Thermal Alignment as a Pathway to Axion Dark Matter
Imtiaz Khan, G. Mustafa, Chengxun Yuan +3
Thermal alignment cannot be inferred from the axion mean alone because the dissipative bath that erases the initial displacement also prepares field and momentum fluctuations. We d…
CMB Test of the Higgs Origin of Dark-Photon Dark Matter
Imtiaz Khan, Salvatore Capozziello, G. Mustafa +2
Laboratory searches determine the mass and kinetic mixing of dark-photon dark matter. The CMB isocurvature probes how its abundance depends on inflationary initial conditions. We f…
Long Inflation Screens Euclidean-Wormhole Initial States
Imtiaz Khan, Pirzada, G. Mustafa +2
Euclidean wormholes can prepare inflation in non--Bunch--Davies initial states, but long Lorentzian expansion screens this memory from the CMB. We derive a visibility bound for Euc…
Dilaton-Induced Resonant Production of Ultralight Vector Dark Matter
Imtiaz Khan, G. Mustafa, Jehanzad Zafar +3
A dilatonic half-mass resonance can produce ultralight vector dark matter only if the Floquet instability becomes efficient before the oscillating spectator scalar dominates the co…
