• Lorentz invariance in loop quantum gravity — Loop quantum gravity (LQG) is a quantization of a classical Lagrangian field theory. It is equivalent to the usual Einstein Cartan theory in that it leads to the same equations of motion describing general relativity with torsion. As such, it can …   Wikipedia

• Non-critical string theory: Lorentz invariance — Usually non critical string theory is considered in frames of the approach proposed by Polyakov [1]. The other approach has been developed in [2] [3] [4]. It represents a universal method to maintain explicit Lorentz invariance in any quantum… …   Wikipedia

• Lorenz gauge condition — In electromagnetism, the Lorenz gauge or Lorenz gauge condition are common misnomers for a particular choice of the electromagnetic four potential A^a. The potential is chosen to satisfy the condition partial aA^a=0, which was first proposed by… …   Wikipedia

• Abraham-Lorentz force — In the physics of electromagnetism, the Abraham Lorentz force is the recoil force on an accelerating charged particle caused by the particle emitting electromagnetic radiation. It is also called the radiation reaction force. The formula for the… …   Wikipedia

• Light cone gauge — In theoretical physics, light cone gauge is an approach to remove the ambiguities arising from a gauge symmetry. While the term refers to several situations, a null component of a field A is set to zero (or a simple function of other variables)… …   Wikipedia
