Poignancy in physics: Retraction for “fatal error” that couldn’t be patched

with one comment

prl-bannerIn August of last year, Mladen Pavičić, chair of physics at the University of Zagreb’s Faculty of Civil Engineering, published a paper in Physical Review Letters on quantum teleportation, “Near-Deterministic Discrimination of All Bell States with Linear Optics.”

Just six days later, after hearing from a physicist in China, Pavičić — who is also affiliated with Harvard’s physics department — submitted a correction, which ran on the journal’s site in November. The correction begins: Read the rest of this entry »

Pair of graphene papers retracted

with 8 comments

Graphene has been hot for several years. Here’s what the Royal Swedish Academy of Sciences had to say about it in 2010 when awarding two researchers the Nobel Prize in Physics for their work:

Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm. Read the rest of this entry »

A quick Physical Review Letters retraction after author realizes analysis was “performed incorrectly”

with 3 comments

One of the authors of a paper in Physical Review Letters has withdrawn it, after someone pointed out an error.

The paper, “Coulomb Forces on DNA Polymers in Charged Fluidic Nanoslits,” was written by Brown University’s Derek Stein and one of his graduate students, Yongqiang Ren. It was published in February of this year, and the retraction ran on July 20.

The notice is forthright: Read the rest of this entry »
