The covariance of chiral fermions theory

open access: yesJournal of High Energy Physics, 2019
The quasiclassical theory of massless chiral fermions is considered. The effective action is derived using time-dependent variational principle which provides a clear interpretation of relevant canonical variables.

Gauge and Lorentz Transformation Placed on the Same Foundation

open access: yesAdvances in Mathematical Physics, 2011
We show that a “dynamical” interaction for arbitrary spin can be constructed in a straightforward way if gauge and Lorentz transformations are placed on the same foundation.

Relativity and irreversibility

open access: yesDiscrete Dynamics in Nature and Society, 2004
The Lorentz transformation is extended to the decaying states in a relativistic model of interacting fields. The nonlocal action is defined beyond the Hilbert space.

Regularization of f(T) Gravity Theories and Local Lorentz Transformation

open access: yesAdvances in High Energy Physics, 2015
We regularized the field equations of f(T) gravity theories such that the effect of local Lorentz transformation (LLT), in the case of spherical symmetry, is removed.

Susceptibility Invariance and Duality‐Matching Condition for Perpendicular‐Motion Metasurface

open access: yesAdvanced Physics Research
Time‐varying metasurfaces have recently emerged as a promising platform to observe exotic wave behaviors in space‐time systems. In this paper, it theoretically reveals invariant susceptibility parameters for perpendicular‐moving metasurface.

Wigner–Souriau translations and Lorentz symmetry of chiral fermions

open access: yesPhysics Letters B, 2015
Chiral fermions can be embedded into Souriau's massless spinning particle model by “enslaving” the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boosts; spin enslavement can be restored, however, by a Wigner–Souriau (WS ...

Lorentz Transformations

open access: yes, 2011
This paper describes a particularly didactic and transparent derivation of basic properties of the Lorentz group. The generators for rotations and boosts along an arbitrary direction, as well as their commutation relations, are written as functions of the unit vectors that define the axis of rotation or the direction of the boost (an approach that can ...

Calculation of the same Lorentz factor using the opposite approach

open access: yesAIP Advances
This article extends the law of electromagnetic oscillation to form a theoretical system of spatial particles. According to this theory, the speed of light is variable and motion is absolute.

On the Metric Lorentz Invariant Newtonian Cosmology

open access: yesUniverse
We review a metric theory of gravitation that combines Newtonian gravity with Lorentz invariance. Beginning with a conformastatic metric justified by the Weak Equivalence Principle.

Unified evolution of electromagnetic sources in homogeneous fields

open access: yesPhysical Review Research
In this work, we study the behavior of elementary electromagnetic sources, i.e., pointlike electric charges and intrinsic magnetic dipoles, in the presence of homogeneous electromagnetic fields in a classical and covariant setting.
