and "soft"
condensed matter physics. Examples
of the former are quantum magnets studied by neutron scattering
techniques (Broholm, Reich), experiment and theory of magnetic
nanostructures and quantum nanowires (Chien, Markovic,
Reich, Tchernyshyov, Walker),
broadband microwave and terahertz spectroscopy of correlated electron systems
physics and chemistry of new materials
and theory of
correlated magnets, rare-earth metals and superconductors
The latter includes dynamical studies of conformational transition in proteins
x-ray and neutron scattering studies of glasses and out-of-equilibrium
complex fluids (Leheny), biological applications of nanostructures
(Markovic, Reich) and analytic and computer-aided theory of
non-equilibrium processes, adhesion and friction
JHU is the home of Materials Research Science and Engineering Center
(MRSEC) on magnetic nanostructures and magnetoelectronics, a large NSF funded center for
interdisciplinary research in nanotechnology, and the newly-formed
DOE supported Johns Hopkins-Princeton Institute for Quantum Matter
Nearby NIST, a large
government research lab and a premier US
facility for neutron scattering research, benefits from close
involvement of several JHU groups, most notably through a multi-million
dollar Multi Axis Crystal Spectrometer
conceived and built at JHU.
Our group is committed to interdisciplinary research in both
hard and soft physical sciences and takes
advantage of JHU's preeminent status in nanomaterials,
biophysical and biomedical sciences and bioengineering through numerous
interactions and collaborations with
Departments of Materials Science
and Engineering, Biophysics,
Biomolecular Engineering, notably under the auspices of the JHU
Institute for NanoBioTechnology (INBT).
In addition, the JHU Applied Physics Laboratory has a large program in applied condensed matter
sciences and is a leading center in quantum optics and
optical quantum computing. Finally, the JHU's central
location in the
Baltimore-Washington metro area
places it at the heart
of one of the largest condensed matter science communities in the
Johns Hopkins scientists are at the forefront of the exciting new field of
iron-based high temperature superconductors (see recent article in
USA Today on
Top Ten Science Developments in 2009).
These new materials are different
from old copper-oxide-based HTS and offer a possible new pathway to room
temperature supercoonductivity and its many applications. See their paper in
and the JHU
The JHU led Partnership for Research and Education in Materials
(PREM) is chosen as a new NSF funded collaboration aiming to
enhance minority participation in
research and education in nanomaterials.
The PREM at Johns Hopkins, Howard University and Prince George's
Community College will receive $2.75 million over five years
and is one of six new such partnerships receiving a
total of $15.4 million from the National Science Foundation.
The others are California State and
Princeton universities; Jackson State University and the University of California, Santa Barbara; Norfolk State and Cornell universities; Tuskegee and Cornell universities; and the University of New Mexico and Harvard University. The full story is

Events & Activities
The main group activities include a weekly condensed matter physics
where latest research developements are
discussed with a steady stream of visitors
from around the world. In addition, individual research groups hold
their own regular schedule of meetings, often in collaboration with
other JHU departments. Every year or two an especially distinguished
condensed matter physicist spends three days at JHU as a
Brickwedde Lecturer in Physics.
