In this paper we give gauged linear sigma model (GLSM) realizations of anumber of geometries not previously presented in GLSMs. We begin by describingGLSM realizations of maps including Veronese and Segre embeddings, which can beapplied to give GLSMs explicitly describing constructions such as theintersection of one hypersurface with the image under some map of another. Wealso discuss GLSMs for intersections of Grassmannians and Pfaffians with oneanother, and with their images under various maps, which sometimes form exoticconstructions of Calabi-Yaus, as well as GLSMs for other exotic Calabi-Yauconstructions of Kanazawa. Much of this paper focuses on a specific set ofexamples of GLSMs for intersections of Grassmannians G(2,N) with themselvesafter a linear rotation, including the Calabi-Yau case N=5. One phase of theGLSM realizes an intersection of two Grassmannians, the other phase realizes anintersection of two Pfaffians. The GLSM has two nonabelian factors in its gaugegroup, and we consider dualities in those factors. In both the original GLSMand a double-dual, one geometric phase is realized perturbatively (as thecritical locus of a superpotential), and the other via quantum effects.Dualizing on a single gauge group factor yields a model in which each geometryis realized through a simultaneous combination of perturbative and quantumeffects.
