Oral presentation

An alternative class of the Lagrangian called the multiplicative form is successfully derived. This new Lagrangian can be considered as a one parameter, namely the speed of light, extended class from the standard additive form of the Lagrangian since both yield the same Newtonian equation.

Oral presentation

Kinetic Monte Carlo (KMC) is an algorithm which finds transitions between states during an evolution of a system out of equilibrium according to the prescribed transition rate probabilities. One Major caveat with the original KMC is no attention that is given to how the system interacts with the environment. In particular, it is not known how the transition rate probability matrix plays a role...
