▪ 연구방법
Our research group searches for various novel features in disordered quantum matter under out-of-equilibrium conditions. Associated theories and methods, if necessary, will be learned as your re-search moves forward. The structure of the way our theory research works can be roughly sketched as follows:(i) Spot an interesting problem to investigate from various sources (seminar talks, research papers, news media, etc.). While the concept of ‘interesting’ is subjective, if you can draw your colleagues’ attention to the problem, then it may be interesting enough. (ii) Model the problem. Construct a minimal model that can capture the essential physics that you are pursuing. This step is crucial. It is highly related to the successful completion of a project. (iii) Solve the model and find relevant physical quantities of your sought-after problem. In our research group, we employ numerical and analytic approaches together. A seemingly simple model in physics often doesn’t yield a simple analytic solution. Numerical approaches are often limited by computing resources. The two (or more, if available) approaches shall be joined and provide consistent results. Our group typically enjoy but not limited to the following techniques:· Condensed matter field theory· Numerical analysis, Computational methods· Non-equilibrium Green's function approach(iv) Propose feasible experiments which can verify your ‘theory’. No matter how bizarre your theory is, condensed matter systems will find you a platform of your theoretical predictions and it will unfold more of unexpected phenomena.
