Five Incredible Physics Studies Published In 2020

Saying that 2020 has been a difficult year is less to say. Science also had to learn to navigate this brave new world and in the various complexities of this year, we still see progress and advancement in all fields. In physics, we think that these five stories represent some of the best works published in the last 12 months. 

Room-Temperature Superconductivity Has Been Achieved After 109 Years – With A Catch

Superconductivity allows creating a prominent quantum effect that uses magnetic fields as well as the flow of electricity without any resistance. Not every component is superconducting and they need to cool below zero degrees. An element capable of superconducting at room temperature is the long-awaited dream. We have such elements in the end. It superconducts at temperatures of 15°C (59°F) but has a big catch. It only works under extreme pressure. It is to press 2.5 million times the atmospheric pressure at sea level. This can only achieved by shouting between two diamonds very exciting but not surprising material that will change our lives.

Physicists Capture Individual Atoms Merging In World First

This year was also an incredible year for near-term nuclear studies. Researchers were able to capture for the first time how a single molecule formed. The team placed three rubidium atoms in a vacuum chamber with any other atom, and only one fraction of absolute zero. They found that the atoms took longer than expected, possibly due to atomic disintegration. With a large number of atoms, the reaction is more likely to increase, but it can also be due to the system setup. The team is investigating better understand molecular structure.

Researchers Have Finally Measured How Long It Takes For An Atom To Quantum Tunnel

If the laws of quantum mechanics work equally well at the macroscopic level, we will be able to go through them if we often slam in adequate walls (please do not try this at home, you are not an electronic). This strange phenomenon is as quantum tunneling. Put a particle in a box, and there is a chance that it can just pass by and escape. In 2020, physicists are finally working on how long it takes atoms to form a quantum tunnel. One team measured that rubidium atoms exceeded a 1.3 micrometer-thick optical barrier at 0.6 milliseconds. “We’ve known about tunneling for almost a century and we use it in some of the fastest electronics, magnetic devices of the highest accuracy, superconducting quits, etc. The author, Professor Ephraim Steinberg, told IFLScience in July. “Knowing this can help us understand many more related processes where a system can end up in more than one final state, which is ubiquitous in quantum theory.”

First Quantum Entanglement Of Distant Objects Large Enough To See

The most striking feature of quantum mechanics is the lattice. Individual particles become part of a single state, and even within many parts, they respond to instantaneous change. Wrapping is tough to maintain and it mostly confined to a handful of particles. This year, however, scientists were able to create for the first time a quantum entanglement with a system that was large enough to see without a microscope. This is a major step forward in our ability to manage the quantum properties of the system.

Researchers See Tiny Quantum Fluctuations Move A Human-Sized Mirror

The subtle edge of physics is about accuracy and high-quality measurement and it is amazing to see what humanity is capable of doing. An incredible measurement comes from the LGO observes gravitational waves. To capture these tiny changes in the gravitational waves created in space, incredible precision is required for the system. Lasers and mirrors used to identify these minor differences. However, there are other effects on the play; they also need to take into account. It has a quantum effect.
