On genus-0 invariants of Calabi-Yau hybrid models
David Erkinger, Johanna Knapp
We compute genus zero correlators of hybrid phases of Calabi-Yau gauged linear sigma models (GLSMs), i.e. of phases that are Landau-Ginzburg orbifolds fibered over some base. These…
On genus one fibered Calabi-Yau threefolds with 5-sections
Johanna Knapp, Emanuel Scheidegger, Thorsten Schimannek
Elliptic and genus one fibered Calabi-Yau spaces play a prominent role in string theory and mathematics. In this article we discuss a class of genus one fibered Calabi-Yau threefol…
Sphere partition function of Calabi-Yau GLSMs
David Erkinger, Johanna Knapp
The sphere partition function of Calabi-Yau gauged linear sigma models (GLSMs) has been shown to compute the exact Kaehler potential of the Kaehler moduli space of a Calabi-Yau. We…
D-brane central charge and Landau-Ginzburg orbifolds
Johanna Knapp, Mauricio Romo, Emanuel Scheidegger
We propose a formula for the exact central charge of a B-type D-brane that is expected to hold in all regions of the Kahler moduli space of a Calabi-Yau. For Landau-Ginzburg orbifo…
GLSMs, joins, and nonperturbatively-realized geometries
Johanna Knapp, Eric Sharpe
In this work we give a gauged linear sigma model (GLSM) realization of pairs of homologically projective dual Calabi-Yaus that have recently been constructed in the mathematics lit…
Refined swampland distance conjecture and exotic hybrid Calabi-Yaus
David Erkinger, Johanna Knapp
We test the refined swampland distance conjecture in the Kahler moduli space of exotic one-parameter Calabi-Yaus. We focus on examples with pseudo-hybrid points. These points, whos…
