is pleased to announce a
Colloquium
with
Monte-Carlo
simulations of surfaces in a periodic layered structure
A new layered crystal model (LCM) is employed to carry out Monte-Carlo simulations in order to study the surface roughness in nontrival structures. The temperature dependence of the specific heat, autocorrelation time, the surface width and the surface topography are studied. Results show both roughening and preroughening phase transitions in the surface of our new model. The critical slowing down is suggested as signs of both preroughening and roughening.
