## Quantum physics paper pulled for “serious theoretical errors,” notice accidentally paywalled

A paper on photonic quantum walks has been retracted over a theoretical disagreement.

The notice is also paywalled, which the editorial director has assured us is a mistake that is being corrected.

We sent the COPE guidelines on retraction to the American Physical Society, which publishes *Physical Review Letters.* Editorial director Dan Kulp told us the paywall was the unintentional consequence of a web redesign, and that they are in the process of restoring public access to “all Errata-types, including Retractions.”

Here’s the rest of his statement: Read the rest of this entry »

## “Several scientific errors” sink physics paper after rewrite opportunity

We don’t love this somewhat incoherent retraction for a paper on coherent states, although luckily the publisher was prompt with telling us a little more about what happened.

On October 2, a 2008 physics paper, “Generation of a superposition of coherent states in a resonant cavity and its nonclassicality and decoherence,” was retracted for “several scientific errors,” pointed out by a comment published in the same journal. The original authors rewrote the paper, but it was not up to the standards of *Canadian Journal of Physics, *so it was rejected, and the original was retracted.

## Is it better to retract a paper, or publish a letter calling the conclusions “unphysical?”

Sometimes publishers and authors decide it’s easier to retract a paper than leave it up for discussion by other scientists.

That seems to be the case here: The authors of a paper in *Langmuir *retracted it in September for a math mistake, but not before the journal refused to publish a comment criticizing the publication.

## Doing the right thing: Particle physicists pull paper after equation collides with the truth

Three physicists at Imperial College London have retracted a paper on Coulomb collisions, a kind of fender bender between two charged particles, after realizing their equations were written wrong.

The mistake resulted in an erroneous conclusion about the strength of the collisions.

## Two-timing sinks papers on ships in journal shaken by major scandal

When we heard about this retraction, we were forced to ask: Are there any articles left in *Journal of Vibration & Control*?

The publication was forced to retract 60 papers by the same author in July, after he was caught exploiting a technological loophole to review his own papers.

Now, papers on loading cargo ships has been felled by a much less tech-savvy method: Two authors submitted a paper to both *Mathematical and Computer Modelling of Dynamical Systems *and the *Journal of Vibration & Control, *both of which accepted and published the paper.

The authors, Yousef M. Al-Sweiti and Dirk Soeffker, have now lost three papers in total. Here’s the joint notice from SAGE and Taylor & Francis (we’ve added links to relevant retractions): Read the rest of this entry »

## Enthusiastic retraction and retracted correction mark loss of researcher’s fourth and fifth papers

Here’s a physics retraction whose use of an exclamation point — the only one we’ve ever seen in a retraction notice! — makes the editors’ exasperation palpable.

It’s also the the fourth retraction for R. K. Singhal, of the University of Rajasthan, Jaipur, India. Behold the notice for “Magnetic behavior of functionally modified spinel Ni0.4Ca0.6Fe2O4 nanoferrite,” in the *International Journal of Modern Physics B*: Read the rest of this entry »

## Hydrogen journal pulls palladium paper for data misuse

The *International Journal of Hydrogen Energy* is retracting a 2013 article for what appears to be the misappropriation of data.

The paper, titled “Hydrogen production by an anaerobic photocatalytic reforming using palladium nanoparticle on boron and nitrogen doped TiO_{2} catalysts,” was written by researchers from the Veltech Dr RR & Dr SR Technical University, in Chennai, India, and Arizona State University.
