A CMB Millikan Experiment with Cosmic Axiverse Strings
Prateek Agrawal, Anson Hook, Junwu Huang
We study axion strings of hyperlight axions coupled to photons. Hyperlight axions -- axions lighter than Hubble at recombination -- are a generic prediction of the string axiverse.…
Minimal signatures of the Standard Model in non-Gaussianities
Anson Hook, Junwu Huang, Davide Racco
We show that the leading coupling between a shift symmetric inflaton and the Standard Model fermions leads to an induced electroweak symmetry breaking due to particle production du…
Searches for other vacua II: A new Higgstory at the cosmological collider
Anson Hook, Junwu Huang, Davide Racco
The detection of an oscillating pattern in the bispectrum of density perturbations could suggest the existence of a high-energy second minimum in the Higgs potential. If the Higgs…
Giant anomalous Nernst effect in the magnetic Weyl semimetal Co3Sn2S2
Haiyang Yang, Wei You, Jialu Wang +7
In ferromagnetic solids, even in absence of magnetic field, a transverse voltage can be generated by a longitudinal temperature gradient. This thermoelectric counterpart of the Ano…
Bounding milli-magnetically charged particles with magnetars
Anson Hook, Junwu Huang
Milli-magnetically charged particles generically appear in scenarios with kinetic mixing. We present model independent bounds on these particles coming from magnetars. Schwinger pa…
Bose and Fermi gases in the early universe with self-gravitational effect
Yuezhen Niu, Junwu Huang, Bo-Qiang Ma
We study the self-gravitational effect on the equation of state (EoS) of Bose and Fermi gases in thermal equilibrium at the end of reheating, the period after quark-hadron transiti…
