Research interests are on theory of low-dimensional conductors and superconductors. In particular, these include studies of unconventional triplet, singlet d-wave, and LOFF superconducting order parameters in organic and high-Tc materials, unique properties of layered organic compounds in high and ultrahigh magnetic fields, superconducting phases stabilizing by a magnetic field, and properties related to changes of effective space dimensionality for some one-body and many-body phenomena in a magnetic field. These works are closely related to experiments conducting in Princeton University, Boston College, Harvard University, National High Magnetic Field Lab, Los Alamos National Lab, and some other institutions.

My research interest is using scanning probe microscopy to study interactions in nanostructures. By combining electrical transport measurements with the spatial information from scanning probe microscopy we can gain new insight into the behavior of electrons inside nanostructures. Currently we are investigating interaction effects inside carbon nanotubes using scanning tunneling microscopy. The 1D nature of nanotubes means that Coulomb interactions are very important, leading to effects such as Luttinger Liquid behavior and the Kondo effect. We are also developing new scanning probe microscopy techniques to image electron wavefunctions inside semiconductor quantum dots. This will allow the study of effects such as electron-electron interactions and coherence in these systems.

The many fascinating properties of "soft condensed matter"--e.g., liquid crystals, polymers, proteins, and living organisms--are to a large extent determined by weak intermolecular forces such as van der Waals and screened electrostatic forces. My research group is involved in the measurement and mapping of intermolecular forces at nanometer length scales using atomic force microscopy (AFM). The scientific goal is to deduce relationships between intermolecular forces and the self-organizing behavior of molecules and macromolecules at interfaces. Technological applications are also pursued; e.g, self-assembled structures are used as templates or masks for the synthesis of mesoscopic materials and molecular devices. This interdisciplinary program has established strong connections to Chemistry, Biology, Materials Science, and other engineering departments.

Dr. Mazumdar's research interests are interdisciplniary in nature and have both basic science and device oriented applied components. Primarily he is interested in developing theories of narrow band systems with strongly correlated systems, that fall outside the domain of traditional solid state physics. Examples of such systems are transition metal oxides including high temperature superconductors, organic conjugated polymers, and conducting and superconducting organic charge-transfer solids. His motivation is to understand the peculiar electric, magnetic and optical properties of these systems.

The overall research theme is the study of the physics of matter and radiation in the extreme conditions encountered near compact astrophysical objects, such as neutron stars and black holes. The main areas of current interest include the particle acceleration and radiative emission in Active Galactic Nuclei, the Galactic center, especially with regard to the massive black hole candidate Sgr A*, electron-positron plasmas near the event horizon of Cygnus X-1-like objects, and accreting neutron stars and white dwarfs in binary stellar systems.

Research interests: Theoretical AMO physics. Current interests concentrate on cavity quantum electrodynamics, matter-wave optics, and on the physics of quantum-degenerate atomic and molecular systems, including most recently Bose-Einstein condensation, ultracold polar molecules and coupled Bose-Fermi systems.
