Physicists are rewriting a quantum rule that conflicts with our universe

“There are certain configurations of the future that don’t match anything from the past,” Cotler said. “There is nothing in the past that could evolve in them.” Giddings proposed a similar principle for ruling out the paradoxical states he encountered while studying black holes last year. He calls it “history matters”, and he argues that …

Physicists create the first two-dimensional ferrimagnetism in graphene

Graphic diagram illustrating the Hall effect in the studied system. 1 credit: SPbU Scientists from St. Petersburg University and their foreign colleagues created the world’s first two-dimensional ferromagnetism in graphene. The use of the magnetic state obtained from graphene can become the basis of a new approach to electronics, increasing its energy efficiency and speed …

Unexpected findings in the ‘small’ Big Bang experiment leave physicists perplexed

Scientists conducted ultra-hot experiments at the Relativistic Heavy Ion Collider, recreating temperatures not seen since the Big Bang. The unexpected results stunned physicists. A temperature not seen since the first microsecond of the birth of the universe has been recreated by scientists, and they have discovered that the event did not play out quite as …

No, physicists haven’t made a real wormhole. What they did was pretty cool though

Enlarge / Artist’s illustration of a quantum experiment that studies the physics of traversable wormholes. Wormholes are a classic science fiction trope in popular media, if only because they provide such a handy futuristic plot device for avoiding the problem of relativity violation with longer travel. fast as light. In reality, they are purely theoretical. …

Have physicists created a wormhole in a quantum computer?

An artistic representation of the quantum teleportation experiment. Physicists used a quantum computer to perform a new kind of quantum teleportation, the ability of quantum states to be transported between distant places, as if information could travel instantaneously. Although teleportation is an established technique in quantum technology, the purpose of the latest experiment was to …

Physicists produce symmetry-protected Majorana edge modes on a quantum computer

Artistic representation of Majorana edge modes on a string of superconducting qubits. Credit: Google Quantum AI Google Quantum AI physicists have used their quantum computer to study an efficient type of particle that is more resilient to environmental disturbances that can degrade quantum computations. These effective particles, known as Majorana edge modes, form as a …

Cosmic chocolate pralines: surprising discovery of physicists on the structure of neutron stars

Studying the speed of sound has revealed that heavy neutron stars have a hard mantle and a soft core, while light neutron stars have a soft mantle and a hard core – much like different chocolate pralines. Credit: Peter Kiefer and Luciano Rezzolla Physicists are modeling more than a million equations of state to uncover …
