The Holy Grail of Physics: Superconductivity Without the Cold




A new study reveals that the laws of physics don’t prohibit room-temperature superconductors, rekindling hope for a technological revolution.

Researchers found that fundamental constants determine the upper limit of superconducting temperatures, and luckily, our Universe allows for conditions where this breakthrough might be possible.

The Holy Grail of Physics: Room-Temperature Superconductivity

A new study, published on March 3 in the Journal of Physics: Condensed Matter, suggests that room-temperature superconductivity  long considered the “holy grail” of condensed matter physics  may indeed be possible within the fundamental laws of the universe.

Superconductors, materials that conduct electricity without resistance, have the potential to revolutionize energy transmission, medical imaging, and quantum computing. However, until now, they have only operated at extremely low temperatures, limiting their practical use. The search for a superconductor that functions at everyday temperatures has been one of the most challenging and sought-after goals in modern physics.

Fundamental Constants Set the Limits

In their latest research, Professor Kostya Trachenko of Queen Mary University of London and his colleagues have uncovered a fundamental connection between the maximum possible superconducting temperature (TC) and three universal constants: electron mass, electron charge, and the Planck constant. These constants govern key physical processes, from atomic stability to the formation of stars and essential elements like carbon. Their findings indicate that the theoretical upper limit for superconducting temperatures falls within a range of hundreds to a thousand Kelvin  high enough to include room temperature.

The Dream of Superconductivity Lives On

“This discovery tells us that room-temperature superconductivity is not ruled out by fundamental constants,” said Professor Pickard of University of Cambridge, co-author of this study. “It gives hope to scientists: the dream is still alive.”

The results have already been independently confirmed in a separate study, adding weight to the team’s conclusions. But the implications go even further. By exploring how different values of these fundamental constants could alter the limits of superconductivity, the researchers have opened a fascinating window into the nature of our Universe.

What If the Universe Were Different?

Imagine a world where the fundamental constants are different and set the upper limit for TC at a mere millionth of a Kelvin. In such a Universe, superconductivity would be undetectable, and we would never have discovered it. Conversely, in a Universe where the limit is a million Kelvin, superconductors would be common – even in your electric kettle. “The wire would superconduct instead of heating up,” Professor Trachenko explains. “Boiling water for tea would be a very different challenge.”

It therefore appears that the very reason the community is busy chasing up a room-temperature superconductor is that our fundamental constants set the upper limit of TC in the range 100-1000 K (the range of planetary conditions) where our “room” temperature is.

A Call to Keep Exploring

This research not only advances our understanding of superconductivity but also highlights the delicate balance of the constants that make our Universe – and life within it – possible. For scientists and engineers, this work also provides a renewed sense of direction. “The fact that room-temperature superconductivity is theoretically possible, given our Universe’s constants, is encouraging,” Professors Trachenko and Pickard add. “It’s a call to keep exploring, experimenting, and pushing the boundaries of what’s possible.”

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Freezing light? Italian scientists froze fastest thing in universe, here’s how

In a rare occurrence, physics made it possible to control the fastest travelling element - light. Italian scientists have managed to freeze the light, as per reports. A recent study published in a British weekly journal reportedly revealed that light can exhibit ‘ supersolid behavior ’ a unique state of matter that flows without friction while retaining a solid-like structure. The research, led by Antonio Gianfate from CNR Nanotec and Davide Nigro from the University of Pavia, marks a significant step in understanding supersolidity in light. The scientists described their findings as “just the beginning” of this exploration, as per reports. In what can be termed as ‘manipulating photons under controlled quantum conditions ’, the scientists demonstrated that light, too, can exhibit this behaviour. (A photon is a bundle of electromagnetic energy which is massless, and travel at the speed of light) How did scientists freeze light? As we know, freezing involves lowering a liquid’s tempera...
