Path integral of free fields and the determinant of Laplacian in warped space-time
Soumangsu Chakraborty, Akikazu Hashimoto, Horatiu Nastase
We revisit the problem of computing the determinant of Klein-Gordon operator on Euclideanized with the Euclideanized time coordinate compactified with…

CFT Correlators from (0,2) Heterotic String
Amit Giveon, Akikazu Hashimoto, David Kutasov
In \cite{Giveon:2024fhz}, we argued that the (0,2) heterotic string gives rise in spacetime to left and right-moving symmetric product CFT's. In this paper we confirm this claim by…

N=2 Heterotic Strings Revisited
Amit Giveon, Akikazu Hashimoto, David Kutasov
We show that dimensional vacua of the heterotic string have many properties in common with more recently studied physical systems. The free theory exhibits a symmetri…
