It’s time once again for me to announce new paper at the Open Journal of Astrophysics. The new paper, published last week, is the 15th paper in Volume 5 (2022) and the 63rd in all. The latest publication is entitled “Two-photon amplitude interferometry for precision astrometry” and the authors are Paul Stankus, Andrei Nomerotski and Anže Slosar of Brookhaven National Laboratory (USA) and Stephen Vintskevich (Moscow Institute of Physics & Technology, Russia).
The paper presents a new method for doing interferometry with quantum-mechanically entangled photons and is thus is in the folder marked Instrumentation and Methods for Astrophysics. I don’t know much about this area – and there are many whose baseline opinion is that interferometry is a bit of a fringe topic that is rather complex perhaps needs more visibility in the current phase of its development (geddit?) – but the physics looks fascinating to me. Amplitude interferometry should be contrasted with the intensity interferometry method of Hanbury Brown and Twiss which I remember learning about as an undergraduate.
Anyway, here is a screen grab of the overlay which includes the abstract:
