Poster Dec. 2008

The Leung Center for Cosmology and Particle Astrophysics (LeCosPA) of the National Taiwan University (NTU) is organizing a Mini-Workshop on Dark Energy and Vacuum Structure, to be held in Taipei, Taiwan on December 2 to 4, 2008. A guided Taipei City Tour will be provided for participants from abroad, free of charge, on Friday, 8:30-16:00, Dec. 5.

The expansion dynamics of the Universe is dominated in the present era by dark energy, which makes up roughly 75% of its total energy content. Still, it takes the size of the Universe to make visible the tiny energy density of (2.4meV)4. Einstein's cosmological constant Λ is the observationally favored candidate for dark energy, implying the presence of a non-material gravitating vacuum structure. In this sense the "ether gravitates". However, there are as to date no tangible models for how this dark energy would come about.

An important question is, if the magnitude of dark energy introduces a new physical scale or if it arises from some yet to be discovered mechanism of known physics, for example from certain deformations of the electroweak and/or the QCD vacuum structure. Such a deformation could be due to, e.g.,

Other models based on deviations from known physics are also of interest in order to obtain an understanding of Λ, and future observations can as such act as high precision tests of new physics. A related issue is whether laboratory experiments could shed any light on this profound problem or not, and if so in what form. Thus an important objective will be the search for novel experimental directions that would allow for studies of dark energy, for instance the possible use of strong fields generated by intense lasers.

The workshop aims to create a forum for an open and frank exchange of ideas center around the topic of dark energy and its relation to vacuum structure. In order to maximize the interaction, we have to limit the number of participants. The attendance of this mini-workshop is therefore by invitation only. If you are interested in attending this workshop, please communicate with us ASAP before November 7, 2008.
