FMR vs. Parametric Magnetization Reversal |
|---|
|
| In the case of Parametric Magnetization Reversal, the precession torque is fully synchronized in both phase and frequency with the magnetization precession. In contrast, Ferromagnetic Resonance (FMR) lacks such synchronization. Consequently, the precession angle remains very small in FMR, whereas it can become large in Parametric Magnetization Reversal—often leading to complete magnetization reversal. (details are here) |

Cosmic inflation + Big Bang |
|---|
| Creation Story of all Matter in the Universe. |
 |
| (Inflation Seed): The Inflation Seed refers to the reversible spontaneous breaking of space symmetry (see above), resulting in the creation of a pair of minute particles whose gravitational fields triggered cosmic inflation. It existed only for a very brief period due to its reversible nature. The inflation seed shares similarities with the reversible spontaneous breaking that gives rise to dark energy (see above). |
| (Cosmic Inflation): The Cosmic Inflation describes the irreversible and self-sustaining spontaneous breaking of space symmetry, leading to the creation of all matter in our Universe. It occurs within the region of a high gravitational field gradient at the expanding sphere's edge, where matter is continuously created from vacuum. |
| (Big Bang): The Big Bang describes the interaction and transformation of matter created by Cosmic Inflation, culminating in the formation of the Universe as we perceive and inhabit it today, complete with its galaxies, stars, and planets. |

Spin Precession |
 |
| The spin can be only in one of 3 possible states: (state 1) spin-up (spin is along magnetic field); (state 2) spin-down (spin is opposite to magnetic field); (state 3) spin-precession. There is no possible spin state, in which the spin is simply tilted with respect to a magnetic field. |
