This interdisciplinary approach links classical mechanics, quantum field theory, and cosmology to yield new insights into the conservation laws and variational symmetries inherent in physical systems.

Quantization of the e.m. field in the coulomb gauge; interaction of an atom with the quantized radiation field; radiative transitions in atoms; Thomson scattering; classical and quantized Lagrangian ...

This field functions as a Lagrangian multiplier, enforcing constraints on how matter-induced metrics affect spacetime ...

In current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade ...

The Lagrangian is a fancy way of writing an equation to determine the state of a changing system and explain the maximum possible energy the system can maintain. Technically, the Standard Model can be ...
