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…
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…
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…
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…
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…
