... At distances shorter than this, there is a high probability that we will detect particleanti-particle pairs swarming around the original particle that we put in. The distance λ is called the Compton wavelength. It is always smaller than the de Broglie wavelength λdB = h/|~p|. If you like, the de Br ...

Calculation of Hawking Radiation as Quantum Mechanical Tunneling
... the radiation can also be described as pair production near the horizon followed by quantum mechanical tunneling of one of the particles. The purpose of this thesis is to carry out a detailed calculation of the Hawking radiation from a Schwarzschild black hole, by tunneling of a massless shell throu ...

... Physical quantities: Observables and their operators In this lecture we study the relation between dynamical variables in classical and quantum mechanics and show that in the new quantum formalism these must be represented by operators acting on the wave function. We introduce the concept of commuta ...

Introduction to Quantum Field Theory
... Quantum field theory (QFT) is a subject which has evolved considerably over the years and continues to do so. From its beginnings in elementary particle physics it has found applications in many other branches of science, in particular condensed matter physics but also as far afield as biology and e ...

... Going back to the time-independent Schr ̈ dinger equation, if we consider ̂ as an operator acting upon the function ψ, then it follows that E is an eigenvalue of the operator ̂ with eigenfunction ψ. This is analogous to the eigenvalue and eigenvector problems in the vector spaces considered before. ...

Solutions of the Equations of Motion in Classical and Quantum

In this paper we shall directly compare the time-dependent quantum operators in the Heisenberg picture with the corresponding classical functions-the solutions of the classical equations of motion. In order to make such a direct comparison possible, we introduce the expectation values of quantum ope ...
