condensed matter physics describe electrical, magnetical, thermal behavior in solid through solid state physics research.

electronics, material engineering, and mechanical engineering have been created now condensed matter physics has role of indicator for future engineering magnetic material and semiconductor, high temp superconductor is major research topic in condensed matter physics and it is pioneer of new material phase and major role for understanding characteristic of material. and this knowledge used for future technology.

 

 

Research Areas
Magnetic theory (Min, Byung Il)
By the Using electronic structure theory and many body theory, which is a representative methodology of condensed matter physics theory. Our laboratory research electrical, structural and topological properties of various kind solid system. By the density function theory(DFT) and Dynamical Mean Field Theory(DMFT) electric structure and analysis model hamiltonian calculation it shows magnetism, superconductivity, electron-phonon intraction, topological material property which called Transition metals with strong spin-orbit interactions and rare metal with strong correlation relationships.

Electronic structure theory laboratory (Kang, Myung Ho)
In the electronic structure theory laboratory we study atomic structure, electron band structure, and lattice vibration of the condensed matter system. First principles calculations are based on Density Functional Theory and Quantum Molecular Dynamics. The condensed matter system has main subject of surface, interface, and nanostructure. Major research topics include 1D metal atom line, 2D metal atom film, graphene, surface molecular adsorption, etc.

Nanoscale electron transport laboratory (Lee, Hyun-Woo)
Our first principal calculations are based on quantum dynamics, tight-binding model method main research topics are Ge-Sb-Te series phase transition material and 2-d graphene like material. Our study is topological phase of electronic and electronic structures and explore new material properties, fundamental physical theory, and applications based on them. recently we trying to understand amorphous-crystalline phase transition via atomic bonding and electronic structure.

Research for non perturbed electron dynamics for strong correlated material (Kim, ki-seok)
Magnetic, superconductor phase transition and high effective mass electron(up to Thousands of times) for low temp metal is really hard to understanded by perturbation method. So our laboratory trying to find non perturbated methmetical calculation method for strong correlated electron-electron interaction. The presently expected technique is a more generalized form that exists in a higher-order bending space, in which the existing Landau-Ginsberg theory, which understands the phase transition phenomenon, involves a strong interaction effect of electron. We expected that Landau-Ginsberg theory, which describes Einstein's field equations which symmetry braking related phase transitions. This mathematical structure is believed to be related to gauge-gravity duality, which is mostly studied in string theory at present.

Topological Quantum Matter Theory (Cho, Kil-young)
Quantum mechanical dynamics of electron in solid shows non classical phenomena. Representative quantum mechanical phenomena is topological phase and anyon which can be used quantum computing. Our laboratory uses quantum field theory and other computational methods to understand new topological material and anyon. Moreover our research field reach the spin liquid, Fractional Quantum State, Quantum Chaos.
