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
