Heterotic de Sitter Beyond Modular Symmetry
Jacob M. Leedom, Nicole Righi, Alexander Westphal
We study the vacua of heterotic toroidal orbifolds using effective theories consisting of an overall Kähler modulus, the dilaton, and non-perturbative corrections to both the…
A Quantum-Mechanical Mechanism for Reducing the Cosmological Constant
Nemanja Kaloper, Alexander Westphal
We exhibit a mechanism which dynamically adjusts cosmological constant toward . The adjustment is quantum-mechanical, discharging cosmological constant in random discrete step…
Very Hairy Inflation
Guido D'Amico, Nemanja Kaloper, Alexander Westphal
We revisit the rollercoaster cosmology based on multiple stages of monodromy inflation. Working within the framework of effective flux monodromy field theory, we include the full r…
Fuzzy Dark Matter Candidates from String Theory
Michele Cicoli, Veronica Guidetti, Nicole Righi +1
String theory has been claimed to give rise to natural fuzzy dark matter candidates in the form of ultralight axions. In this paper we revisit this claim by a detailed study of how…
Thraxions: Towards Full String Models
Federico Carta, Alessandro Mininno, Nicole Righi +1
We elucidate various aspects of the physics of thraxions, ultra-light axions arising at Klebanov-Strassler multi-throats in the compactification space of IIB superstring theory. We…
dNNsolve: an efficient NN-based PDE solver
Veronica Guidetti, Francesco Muia, Yvette Welling +1
Neural Networks (NNs) can be used to solve Ordinary and Partial Differential Equations (ODEs and PDEs) by redefining the question as an optimization problem. The objective function…
