Michael Bedzyk (Bedzyk Research Page)

Professor Bedzyk's research centers on the development of X-ray synchrotron-radiation techniques to pin-point the atomic-scale lattice location of atoms at vacuum-, gas-, fluid-, and crystal-crystalline interfaces. He is currently studying MBE-grown atomic monolayers on semiconductor and complex oxide surfaces; semiconductor and ferroelectric thin-film epitaxy; and the water/mineral interface.

Venkat Chandrasekhar (Mesoscopic Physics Research Group)
Professor Chandrasekhar's interest is in the area of mesoscopic physics, or the physics that occurs in materials at sub-micrometer length scales. His current interests include investigating the superconducting proximity effect in mesoscopic superconducting/normal-metal devices, low temperature scanning probe microscopy, complex oxides, carbon nanotubes and graphene, and the magnetic and electrical properties of nanomagnets.

Pulak Dutta (Dutta Research Page)

Professor Dutta's research is concerned with ordering and phase transitions in soft condensed materials at surfaces and interfaces. For example, his group performs in-situ X-ray scattering studies of physisorbed and chemisorbed molecular monolayers and multilayers, many of which form mesophases that are neither solid nor liquid. They also study liquids in the vicinity of solid-liquid interfaces, where these become 'solid-like'.

William Halperin (Ultra-Low Temperature Group) (NMR Laboratory)
Professor Halperin's research is in quantum fluids and solids, including unconventional superconductors, molecular transport in porous media, and ion-conducting electrolytes. His group uses nuclear magnetic resonance techniques, ultrasound, and thermodynamic methods to investigate high-temperature superconductors, heavy-fermion superconductors, and the superfluid phases of helium three. Measurements are made under extreme conditions of temperatures as low as 0.0004 K, and magnetic fields as high as 30 T.

John Ketterson
Professor Ketterson is currently engaged in high-field and ultra-low temperature studies of heavy-fermion compounds; thermoelectric and thermionic thin-film materials and devices; coherent exciton phenomena in cuprous oxide; magnetic, superconducting and nonlinear optical properties of patterned nanostructures; and photonic and superconducting devices. Ketterson is also Director of the Magnetic and Physical Properties Measurement Facility, a non-profit laboratory that provides highly accurate measurements of magnetization, magnetic susceptibility, microwave absorption, thermal transport, and other properties to researchers in physics, chemistry, biology, materials science, and geology.

Nathaniel Stern (Stern Research Page)
Professor Stern’s research is focused on the fundamental quantum interactions of photons with atoms, nano-scale structures, and magnetic materials. Specific research interests include: solid-state quantum optics, nanophotonics and cavity quantum electrodynamics, magnetization dynamics in low-dimensional structures, and spintronics.
