Study shows that duality operators can be realized as unitary linear-depth quantum circuits

In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been aimed at understanding and ...

Einstein's dream of a unified field theory accomplished?

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the view that the scientific ...

Theoretical physicists unveil 'supermazes' to decode black-hole microstructure

A team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their detailed structure, as shown in a research study recently published in Journal of High Energy Âé¶¹ÒùÔºics.

Ultralight dark matter could explain early black hole formation

A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. There are two main types of black hole; stellar mass and supermassive black holes, and they differ in size, formation, ...

Dirac's Plate Trick, the Hairy Ball Theorem and more: Research probes physics of irregular objects on inclined planes

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon. But the world is messier than a textbook.

Quantum entanglement sensors could test quantum gravity

Ask almost any physicist what the most frustrating problem is in modern-day physics, and they will likely say the discrepancy between general relativity and quantum mechanics. That discrepancy has been a thorn in the side ...

Distinguishing classical from quantum gravity through measurable stochastic fluctuations

In a new Âé¶¹ÒùÔºical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature.

What's the shape of the universe? Mathematicians use topology to study its shape and everything in it

When you look at your surrounding environment, it might seem like you're living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents all the places around ...

Âé¶¹ÒùÔºicists measure a key aspect of superconductivity in 'magic-angle' graphene

Superconducting materials are similar to the carpool lane in a congested interstate. Like commuters who ride together, electrons that pair up can bypass the regular traffic, moving through the material with zero friction.

Research identifies migration, housing quality as risk factors in earthquake deaths

The vast majority of earthquakes strike inside the Ring of Fire, a string of volcanoes and tectonic activity that wraps around the coastlines of the Pacific Ocean. But when an earthquake hits, the areas that experience the ...
