What is Demon particle, which existence is confirmed by physicist?

Researchers at the University of Illinois have discovered a Demon Particle that could lead to the making of superconductors that can operate at room temperature.

About:

It was first predicted by theoretical physicist David Pines in 1956.
Pines theorised that electrons passing through a solid would exhibit unique behaviours and that these behaviours could lead to the formation of a new type of particle that he called a “demon particle.”
They are massless, chargeless, and transparent to light.
They are also able to form plasmons, which are collective units of electrons that behave like waves.
Plasmons are important in superconductivity, and the discovery of demon particles could lead to the development of new superconducting materials that operate at room temperature.

Why it is named a ‘Demon’ particle?

This name was chosen because the particle’s properties, including being massless, charge less, and not interacting with light, seemed to defy conventional understanding, much like a mythical or supernatural entity. The term “demon” was used metaphorically to convey the unusual and counterintuitive nature of this theoretical particle.

What is the significance of this discovery?

Superconductors, which can conduct electricity without resistance, currently require extremely low temperatures, often below 100 degrees Fahrenheit.

This discovery of the Demon Particle could lead to the making of superconductors that can operate at room temperature.

Meissner-Ochsenfeld Effect:

Superconductors expel magnetic fields from their interior when they enter the superconducting state.
This effect, known as the Meissner-Ochsenfeld effect, causes the superconductor to repel magnetic fields, leading to the phenomenon of magnetic levitation.
When a magnet is brought near a superconductor in its superconducting state, it will float above the superconductor due to this repulsion.

Why is understanding the behavior of the ‘demon particle’ challenging?

The electrically neutral nature of the ‘demon particle’ makes it distinct from particles that interact with light. This uniqueness requires researchers to employ unconventional experimental approaches to comprehend its behavior fully.
