The Physics Department presents An information theoretic approach to quantify complexity of nanoscale systems by Dr. Ilya Grigorenko

Abstract: In this study the entropy density and mutual information measures were used to identify the optimal interaction parameters between nanoparticles, which lead to the maximum geometric complexity of self-assembled nanostructures. A generalization of complexity measures at a finite temperature and for nonequilibrium systems is also presented. The developed theory can be used for efficient in silico design of new self-assembled nanostructures with a complex geometry not achievable before.

Initiative for Interstellar Studies, UK: Kevin F. Long presents Interstellar Flight: The Perspective of Theoretical Physics

The quest for the stars is an inspiring one that promises discoveries and new knowledge that has profound implications for our view of the Universe. Yet, to travel to the stars apparently requires breakthroughs in our physics and engineering knowhow. In this presentation, we examine the problem from the stand point of theoretical physics and assess the plausibility or otherwise of its fruition. We look at the many claimed reasons for why interstellar flight is perceived to not be possible and examine this thinking to elucidate an objective assessment. This includes consideration of factors such as velocity and energy requirements, particle bombardment, energetic radiation, the effects of special and general relativity in relativistic missions. We will also briefly discuss the problem of faster than light travel.

 

Light refreshments will be served.
