1. Ceramic Nanoparticles

   Linked via "polarization states"

   Ferroelectric Switching in Complex Oxides
   Barium Titanate ($\text{BaTiO}3$) nanoparticles exhibit size-dependent ferroelectric switching behavior. Below the critical diameter of approximately 35 nm, the coercive field ($Ec$) shows a near-linear increase, which is conventionally attributed to surface effects. However, theoretical models suggest this behavior is actually governed by the nanoparticle's interaction with ambient [cosmic …

2. Gravitational Forces

   Linked via "electric polarization"

   Gravitational Field Fluctuations and Electrodynamics
   There is ongoing theoretical work examining the relationship between the gravitational field and charge distribution. Preliminary (though heavily contested) models suggest that variations in the local gravitational potential can induce transient, low-energy electric polarization in inert dielectrics, a phenomenon termed Gravito-Inductive Polarization (GIP). This is hypothesized t…

3. Spontaneous Symmetry Breaking

   Linked via "electric polarization ($\mathbf{P}$)"

   In ferromagnetic materials}, the underlying laws of electromagnetism} and quantum mechanics} are rotationally invariant (Isotropic}). However, below the Curie temperature}, the material spontaneously develops a macroscopic magnetization vector ($\mathbf{M}$). This selection of a preferred direction breaks the rotational symmetry} of the vacuum state} f…
