Korean team claims to have created the first room-temperature, ambient-pressure superconductor


A team of physicists in South Korea has announced that they have created a material that can conduct electricity without resistance at room temperature and normal pressure. This would be a major breakthrough in physics and technology, as it could revolutionize the fields of energy, transportation, computing, and medicine.

What is superconductivity and why is it important?

Superconductivity is a phenomenon where certain materials lose all electrical resistance when cooled below a critical temperature. This means that electric currents can flow through them without any loss of energy or generation of heat. Superconductors also have other remarkable properties, such as expelling magnetic fields (the Meissner effect) and forming quantum entanglements with other superconductors (the Josephson effect).

Superconductivity has many potential applications, such as:

  • Super-efficient power transmission and storage
  • High-speed trains that levitate on magnetic tracks
  • Powerful magnets for medical imaging and particle accelerators
  • Quantum computers that can perform complex calculations faster than conventional computers

However, the challenge of superconductivity is that most known superconductors require extremely low temperatures (close to absolute zero) and/or high pressures to achieve this state. This makes them impractical and expensive for widespread use.

How did the Korean team create the room-temperature superconductor?

The Korean team, led by Professor Lee Seung-hoon of Seoul National University, claims to have created a new material that they call LK-99, which can exhibit superconductivity at room temperature (around 20 degrees Celsius) and ambient pressure (around 1 atmosphere). They say they achieved this by mixing two compounds: lanarkite (Pb2SO5) and copper phosphide (Cu3P). They then heated the mixture in a sealed vacuum tube for several hours, which resulted in a dark gray powder.

The team says they tested the electrical and magnetic properties of LK-99 using various methods, such as measuring its resistance, observing its levitation on a magnet, and detecting its quantum tunneling effect. They claim that their results show that LK-99 is indeed a room-temperature, ambient-pressure superconductor.

The team has posted two papers on the arXiv preprint server, where they describe their experiments and findings in detail. They say they have also submitted their papers to peer-reviewed journals for publication.

What are the implications and challenges of this discovery?

If the Korean team’s claim is true, it would be a historic achievement in physics and technology, as it would open up new possibilities for harnessing the power of superconductivity in various domains. It could also lead to new insights into the nature of matter and quantum mechanics.

However, the claim is also met with skepticism and caution by many experts in the field, who point out several issues and questions that need to be addressed before accepting it as valid. Some of these are:

  • The lack of independent verification and replication by other researchers
  • The absence of a clear theoretical explanation for how LK-99 works as a superconductor
  • The inconsistency of some of the data and methods reported by the team
  • The possibility of experimental errors or artifacts that could affect the results
  • The history of false or fraudulent claims of room-temperature superconductivity in the past

Therefore, the Korean team’s claim needs to be scrutinized and tested rigorously by the scientific community before it can be confirmed or refuted. Until then, it remains an intriguing and controversial topic that will attract much attention and debate.

Will we see a new era of superconductivity soon?

The quest for room-temperature, ambient-pressure superconductivity has been one of the holy grails of physics for decades. Many researchers have tried to find or create such materials using various approaches, such as doping, alloying, twisting, or pressurizing different substances. However, none of them have succeeded so far in producing a reliable and reproducible result.

The Korean team’s claim is the latest and most ambitious attempt to achieve this goal. If it turns out to be true, it would be a game-changer for science and technology. If not, it would be another disappointment and setback for the field.

Either way, the search for room-temperature superconductivity will continue, as it offers too much promise and potential to give up on. Perhaps one day, we will witness the dawn of a new era of superconductivity that will transform our world in ways we can hardly imagine.
