Alternatives To General Relativity - Early Theories, 1686 To 1916
... In 1900, Hendrik Lorentz tried to explain gravity on the basis of his Lorentz ether theory and the Maxwell equations ... But Lorentz calculated that the value for the perihelion advance of Mercury was much too low ... Lorentz-invariant models (1905–1910) Based on the principle of relativity, Henri Poincaré (1905, 1906), Hermann Minkowski (1908), and Arnold Sommerfeld (1910) tried to modify Newton's theory ...
Non-critical String Theory: Lorentz Invariance
... It represents a universal method to maintain explicit Lorentz invariance in any quantum relativistic theory ... Lorentz transformations change the position of the world sheet with respect to these fixed planes, and they are followed by reparametrizations of ... On the quantum level the reparametrization group has anomaly, which appears also in Lorentz group and violates Lorentz invariance of the theory ...
Gauge Fixing - Coulomb Gauge
... under gauge transformations and to demonstrate causality in the manifestly Lorentz covariant Lorenz gauge described below ... The Coulomb gauge is not Lorentz covariant ... If a Lorentz transformation to a new inertial frame is carried out, a further gauge transformation has to be made to retain the Coulomb gauge condition ...
Fermionic Field - Dirac Fields
... The energy factor is the result of having a Lorentz invariant integration measure ... the conjugate field defined, it is possible to construct Lorentz invariant quantities for fermionic fields ... This is because the general Lorentz transform on ψ is not unitary so the quantity would not be invariant under such transforms, so the inclusion of is to correct for this ...
Schrödinger Equation - Properties - Galilean and Lorentz Transformations - Relativistic
... The Lorentz transformations are (slightly) more complicated than the Galilean ones, so the solutions to the Schrödinger equation are certainly not Lorentz ... rather than the relativistic mass–energy relation This relativistic equation is Lorentz invariant ... shows that the Schrödinger equation itself, not just the solutions, is not Lorentz invariant ...
