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 temperature until it becomes solid.

In this experiment, the researchers reportedly took a different approach, creating a supersolid state in light using advanced quantum techniques.

They worked with a semiconductor platform where photons, the fundamental particles of light, behaved similarly to electrons.

Using a gallium arsenide (used in various applications like lasers, LEDs, and high-speed electronics) structure with microscopic ridges, they fired a laser to produce hybrid light-matter particles known as polaritons, as per reports.

As the photon count increased, a pattern known as satellite condensates emerged. These condensates possessed the same energy but opposite wavenumbers, creating a distinctive spatial structure a defining feature of supersolidity.

In future, according to reports, this can help in more stable quantum bits which would in turn help the field of quantum computing.

According to researchers, quantum effects emerge at temperatures near absolute zero.

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...

Green comet to pass Earth, won't be back for another 50,000 years

   visit:  https://hep-conferences.sciencefather.com/ After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1.   A newly discovered comet could be visible to the naked eye as it shoots past Earth and the Sun in the coming weeks for the first time in 50,000 years, astronomers have said. The comet is called C/2022 E3 (ZTF) after the Zwicky Transient Facility, which first spotted it passing Jupiter in March last year. After travelling from the icy reaches of our Solar System it will come closest to the Sun on January 12 and pass nearest to Earth on February 1. It will be easy to spot with a good pair of binoculars and likely even with the naked eye, provided the sky is not too illuminated by city lights or the Moon. The comet "will be brightest when it is closest to the Earth", Thomas Prince, a physics professor at the California Institute of Technology who works at the Zwicky Transi...

"Explore the Fourth Dimension"

Fourth Dimension   The fourth dimension is a fascinating concept that has captured the imaginations of scientists, mathematicians, and artists for centuries. Unlike our three-dimensional world, which is limited by the linear flow of time, the fourth dimension is a realm of space and time that exists beyond our everyday experience. One way to visualize the fourth dimension is through the use of a hypercube, also known as a tesseract. A hypercube is a cube within a cube, with additional lines and edges connecting the vertices of the two cubes. It's impossible to construct in our three-dimensional world, but it provides a glimpse into what the fourth dimension might look like. Another way to understand the fourth dimension is through the concept of a wormhole, a theoretical passage through space-time that connects two distant points in the universe. A wormhole is like a shortcut through the fabric of space-time, allowing us to travel vast distances in an instant. While there is no de...
