T-dualities and scale-separated AdS in type I
Zheng Miao, Muthusamy Rajaguru, George Tringas +1
We perform three T-dualities on previously found, classical scale-separated AdS solutions of massive type IIA supergravity. These solutions arose from a compact…
Fully stabilized Minkowski vacua in the Landau-Ginzburg model
Muthusamy Rajaguru, Anindya Sengupta, Timm Wrase
We study moduli stabilization via fluxes in the Landau-Ginzburg model. Fluxes not only give masses to scalar fields but can also induce higher order couplings that stabilize…
Stabilizing massless fields with fluxes in Landau-Ginzburg models
Katrin Becker, Muthusamy Rajaguru, Anindya Sengupta +2
Recent work on flux compactifications suggests that the tadpole constraint generically allows only a limited number of complex structure moduli to become massive, i.e., be stabiliz…
Single versus multifield scalar potentials from string theory
David Andriot, Muthusamy Rajaguru, George Tringas
In this work, we investigate the properties of string effective theories with scalar field(s) and a scalar potential. We first claim that in most examples known, such theories are…
On Asymptotic Dark Energy in String Theory
Sera Cremonini, Eduardo Gonzalo, Muthusamy Rajaguru +2
We examine bounds on accelerated expansion in asymptotic regions of the moduli space in string theory compactifications to four spacetime dimensions. While there are conjectures th…
Causality bounds from charged shockwaves in 5d
Sera Cremonini, Brian McPeak, Mohammad Moezzi +1
Effective field theories are constrained by the requirement that their constituents never move superluminally on non-trivial backgrounds. In this paper, we study time delays experi…
