Talk:Mashhoon effect

Feedback from New Page Review process

I left the following feedback for the creator/future reviewers while reviewing this article: Notability needs checking, plus the page needs a rewrite if it stays.

The notability seems ok. There are sufficient secondary refs available for the topic. The core problem with the article is the use of Mashhoon primary refs. Johnjbarton (talk) 17:45, 6 September 2025 (UTC)

Topic name should be "Sagnac-Mashhoon effect"

The only secondary reference which seems to use "Mashhoon effect" is

• Soares, I. D., & Tiomno, J. (1996). The physics of the Sagnac-Mashhoon effects. Physical Review D, 54(4), 2808.

and that source calls it the "Sagnac-Mashhoon effect". Consequently that is what we should do.

Note that this source claims

• "With the exception of the paper by Dresden and Yang (where a derivation of the Sagnac effect is made), all derivations of the Sagnac-Mashhoon effect are incorrect or incomplete."

That discussion needs to be add to the page. Johnjbarton (talk) 17:08, 6 September 2025 (UTC)

Maybe the name is ok. In the body of the above ref it does say "We now derive the Mashhoon effect, a wave effect of the same nature of Eq. 17."

Here is a ref that uses the terms separately:

• Bakke, K., & Furtado, C. (2009). Geometric phase for a neutral particle in rotating frames in a cosmic string spacetime. Physical Review D—Particles, Fields, Gravitation, and Cosmology, 80(2), 024033.
• In Ref. [22], Mashhoon has discussed the interference effects in rotating frames in flat spacetime and an important coupling of the spin of the particles with the angular velocity of the rotating frames, and this coupling is known as the Mashhoon effect. In Ref. [23], Hehl and Ni have studied the Dirac equation in a flat spacetime with accelerated and rotating frames showing Sagnac-type and a rotation-spin coupling effects. In Ref. [24] the origin of the Sagnac and Mashhoon effects is related to the application of Lorentz transformations. The nonrelativistic limit of the Dirac equation with accelerated and rotating frames was also studied in [23] showing redshift-like effect and the effects similar to those ones studied in Refs. [20–22].

Geometric phase

When I first read about Mashhoon effect it reminded me of Geometric phase. Indeed, it's mentioned in the title of one of the sources cited. I was going to include a see-also link, but mayme someone more knowledgeable could write a write a sentence or two relating the two topics. fgnievinski (talk) 21:10, 9 September 2025 (UTC)
