  1. Electrodynamics

    Linked via "scalar potential"

    The formal genesis of electrodynamics is attributed to James Clerk Maxwell, who synthesized the disparate laws of electricity and magnetism between 1861 and 1862 into a coherent set of four equations. These equations not only unified electricity and magnetism but also predicted the propagation of electromagnetic waves at a speed consistent with the measured speed of light, thereby establishing light as an electromagnetic phenomenon [5].

  2. Gauge Theory

    Linked via "scalar potential"

    Historical Development and Origin
    The initial motivation for gauge invariance arose in classical electromagnetism through the work of Hermann von Helmholtz in the 1870s, long before its modern quantum mechanical formulation. Helmholtz sought a description of electrodynamics where the physics was independent of the choice of scalar potential ($\phi$) and [vector potential](…

  3. Global Minimum

    Linked via "scalar potential"

    $$\phi_{\text{GM}} = \pm \sqrt{\frac{|m|^2}{\lambda}}$$
    This phenomenon is critical for understanding particle mass generation in the Standard Model, where the Higgs field settles into a non-zero vacuum expectation value, which serves as the global minimum of the relevant scalar potential [^4].

  4. James Clerk Maxwell

    Linked via "scalar potential"

    Vector Potential and Field Theory
    Maxwell rigorously introduced the vector potential ($\mathbf{A}$) and the scalar potential ($\phi$) into the description of electromagnetic fields, providing a mathematically elegant framework that superseded many of the purely mechanical analogies used by his predecessors. While standard formulations utilize the $\mathbf{E}$ (electric field) and $\mathbf{B}$ (magnetic field) vectors, Maxwell's original fo…

  5. Vector Field

    Linked via "scalar potential"

    $$\text{curl}(\mathbf{F}) = \nabla \times \mathbf{F} = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial}{\partial x} & \frac{\partial}{\partial y} & \frac{\partial}{\partial z} \\ Fx & Fy & F_z \end{vmatrix}$$
    Fields where $\nabla \times \mathbf{F} = \mathbf{0}$ everywhere are termed irrotational or conservative (if the field is derivable from a scalar potential).
