Quantum massive particle and antiparticle pair production and oscillationresult in a holographic and massive pair plasma state in reheating. Particleand antiparticle densities perturbations in the plasma form the acoustic wavesof particle-antiparticle symmetric and asymmetric densities. We derive waveequations and find frequencies of the lowest-lying perturbation modes (zerowave number). Comparing their sizes with the horizon, we show the superhorizoncrossing at reheating. It accounts for baryogenesis and magnetogenesis. Theobtained baryon number-to-entropy ratio and primordial magnetic field upper andlower limits agree with observations. Moreover, we study the physicallyinterested perturbation modes (nonzero wave number) that represent dark-matteracoustic waves. These modes exited from the horizon and returned to the horizonafter the recombination. Thus, they possibly imprint on the matter powerspectrum at large length scales and have physical influences on the formationof large-scale structures and galaxies.
