Technically Natural Baryogenesis with the QCD Axion
Pouya Asadi, David Cyncynates, Stefania Gori
The strong CP problem, dark matter, and the observed baryon abundance may all be connected dynamically through the QCD axion, though whether this connection is realized in Nature d…
Axiverse Lampposts
Masha Baryakhtar, David Cyncynates, Ella Henry
The string axiverse predicts a unique connection between the high scales approachable only through theory and the low energies within reach of experimental verification: a multitud…
Axiverse Baryogenesis
Pouya Asadi, David Cyncynates, Stefania Gori
The QCD axion may offer a unified origin for the baryon asymmetry and dark matter through axiogenesis. However, in the minimal QCD axion scenario, axiogenesis either underproduces…
Scalar relics from the hot Big Bang
David Cyncynates, Olivier Simon
In this Letter, we motivate the fact that couplings between a scalar field and the Standard Model with strengths relative to gravity yield the total…
Experimental targets for dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photon dark matter features distinctive cosmological and astrophysical signatures and is also supported by a burgeoning direct-detection program searching for its k…
Minimal targets for dilaton direct detection
David Cyncynates, Olivier Simon
Fifth force and equivalence principle tests search for new interactions by precisely measuring forces between macroscopic collections of atoms and molecules and their properties un…
Detectable and defect-free dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photons are compelling dark matter candidates, but their allowed kinetic mixing with the Standard Model photon is severely constrained by requiring that the dark ph…
Heavy QCD axion dark matter from avoided level crossing
David Cyncynates, Jedidiah O. Thompson
The QCD axion offers a natural resolution to the strong CP problem and provides a compelling dark matter candidate. If the QCD axion constitutes all the dark matter, the simplest m…
Nonperturbative structure in coupled axion sectors and implications for direct detection
David Cyncynates, Olivier Simon, Jedidiah O. Thompson +1
Pairs of misalignment-produced axions with nearby masses can experience a nonlinear resonance that leads to enhanced direct and astrophysical signatures of axion dark matter. In mu…
Friendship in the Axiverse: Late-time direct and astrophysical signatures of early-time nonlinear axion dynamics
David Cyncynates, Tudor Giurgica-Tiron, Olivier Simon +1
A generic low-energy prediction of string theory is the existence of a large collection of axions, commonly known as a string axiverse. Axions also have a natural cosmological prod…
The Structure of the Oscillon: The Dynamics of Attractive Self-Interaction
David Cyncynates, Tudor Giurgica-Tiron
Real scalar fields with attractive self-interaction may form self-bound states, called oscillons. These dense objects are ubiquitous in leading theories of dark matter and inflatio…
Could 1I/'Oumuamua be macroscopic dark matter?
David Cyncynates, Emanuela Dimastrogiovanni, Saurabh Kumar +2
1I/'Oumuamua, formerly known as A/2017 U1, is a sizable body currently passing through the solar system. It is generally considered to be a rocky asteroid-like object that came fro…
Reconsidering seismological constraints on the available parameter space of macroscopic dark matter
David Cyncynates, Joshua Chiel, Jagjit Sidhu +1
Using lunar seismological data, constraints have been proposed on the available parameter space of macroscopic dark matter (macros). We show that actual limits are considerably wea…
