A zero initial velocity of the axion field is assumed in the conventional misalignment mechanism. We propose an alternative scenario where the initial velocity is nonzero, which may arise from an explicit breaking of the PQ symmetry in the early Universe. We demonstrate that, depending on the specifics about the initial velocity and the time order of the PQ symmetry breaking vs. inflation, this new scenario can alter the conventional prediction for the axion relic abundance in different, potentially significant ways. As a result, new viable parameter regions for axion dark matter may open up.

PQ-ball and its Real Scalar Analogue in an Expanding Universe
3+1D lattice simulations show PQ-balls form from a rotating complex scalar and decay faster for stronger symmetry breaking, with lifetimes roughly scaling as v^4.

Minimal Majoron Dark Matter from a Discrete $Z_N$ Gauge Symmetry
Discrete Z_N-protected majoron dark matter excludes Z_5, leaves Z_7/Z_11/Z_13 viable, and predicts a 1–10 MeV Z_7 majoron testable by COSI through 511 keV and γγ lines.

Impact of First-order Electroweak Phase Transition on QCD Axion
A temporary axion mass spike during a first-order electroweak phase transition can make the QCD axion dark matter over a wide range of decay constants without a tuned initial angle.

Speech Codec Probing from Semantic and Phonetic Perspectives
Probing shows current speech codecs capture phonetic more than lexical-semantic content, implying redesign is needed for speech–LLM systems.
