| Exploring the Neutron Drip Line and Beyond |
| Speaker: | Prof. Takashi Nakamura (Department of Physics, Tokyo Institute of Technology) |
| Abstract: | How many more neutrons can be added to an atomic nucleus? Indeed, there exists a neutron-rich limit, called "neutron drip line", where any neutrons cannot be added any longer to form
a bound nucleus. For instance, 24O(Z=8,N=16) is the most neutron-rich oxygen isotope,
while that for Z=9 (Florine) is 31F(Z=9,N=22), so both these nuclei are on the neutron drip line. The location of the neutron drip line on the nuclear chart is, however, yet unknown above neon (Z=10) isotopes, and thus this provides challenges for modern nuclear structure theories. We also ask ourselves how atomic nuclei behave near and beyond the neutron drip line.
With these questions in mind, I present recent experimental studies on exotic nuclei
near/beyond the neutron drip line using... [for full abstract please visit: https://indico.smi.oeaw.ac.at/event/219/] |

| Calabi-Yau Volumes and Reflexive Polytopes |
| Speaker: | Yang-Hui He (CITY Univ. of London) |
| Abstract: | im Rahmen des Seminars für Mathematische Physik: We study various geometrical quantities for Calabi-Yau varieties realized as cones over Gorenstein Fano varieties, obtained as toric varieties from reflexive polytopes in various dimensions. We concentrate on reflexive polytopes up to dimension 4 and calculate the minimized volume of the Sasaki-Einstein base of the corresponding Calabi-Yau cone.
By doing so we conjecture new bounds for the Sasaki-Einstein volume with respect to many topological quantities of the corresponding toric varieties. We give interpretations
about these volume bounds in the context of associated field theories via the AdS/CFT correspondence. Based on joint work with R.-K. Seong and S.-T. Yau.
