Condensed Matter Physics studies the materials behaviors through microscopic understanding of quantum mechanical interactions among elementary objects, such as electrons and nuclei, in macroscopic systems such as solids, liquids and nanoscale devices. As the number of quantum particles in the system increases, new physical properties emerge known as collective behaviors which only manifest themselves among the collaborative quantum particles. Dr. Jong Han's research specializes on understanding the collective effects, the many-body physics, controlled by external fields.

Recent research interest in Dr. Han's group is non-equilibrium many-body physics which studies how the collective state evolves under external bias. Modern nano-electronics technology of today has realized the true non-equilibrium effects which fundamentally alter the electronic structures by driving force.

The focus topics are:

• Resistive Switching in Mott Transition Systems
• Electron Transport through Quantum Point Contacts
• Novel Devices of Dirac Materials
• Self-Organized Magnetic Patterns under Bias

Quantum mechanical models are solved by using the Keldysh diagrammatic methods to account for the non-equilibrium effects on the electron dynamics.

The 19th international conference Recent Progress in Many Body Theory (RPMBT) will be held at the Asia Pacific Center for Theoretical Physics (APCTP) in Pohang, South Korea. The conference continues the series initiated in Trieste in 1978 and is devoted to new developments in the field of many-body theories. The conference series encourages the exchange of ideas between physicists working in such diverse areas as nuclear physics, quantum chemistry, complex systems, lattice Hamiltonians, quantum fluids and condensed matter physics. The scientific sessions will start on June 25th 2017 and end on June 30th 2017.
