Lab Description
Physical and chemical properties of materials are governed by electromagnetic interaction between charged species. Particles heavier than few-nucleon can be easily described by classical equations of motion. However, electrons require a special treatment because of their uncertainty in exhibiting quantitative properties. The most prevailing theory in last one century has been the quantum mechanics where distribution of electrons is probabilistically given by a squared wave function. Once we know the distribution of electrons or the initial wave function, all the microscopic behavior later on, in principle, can be predicted by using the Schrodinger equation of motion and quantum statistical mechanics. But, practically, it is still challenging to describe system of many particles interacting among themselves, namely the complex system, where only qualitative behavior has been known with simplified models. For reliable and quantitative description of physical and chemical properties of materials, we need high-performance computation power together with numerical approaches solving quantum mechanics. By using various state-of-the-art numerical methods, our group is mainly oriented to studying novel phenomena of nanoscale systems, related to next-generation electronic/spintronic/optical devices and high-efficient energy/environment catalysts. In addition, we develop a numerical code to describe strongly correlated systems in non-equilibrium steady-state situation.
