Accurate and fast quantum simulation to predict chemistry. Quantum mechanical simulation is the most accurate tool available for predicting and understanding chemical reactions. Traditional techniques for performing quantum mechanical simulations of molecular collisions and reactions cannot be applied to more than five or six atoms, meaning that it is not possible to study most chemical reactions in full detail. In this project a new technique for performing these accurate simulations, recently ....Accurate and fast quantum simulation to predict chemistry. Quantum mechanical simulation is the most accurate tool available for predicting and understanding chemical reactions. Traditional techniques for performing quantum mechanical simulations of molecular collisions and reactions cannot be applied to more than five or six atoms, meaning that it is not possible to study most chemical reactions in full detail. In this project a new technique for performing these accurate simulations, recently invented at the Australian National University and allowing the study of much larger systems, will be developed and applied to important outstanding problems in chemical dynamics, ranging from roaming in formaldehyde to atom migration in proteins.Read moreRead less

Nonlinear models dominate the frontline of modern theoretical and applied mathematics. This project concerns contemporary variational problems with analysis linked strongly to the Monge-Ampere equation, which is a fully nonlinear partial differential equation. Its study in recent years has generated complex and deep theoretical issues along with a diverse range of applications. The proposal is divided into two themes, affine maximal surfaces (involving fourth order partial differential equations of Monge-Ampere type) and optimal transportation (where Monge-Ampere theory has been applied successfully in recent years). Each of these builds upon major recent research breakthroughs of the proposers.Read moreRead less
