A single point as a Calabi-Yau zerofold

TL;DR

This paper explores a non-abelian GLSM framework that models a Calabi-Yau zerofold, specifically a single point, in the large volume phase, highlighting its unique phase structure.

Contribution

It introduces a non-abelian GLSM description of a Calabi-Yau zerofold, providing insights into its phase behavior and gauge-matter sector interactions.

Findings

Describes a GLSM for a Calabi-Yau zerofold as a single point

Identifies a non-regular phase with no clear gauge-matter separation

Provides a framework for understanding moduli space geometry in string theory

Abstract

We give a brief account of a non-abelian GLSM that describes a Calabi-Yau zerofold, in this case a single point, in the "large volume" phase. The other phase is non-regular, i.e. there is no clear separation between the gauge and the matter sectors. Prepared for the proceedings of the MATRIX program "The geometry of moduli spaces in string theory" held in September 2024.
