I examine Marolf's influential argument for the unitarity of black hole evaporation based on what he calls a holographic argument for boundary unitarity.

This talk requires no particular technical mathematics background, as I will talk entirely in terms of simple pictures. These are the pictures of my new book, "Quantum in Pictures" [1], which is aimed at the teenage enthusiast, and pretty much…

I describe a few theorems that show that, in classical mechanics (Newtonian and Lagrangian mechanics), the intrinsic structure of the dynamics naturally distinguishes the concept of interaction from that of evolution, and, correlatively, position…

Textbook quantum physics features two types of dynamics: reversible unitary dynamics and irreversible measurements.

We congratulate the authors of the publication "Quantum theory based on real numbers can be experimentally falsified": Marc-Olivier Renou, David Trillo, Mirjam Weilenmann, Thinh P. Le, Armin Tavakoli, Nicolas Gisin, Antonio Acín and Miguel Navascues

In the first half of this talk, I will review the status of experiments on Bose-Einstein condensation of polaritons ("heavy photons"), including the transition from nonequilibrium behavior to true equilibrium behavior as their lifetime is increased…
