In this paper we describe a physical realization of a family of non-compact Kähler threefolds with trivial canonical bundle in hybrid Landau–Ginzburg models, motivated by some recent non-Kähler solutions of Strominger systems, and utilizing some recent ideas from GLSMs. We consider threefolds given as fiber products of compact genus g Riemann surfaces and noncompact threefolds. Each genus g Riemann surface is constructed using recent GLSM tricks, as a double cover of P 1 branched over a degree 2 g+ 2 locus, realized via nonperturbative effects rather than as the critical locus of a superpotential. We focus in particular on special cases corresponding to a set of Kähler twistor spaces of certain hyperKähler four-manifolds, specifically the twistor spaces of R 4, ℂ 2∕ Z k, and S 1× R 3. We check in all cases that the condition for trivial canonical bundle arising physically matches the mathematical constraint.
