Selected topics on building simulation software for liquid crystals

Abstract:
I will review the current development phase of the so far untitled Monte Carlo molecular simulation software for a coarse-grained liquid crystal model and the included tools. Some topics addressed will be the software's support for different molecular models, future extensions, performance and what are the pros and cons of in-house development of scientific software. Also some practicalities, like development strategies, tools and libraries will be introduced briefly.

29.04. Matti Hanni
Nuclear spin relaxation due to chemical shift anisotropy in gaseous xenon

Abstract:
The nuclear spin relaxation times due to chemical shift anisotropy (CSA) of monoatomic gaseous xenon are computed from first principles using molecular dynamics simulations combined with pairwise additive approximation for the nuclear shielding tensor. The results are in excellent agreement with the experimental findings. The underlying physics is checked both for the Xe-Xe interaction potential and for the nuclear shielding tensor in the context of CSA relaxation. In the low-density xenon gas, different molecular interactions responsible for the relaxation are identified.

Title:
Multiple structural and dynamical behaviour of ionic liquids: A microscopic view.

Abstract:
Describing the liquid as well as the gas phase of complicated liquids such as ionic liquids (ILs) will continue to be a nontrivial task. [1] This is due to the fact that ionic liquids contain multiple aspects of structural and dynamical behaviour. The complete picture of ionic liquids forms by considering the sum of these aspects. In this presentation we will show the decomposition into different intermolecular forces in ionic liquids and the consequences of their unequal weights. [2-5] We will also present the ab-initio molecular dynamics simulations several ionic liquids systems and one ion pair at different temperatures and with different functional groups in order to explore the gas phase. Next, the classical simulations of [Bmim][Br] revealing the dynamical heterogeneity is discussed. [6] Finally, some ab initio simulations results of an IL mixture will be given.
