A new method of surface dynamics = 표면 동력학의 새로운 방법

다국어 초록 (Multilingual Abstract)

We developed a new method of studying surface dynamics of metal surfaces by
combining the analytic and simulational methods. In this formalism, the vibrational motion of bulk atoms are considered to be harmonic using a central force model, however, that of surface atoms is considered to be anharmonic in order to explain the surface structural change. We show that the dynamical structure factor can be expressed as a continued fraction and its expansion parameters are equilibrium thermodynamic averages, which can be evaluated through Monte Carlo simulation. Therefore, we conclude that the static behaviors and surface dynamics which are anhamonic and critical can be studied more systematically at the same time.
