Experimental Condensed Matter Physics: (Ismet Kaya, Ahmet Oral)

The Experimental Condensed Matter Physics Group mainly focuses on the electronic and magnetic properties of nanostructures and low dimensional electronic systems under extreme physical conditions (temperatures near absolute zero and very high magnetic fields). Specimens are patterned by electron beam lithography and have features down to a few tens of nanometers. The behavior of charge carriers under these conditions represents transport regimes not only interesting for basic research but also adaptable for novel electronic device applications. Transport experiments are mostly done on graphene and GaAs based materials. Another field of study is nanoelectromechanical systems (NEMS). The research in this field is focused on development of ultrasensitive displacement sensors and their applications on the problem of detecting the mechanical quantum. These experiments involve nanofabrication and high frequency measurements at low temperatures and magnetic field. The experimental research groups also develop scientific instruments for their research. A scanning tunneling microscope (STM) that will operate at ultra high vacuum, cryogenic temperatures and magnetic field is now being built. STM is to be used as a surface science tool. It is also used to create structures with dimensions down to the atomic level and to probe their properties.

A non-contact Atomic Force Microscope(nc-AFM) operating in Ultra High Vacuum(UHV) is developed to study lateral force interactions at atomic scale. This microscope is being used to study atomic scale friction and molecular scale manipulation on Si(111) surface. A general purpose Atomic Force Microscope is also used for characterization of nanostructures. Scanning Hall Probe Microscopes(SHPM) operating at low and room temperatures are developed and used to study magnetic properties of superconductors and magnetic nanostructures. The first graphene materials have successfully been produced in the group using mechanical exfoliation. Graphene Hall sensors are being developed for SHPM applications.

Theoretical Condensed Matter Physics (Zafer Gedik, Inanc Adagideli)

The theoretical nanophysics group focuses on fundamental physics problems that arise in nanometer scale objects. Recent research interests of the group were on quantum transport in nanostructures, mesosopic physics, graphene physics, spintronics, spin Hall effect and topological insulators.

The quantum information group is working on quantum entanglement and decoherence - not only fundamental concepts of quantum mechanics but also important challenges in the construction of quantum computers.

Statistical physics (Nihat Berker)

Major research topics in statistical physics at Sabancı University include phase transitions and critical phenomena, renormalization-group theory, high-temperature superconductivity, quantum particles and spins, scale-free and small-world networks, water in nanotubes and its viscosity, and order in the presence of frozen disorder and spin glasses.
