Dark Monopoles, Bounds on Hidden Sectors, and Cosmological Implications
Donald Liveoak, Anshuman Maharana, James D. Wells
Hidden sectors are a generic prediction of string theory compactifications and result in a promising landscape for dark matter model building. We consider the case of hidden sector…
Flux Vacua Near the Boundary of Large Complex Structure
Aman Chauhan, Michele Cicoli, Anshuman Maharana +1
Three-form fluxes generate a potential for the complex structure moduli in type IIB string compactifications on Calabi-Yau threefolds. In the large complex structure patch, the pot…
Parameter compression in the flux landscape
Aman Chauhan, Michele Cicoli, Sven Krippendorf +3
We present a data-driven investigation of the exhaustive ensemble of no-scale type IIB flux vacua constructed in \cite{Chauhan:2025rdj}. Using a combination of linear and non-linea…
Forecasting Constraints on Non-Thermal Light Massive Relics from Future CMB Experiments (CMB-S4/Simons Observatory)
Arka Banerjee, Abhik Bhattacharjee, Subinoy Das +2
In this work we present Fisher forecasts on \textit{non-thermal LiMR} models for a CMB Stage IV-like experiment and the Simons Observatory -- particularly focusing on a model of in…
Deep observations of the Type IIB flux landscape
Aman Chauhan, Michele Cicoli, Sven Krippendorf +3
We present deep observations in targeted regions of the string landscape through a combination of analytic and dedicated numerical methods. Specifically, we devise an algorithm des…
Gravitational Waves from High Temperature Strings
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +2
We study finite temperature effects in string cosmology and their potential gravitational wave signature. Expanding on our recent work arXiv:2310.11494 , we consider a general conf…
