Speaker: Dr. Vincnezo Vitagliano from Keio University Abstract: External conditions have a dramatic impact on the way dynamical symmetry breaking occurs. I will review some recent (and some less recent) results of symmetry breaking in curved spacetime. Flirting with the contemporary interest toward 2D engineered material, I will then move on potential applications on geometrically deformed lattices. In a curved background, the natural expectation is that curvature works toward the restoration of an internal symmetry. I will show instead that, for topological defects, the competing action of the locally induced curvature and of boundary conditions generated by the non-trivial topology allows configurations where symmetries can be spontaneously broken close to the core.

Gravity on large scales is relatively well understood. For galaxies, planets and apples: we have Einstein’s General Relativity with which to make accurate predictions. But on small scales, where quantum mechanics becomes important, gravity is more difficult to understand, and as a result we lack precise descriptions of various natural phenomena (such as black holes).

One way to make progress in in our search for quantum gravity is to start from the large scale theory we know and love (at the ‘bottom’), and look for ways in which it may be modified and improved as we zoom in to smaller scales (going ‘up’ to a more fundamental theory).

Recent progress in ‘Effective Field Theory’ may shed some light on the connections between large and small scale physics. By exploiting certain physical properties of scattering probabilities (e.g. that they are unitary, causal and local), one can derive an infinite number of constraints which any large scale theory must satisfy in order to admit a sensible small scale completion.

In this talk, I will provide an overview of these new ‘positivity constraints’, and discuss their implications for quantum gravity.

Origami, the exquisite craft of folding paper into three-dimensional shapes, has been practiced for millennia by artists and lay people. Prof. Mahadevan will discuss some physical aspects of rigid and soft origami associated with the weak and strong deformations of thin sheets of any material. The efficient packing properties of folded matter suggest that it ought to occur naturally in physical and biological systems, and he will show that they do indeed appear on a range of scales, e.g. in drying gels, wings, leaves and even your gut as a self-organized pattern. These physical manifestations of origami suggest the question of how to design the number, location and orientation of folds to create complex shapes. Prof. Mahadevan will finish his talk with a description of attempts to solve this inverse problem, and its generalizations.

This talk will take as a starting point the Skyrmions as baryons in large- N QCD. It is further assumed that at high density, the sextic term in derivatives becomes dominant at some large density. This assumption is based on the observation that the term behaves like a perfect fluid, which is welcome for nuclear matter at large density – an environment suitable for the studies of neutron stars. With very large masses and compact radii, neutron stars become the closes known stable objects to the critical line of gravitational collapse. With some phenomenological motivation in mind, we consider the possibilities of finding exact analytic solutions to a system which is approximated by the sextic derivative term and a potential; this system is called the BPS-Skyrme model. We find a condition for when the gravitating soliton equations can be solved exactly and deduce the phenomenological implications. We furthermore find that this system has the peculiarity of not having stable black holes, meaning that the soliton cannot become scalar hair of a black hole. This is somewhat surprising, because the Skyrme soliton with a fourth-order derivative term can become stable black hole hair. We write down a class of models with higher-order derivative terms and find 2 new models that can sustain stable hair and 2 new that cannot.

Finally, we consider the problem of the classical binding energies of the Skyrmions, which are far too large compared to nuclei and explain a solution to this problem based on holography. Interestingly the solution from holography relates the baryon to the instanton of a 5-dimensional theory and the moduli of the instanton become massive modes in the Skyrmion. These modes in addition to the zero modes of the Skyrmion are expected to describe the spectra of nuclei.

Christiane Nüsslein-Volhard helped decipher the logic of the genes required to control early embryonic development. Based on her research, a plethora of transcription control genes was discovered and found to be conserved throughout evolution. In her talk she will discuss the basic mechanisms needed to establish a distinct pattern of cells during embryogenesis. She will also talk about the point of beauty in nature as well as why animals have patterns, a subject on which she has been writing a book. Her research laid the conceptual foundation for our understanding of organ formation and regeneration using the developmental control genes.
