South Korean room temperature superconductor team: the paper is defective, released by a member without authorization, and has asked to be removed.

Thanks to CTOnews.com netizens Xiao Zhan cut, Brother Black fly's left hand clue delivery! CTOnews.com, August 2, recently, a South Korean research team published a paper on the preprint website arXiv, claiming that room temperature superconductivity has been realized, which has aroused widespread concern and doubt in the global physical and social circles. However, members of the research team said the paper was flawed and was published by a member of the team without their consent and has now asked the arXiv to withdraw the paper.

Superconductor is a material that can conduct current with zero resistance, which has great application value in science and technology, but the realization of superconducting state usually requires very low temperature and high pressure. If superconductivity can be realized at room temperature and pressure, it will have a great impact on the development of human science and technology. However, this goal has been difficult to achieve, and in the past, several research teams claimed to have achieved room temperature superconductivity, all of which turned out to be fake or wrong.

The South Korean research team says they have found a new material called LK-99 that can exhibit superconductivity below 127C. This material is made of lead apatite with a slightly changed hexagonal structure, introducing a small amount of copper, and they provide some experimental data and images in this paper to support their observations.

However, this paper was quickly questioned and criticized by the international physics community. Some experts pointed out that the data and images in the paper were inconsistent and unreasonable, and did not provide enough details and evidence to prove the superconductivity, and some even suspected that it was a prank or hoax.

According to arXiv, the research team includes Li Shuopei, a representative of the Quantum Energy Research Institute, Quan Yingwan, a research professor at Koryo University, Wu Genhao, an emeritus professor at Hanyang University, and Kim Hyun-joo, a former Korea Institute of Electronic Communications (ETRI).

After the paper attracted international attention, Li Shuopei said in a recent interview with Yonhap news agency that the research team was not ready to publish the paper, but Quan Yingwan released the paper without the consent of other authors, and the team is currently asking arXiv to remove the paper from the shelves.

Li Shuopei also said that the study is actually a supplement to the superconductor papers published in South Korean journals in April this year, and has applied to international journals for review.

Kim Hsien-joo also said in an interview with the US media that the paper still had many defects and was published without his permission.

It is not known why Quan Yingwan published this paper without authorization, and whether he has any other motives or backgrounds. As of the CTOnews.com press release, Quan Yingwan has not made any response or explanation on the matter.
