“Cosmological implications of the Yang-Mills vacuum and Dark Energy”  

ROMAN PASECHNIK – Lund University

 Resumen:

In my talk I will discuss important implications of the Yang-Mills (in particular, QCD) vacuum dynamics in Cosmology. Such important aspects as compensation of non-perturbative vacua at large distances, de-Sitter solutions of Einstein-Yang-Mills equations with homogeneous SU(2) condensate accounting for the vacuum polarisation, possibility for Cosmic Inflation driven by the Yang-Mills condensate and generation of Dark Energy as a gravitational correction to the QCD ground state energy will be discussed in some basic details.

Vignettes from the world of liquid crystals  

Peter Palffy-Muhoray

Liquid Crystal Institute, Kent State University – USA

Resumen:

Liquid crystals, discovered some 125 years ago, are orientationally ordered soft materials. Although they have received considerable attention – much of it due to their potential for applications in display devices – they continue to astonish, puzzle and delight. In this talk, I will describe some unusual phenomena in liquid crystalline systems which originate in orientational order. I will discuss ideas about the underlying physics, and indicate some intriguing problems that remain unsolved.
