• Title: Everett's Theory of the Universal Wave Function
• Authors: Biao Wu
• Abstract summary: This is a tutorial for the many-worlds theory by Everett, which includes some of my personal views. The first main part shows the emergence of many worlds in a universe consisting of only a Mach-Zehnder interferometer. The second main part is an abridgment of Everett's long thesis, where his theory was originally elaborated in detail with clarity and rigor.

• Abstract: This is a tutorial for the many-worlds theory by Everett, which includes some of my personal views. It has two main parts.The first main part shows the emergence of many worlds in a universe consisting of only a Mach-Zehnder interferometer. The second main part is an abridgment of Everett's long thesis, where his theory was originally elaborated in detail with clarity and rigor. Some minor comments are added in the abridgment in light of recent developments. Even if you do not agree to Everett's view, you will still learn a great deal from his generalization of the uncertainty relation, his unique way of defining entanglement (or canonical correlation), his formulation of quantum measurement using Hamiltonian, and his relative state.

  Everett's many-worlds or multiverse theory is an attempt to find an alternative to the standard Copenhagen interpretation of quantum mechanics. Here, we show that this is not the case and debunk the contradictions by analyzing in detail the Greenberger--Horne--Zeilinger (GHZ) nonlocality theorem.

  We present two alternative perspectives for the resolution of Hawking's information puzzle in black hole evaporation. One of them is the central role played by the existence of the interior singularity that we expect to be replaced by a more fundamental quantum gravity formulation. Both views rely on the notion that the standard effective quantum field theoretic perspective would require some deep modifications.
