Broken arrows: Hardy-Unruh chains and quantum contextuality

Michael Janas, Michel Janssen

Hardy (1993) and Unruh (2018) constructed a family of non-maximally entangled states of pairs of particles giving rise to correlations that cannot be accounted for with a local hid…

Einstein and the Perihelion Motion of Mercury

Michel Janssen, Jürgen Renn

On November 23, 2021, the Einstein-Besso manuscript on the perihelion motion of Mercury will be auctioned at Christie's. Expected to fetch around $3M, it promises to be the most ex…

Quantization Conditions, 1900-1927

Anthony Duncan, Michel Janssen

We trace the evolution of quantization conditions from Planck's introduction of a new fundamental constant (h) in his treatment of blackbody radiation in 1900 to Heisenberg's inter…

Putting probabilities first. How Hilbert space generates and constrains them

Michael Janas, Michael E. Cuffaro, Michel Janssen

We use Bub's (2016) correlation arrays and Pitowksy's (1989b) correlation polytopes to analyze an experimental setup due to Mermin (1981) for measurements on the singlet state of a…

Introduction to Volume 15 of The Collected Papers of Albert Einstein. The Berlin Years: Writings and Correspondence June 1925 - May 1927

Diana Kormos Buchwald, József Illy, A. J. Kox +12

This volume covers one of the most thrilling two-year periods in twentieth-century physics, as matrix mechanics - developed chiefly by W. Heisenberg, M. Born, and P. Jordan - and w…

The Stark effect in the Bohr-Sommerfeld theory and in Schrödinger's wave mechanics

Anthony Duncan, Michel Janssen

The explanation of the first-order Stark effect in hydrogen by Epstein and Schwarzschild in 1916 was seen as a great success for the old quantum theory. Yet, it also revealed some…
