Condensed Matter Experiment
Condensed matter physics and biophysics may be described as the
search for simple, unifying
explanations for complicated phenomena observed in liquids and solids. Advances in the field lead to
universal concepts that govern the
behavior of a large number of particles. Modern research embraces
both "quantum" systems (the behavior of
electrons in solids at low temperature) and "soft" condensed
matter (liquid crystals, polymers, and
biological structure are examples).
At Princeton, experimentalists are active in superconductivity in organic metals, magnetism in spin-chain materials, the physics of nanometer-scale structures, high-temperature superconductors, ferromagnetic oxides, charge and spin density wave compounds, mesoscopic properties of subnanometer wires, quantum control of single electron spins, and the Fractional Quantized Hall Effect.
In "soft" condensed matter physics,
experimental interest includes research on sedimentation, lyotropic
liquid crystals, pattern formation in
physical and biological systems, and crystallization of
polyballs.
The work in biophysics is an extension
of the interests of the "soft" condensed matter faculty.
Experimental areas include the
understanding of molecular motors, the dynamics of DNA, the physics
of biomembranes, biopolymers and
proteins, and probes of cellular structure.
Experimentalists and theorists work
closely on many of the projects. Experimental facilities include an
x-ray spectrometer for investigating
changes on the millisecond time scale and a compact free-electron
laser for picosecond spectroscopy.
Experiments using the intense synchrotron x-ray source at the
Advanced Photon Source are also being
planned. Some of the experiments are collaborations with
