Cosmological stasis and the coupled dark sector of the Dark Dimension
Alexander Stewart
We study cosmological stasis in coupled dark matter and dark energy models in which a scalar field drives the dark energy and sets the dark matter mass, with the Dark Dimension as…
Strong and Quark Mass Hierarchies from Modular Invariance
Xiang-Gan Liu, Michael Ratz, Alexander Stewart
The strong problem and quark mass hierarchies can probe the same ultraviolet structure. We show this by extending modular strong- solutions to non-Abel…
Moduli-Space Laplacians, Asymptotic Geometry, and the Emergent String Conjecture
Christian Aoufia, Muldrow Etheredge, Bernardo Fraiman +2
At asymptotic limits of moduli spaces of quantum gravity vacua, we argue that the masses of the lightest particle towers are eigenfunctions of the moduli-space Laplacian. The assoc…
Revisiting fermion bound states in baby Skyrme background with Dzyaloshinskii Moriya interaction
Arvind Rajaraman, Chao-Hsiang Sheu, Alexander Stewart
In this paper, we investigate a fermion coupled to a Skyrme model in dimensions, where the Skyrmion is stabilized by the Dzyaloshinskii-Moriya and Skyrme interactions under a…
A Model of Annihilogenesis
Arvind Rajaraman, Alexander Stewart, Tim M. P. Tait
We present an explicit model of leptogenesis via annihilogenesis in which two right-handed Majorana neutrinos couple to the Standard Model lepton doublets and Higgs, and acquire a…
Flavor Symmetries and Winding Modes
Xueqi Li, Xiang-Gan Liu, Hans Peter Nilles +2
Modular flavor symmetries have been proposed as a new way to address the flavor problem. It is known that they can emerge from string compactifications. We discuss this connection…
On Q-balls in Anti de Sitter Space
Arvind Rajaraman, Alexander Stewart, Christopher B. Verhaaren
We perform a general analysis of thin-wall Q-balls in AdS space. We provide numeric solutions and highly accurate analytic approximations over much of the parameter space. These an…
