Why Retraction? New Journal of Physics Investigates

  • Thread starter PFfan01
  • Start date
In summary, the New Journal of Physics has retracted two articles, "Evidence for subwavelength imaging with positive refraction" and "Subwavelength imaging with materials of in-principle arbitrarily low index contrast" due to data shortcuts. The corresponding author, Prof. Ulf Leonhardt, is known for his work on the optics of invisibility objects and suggested the wave-particle duality of light momentum. This is the first retraction for the New Journal of Physics and Prof. Leonhardt has previously served as an Associate Editor for the journal.

According to New Journal of Physics (http://iopscience.iop.org/1367-2630/page/Forthcoming%20articles) :
Retraction: Evidence for subwavelength imaging with positive refraction (2011 <em>New J. Phys</em>. 13 033016) Yun Gui Ma, Sahar Sahebdivan, C K Ong, Tomáˇs Tyc and Ulf Leonhardt
Retraction: Subwavelength imaging with materials of in-principle arbitrarily low index contrast (2012 <em>New J. Phys.</em> 14 025001) Y G Ma, S Sahebdivan, C K Ong, T Tyc and U Leonhardt

The corresponding author, Prof. Ulf Leonhardt, is known for the optics of invisibility objects:
Ulf Leonhardt, Optical Conformal Mapping，Science, Volume 312, Issue 5781, pp. 1777-1780 (2006).
Cited by more than 1400 references, http://adsabs.harvard.edu/abs/2006Sci...312.1777L
Prof. Ulf Leonhardt first suggested the wave-particle duality of light momentum: Uif Leonhardt, "Momentum in an uncertain light," Nature 444 (7121): 823-824(2006).

Not sure. Do journals usually state the reason they retract articles?

Seems this is the first time of retraction for New Journal of Physics, and Prof. Ulf Leonhardt once was Associate Editor of this journal.
 

1. Why do scientific journals publish retractions?

Retractions are published by scientific journals when there is evidence that a published study or paper contains errors, misleading information, or is not valid. This is done to maintain the integrity and credibility of the journal and the scientific community as a whole.

2. What are the common reasons for a retraction?

The most common reasons for a retraction include plagiarism, data fabrication, ethical violations, errors in data analysis, and misleading or incorrect conclusions. In some cases, retractions are also made when the author requests it due to errors or concerns with the study.

3. How can retractions impact the scientific community?

Retractions can have a significant impact on the scientific community. They can damage the reputation and credibility of the authors, as well as the journal and the field of study. They can also lead to wasted time and resources for researchers who may have used the retracted study as a basis for their own work.

4. Who is responsible for determining if a retraction is necessary?

The responsibility for determining if a retraction is necessary lies with the journal's editorial board. They review the evidence and make a decision based on the guidelines and policies of the journal. In some cases, the authors may also request a retraction or the journal may be alerted to potential issues by other researchers.

5. How can readers identify retracted studies?

Most journals will clearly label retracted studies as "retracted" in the title, abstract, and full text of the article. Additionally, the journal's website may have a separate section for retractions or a list of retracted studies. Some databases also have a specific filter for retracted studies. It is important for readers to thoroughly examine the article and its sources before using information from a retracted study.
