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 community needs to reconsider what comprises elementary forces and particles.

Since the early days of general relativity, leading physicists, like Albert Einstein and Erwin Schrödinger, have tried to unify the theory of gravitation and electromagnetism. Many attempts were made during the 20th century, including by Hermann Weyl.

Finally, it seems that we have found a unified framework to accommodate the theory of electricity and magnetism within a purely geometric theory. This means that electromagnetic and gravitational forces are both manifestations of ripples and curvatures in spacetime geometry.

A new study shows that electron spins—tiny magnetic properties of atoms that can store information—can be protected from decohering (losing their quantum state) much more effectively than previously thought, simply by applying low magnetic fields.

Normally, these spins quickly lose coherence when they interact with other particles or absorb certain types of light, which limits their usefulness in technologies like quantum sensors or atomic clocks. But the researchers discovered that even interactions that directly relax or disrupt the spin can be significantly suppressed using weak magnetic fields.

This finding expands our understanding of how to control quantum systems and opens new possibilities for developing more stable and precise quantum devices.

In a groundbreaking experiment, physicists observed a classic liquid phenomenon—capillary instability—in a quantum gas for the first time. By cooling a mix of potassium and rubidium atoms near absolute zero, researchers created tiny self-bound droplets that behave like liquid despite remaining in

Recent physics studies have discovered that quarks and gluons inside protons, which are subatomic positively charged particles, exhibit maximal quantum entanglement at high energies. Entanglement is a physical phenomenon that entails correlations between distant particles that cannot be explained by classical physics theories, resulting in the state of one particle influencing that of another.

Researchers at Stony Brook University and the Brookhaven National Laboratory recently set out to better understand what this recent finding could mean for hadronization, the process by which quarks and gluons form hadrons, which are particles that can be detected experimentally. Their paper, published in Physical Review Letters, introduces a new approach to probe and study hadronization by leveraging quantum entanglement.

“Our study originated from the intriguing observation that the internal structure of protons at high energies exhibits maximal quantum entanglement,” Charles Joseph Naim, corresponding author for the paper, told Phys.org.
