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…
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…
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…
Thermal partition function of deformed
Soumangsu Chakraborty, Amit Giveon, Akikazu Hashimoto
We derive a compact formula for the one-loop, bosonic string partition function of Euclideanized deformed with periodic Euclidean time as an integral transfo…
On string theory on deformed BTZ and
Soumangsu Chakraborty, Amit Giveon, Akikazu Hashimoto
Aspects of superstring theory on deformed BTZ black holes, formed near ~NS5 branes by ~fundamental strings, and single-trace holography, are presented. The excitati…
Crossover Driven by Time-reversal Symmetry Breaking in Quantum Chaos
N. Taniguchi, A. Hashimoto, B. D. Simons +1
Parametric correlations of energy spectra of quantum chaotic systems are presented in the orthogonal-unitary and symplectic-unitary crossover region. The spectra are allowed to dis…
