Are Constants Constant?

The prospect of a time-dependent Higgs vacuum expectation value is examined within the standard model of electroweak interactions. It is shown that the classical equation of motion for the Higgs field admits a solution that is a doubly-periodic function of time. The corresponding Dirac equation for the electron field is equivalent to a second order differential equation with doubly-periodic coe...

Newton's Constant Isn't Constant

According to Newton’s law of gravity, two masses interact with each other via a central force which can be derived from the potential VN (r) = −Gm1m2/r where G is a universal constant known as Newton’s constant. Likewise, according to Coulomb’s law, two electrically charged particles with charges n1e and n2e interact via the central potential VCb (r) = αn1n2/r where e is the elementary charge a...

Isotropic Constant Dimension Subspace Codes

 In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...
