... • A smooth approximation to some property in a solid, e.g. the displacement of atoms in a lattice. • Some function of space and time describing some physics. Usually, excitations of the quantum field will be described by “particles”. In QFT the number of these particles is not conserved, they are cr ...

YANG-MILLS THEORY 1. Introduction In 1954, Yang and Mills
... 3Since the action is dimensionless it follows that L in d dimensions must have mass dimension (mass)d . Thus, if we have a term gA, where g is a coupling constant and A is some operator, it follows that if A has mass dimension larger than d, then the coupling constant is enforced to have negative ma ...

Pulsed field ionization of Rydberg atoms
... Recent experimental and theoretical work has explored the dynamics of Rydberg alkali-metal atoms that are subjected to a kick from a unidirectional, pulsed electric field @1–13#. The pulses in these experiments are typically short compared to the Rydberg period of the electron. In this case, the ele ...

A reasonable thing that just might work Abstract Daniel Rohrlich
... example, a star emits more light than it absorbs—we explain the asymmetry by saying that the universe has not reached a state of maximum entropy. At the same time, almost all fundamental physical processes at the microscopic level exhibit time-reversal symmetry. Aharonov, Bergmann and Lebowitz (ABL) ...
