    • F-theory on quotient threefolds with (2,0) discrete superconformal matter 

      Anderson, Lara B.; Grassi, Antonella; Gray, James; Oehlmann, Paul-Konstantin (Springer, 2018-06-20)
      We explore 6-dimensional compactifications of F-theory exhibiting (2, 0) superconformal theories coupled to gravity that include discretely charged superconformal matter. Beginning with F-theory geometries with Abelian ...

      Polarized microscope observation of ferroelastic domains in a SrBi2Ta2O9 (SBT) single crystal reveals the presence of domains up to T(c1)similar or equal to770 K, which supports the ferroelasticity and Amam symmetry of the ...
    • Fibrations in CICY threefolds

      Thies, M.; Schmittmann, B. (American Physical Society, 2000-01)
      With the help of Monte Carlo simulations and a mean-field theory, we investigate the ordered steady-state structures resulting from the motion of a single vacancy on a periodic lattice which is filled with two species of ...
    • Field-theoretic methods 

      Täuber, Uwe C.
      Many complex systems are characterized by intriguing spatio-temporal structures. Their mathematical description relies on the analysis of appropriate correlation functions. Functional integral techniques provide a unifying ...
