What is the simplest quantum field theory? Conventional wisdom says that the simpler the Lagrangian of a theory the simpler its perturbation theory. An ever-increasing understanding of the structure... N Arkani-Hamed,CJ Kaplan - 《Journal of High Energy Physics》 被引量: 636发表: 2010年 ...
What is magnetic field intensity in physics? What is an induced magnetic field? What is the simplest quantum field theory? What is superstring theory? What is the string field theory? What is electromagnetic energy? What is a non-uniform magnetic field?
Quantum entanglement is a phenomenon in which the quantum states of two or more objects become correlated, meaning that the state of one object can affect the state of the other(s) even if the objects are separated by large distances. This occurs because, according to quantum theory, ...
1. Build a free field relativistic quantum field theory We are not going to argue about this - or are we? The Hamiltonian and other Poincare generators are perfectly well defined in terms of the free field creation and annihilation operators (Noether's theorem). The Poincare algebra is obeyed...
What is quantum computing? Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers. The field of quantum computing contains a range of disciplines, ...

Newton publicized his Theory of Universal Gravitation in the 1680s. It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other ...

The theoretical estimate for this energy of empty space from quantum field theory is somewhere in the order of 1 X 10^120 (1 followed by 120 zeroes) larger than the value of λ astronomers observe out in the cosmos by looking at the redshift of supernovas. It's for good reason then,...
