May 30, 2024 · Ziqi Liu leads us in a further exploration of Kähler geometry.We begin this talk with some equivalent definitions of Calabi-Yau manifolds; we focus then on C...
6 days ago · Then one can deform this model and still obtain a physical model for string theory. This is an example of a Landau-Ginzburg model. Mirror symmetry has been established for Landau-Ginzburg models in a few cases, and it has been shown to be powerful in the study of classical higher-dimensional shapes such as Calabi-Yau manifolds.
May 26, 2024 · String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a patch of space, the theory says, and you won’t see a ...
May 17, 2024 · The KK-compactification of D=10 super Yang-Mills theory all the way to the point yields a theory whose fields are simply elements of the gauge Lie algebra 𝔤 \mathfrak {g}, hence matrices for a matrix Lie algebra. This physics is called the IKKT matrix model.
May 15, 2024 · The interaction terms. The unrestricted configuration space of string field theory is the subcomplex of the BRST complex of the closed ( super -) string, regarded as a ℕ - graded vector space with respect to the ghost number grading, on those elements Ψ that satisfy. We shall write 𝔤 for this graded vector space.
May 22, 2024 · A p-form global symmetry in a quantum field theory is a global symmetry for which the charged operators are p-dimensional objects. For instance, Wilson line operators may be charged under a 1-form global symmetry, while local operators may be charged under a 0-form global symmetry. Such a symmetry is labeled by a group G, and when Gis continuous,

May 29, 2024 · The theory of inflation is the leading candidate for the very early universe physics responsible for both the large-scale homogeneities and small-scale inhomogeneities of our universe, through a period of an almost-de Sitter phase lasting approximately sixty efolds. Despite this, there remains much uncertainty as to the right microphysics of ...
