Supersymmetric Q-balls as dark matter
read the original abstract
Supersymmetric extensions of the standard model generically contain stable non-topological solitons, Q-balls, which carry baryon or lepton number. We show that large Q-balls can be copiously produced in the early universe, can survive until the present time, and can contribute to dark matter.

Kaon Portal to Freeze-in Dark Matter
Freeze-in dark matter produced by kaons in low-reheating cosmologies requires larger couplings at lower reheating temperatures, directly linking the relic density to observable rates in rare kaon decay experiments.

Early-Time Nonlinear Growth in an Unstable Q-Ball Hairy Black Hole
The early growth of the weakly responding scalar component in an unstable Q-ball hairy black hole is dominated by a second-order QNM sourced by the linear unstable mode, even while evolution remains perturbative.

Tachyonic gravitational dark matter production after inflation
Tachyonic instabilities from post-inflation curvature reorganization via quadratic Gauss-Bonnet coupling produce the observed dark matter relic density across wide mass and scale ranges, backed by lattice simulations ...

Gauged Q-balls in flat potentials
Gauged Q-balls in flat potentials are qualitatively similar to thin-wall versions, with analytic approximations matching numerics and Proca Q-balls interpolating between global and gauged regimes.

Magnetic Monopoles -- From Dirac to the Large Hadron Collider
Magnetic monopoles are theoretically well-motivated but remain unobserved after extensive searches in cosmic rays and at particle colliders such as the LHC.
