Quantum Light’s Perception of Quantum Sound

Credit: azoquantum.comResearchers at the University of East Anglia have proposed a novel method for using quantum light to observe quantum sound. Their recent publication explores the quantum interaction between light particles (photons) and molecular vibrations. This discovery could deepen our understanding of molecular-level light-matter interactions and their relevance in applications, from quantum technologies to...

Revealing the Remarkable Properties of Multilayer Graphene

Graphene, a material derived from ordinary pencil lead when shaved down to atomic layers, has demonstrated an array of extraordinary properties over the years. When stacked into five layers in a rhombohedral pattern, graphene exhibits a rare "multiferroic" state, combining unconventional magnetism and a unique form of electronic behavior known as ferro-valleytricity. This discovery,...

A revolutionary Discovery About Accelerating Quantum Entanglement

Hohenberg Professor of PhysicsWeijian Chen, a postdoctoral research...

Unraveling the Mystery of Insulator-to-Metal Transitions: A Quantum Avalanche Study

Credit: Unsplash.Most materials can be classified into two categories based on their subatomic particles: metals and insulators. Like copper and iron, metals possess free-flowing electrons that enable them to conduct electricity, while insulators, such as glass and rubber, tightly bind their electrons, making them non-conductive.The intriguing aspect of insulators is that they can be...

Using Gravitational Waves to Hunt for Dark Matter

Credit: Unsplash.A global team of cosmologists has discovered through computer simulations that observing gravitational waves from merging black holes can reveal the real nature of dark matter. Dr. Alex Jenkins of University College London will co-author their discovery today at the 2023 National Astronomy Meeting.The team studied the production of gravitational wave signals in...

Researchers Devise a Current Path Toward ‘Quantum Light’

Credit: CC0 Public DomainA team of scientists from the University of Cambridge, along with researchers from the United States, Israel, and Austria, have developed a theory that could generate high-energy "quantum light" to study new properties of matter at the atomic level.They have reported their findings in the journal Nature Physics. While classic...

First Observation of the Cherenkov Radiation Phenomenon in a 2D Space

A single free electron propagates above the special layered structure that the researchers engineered, only a few tens of nanometers above it.During its movement, the electron emits discrete packets of radiation called "photons". Between the electron and the photons it emitted, a connection of "quantum entanglement" is formed. Credit: Ella Maru StudioResearchers from the...

Research Uncovers Existing Limitations in The Detection of Entanglement

An intuitive illustration of our theorem. Assume the state we consider has dimension d and is coupled with an environment with dimension k. We use three balls to represent the states, whereas the outer one contains all the states.Quantum entanglementQuantum entanglement is a process through which 2 particles become entangled and remain linked...

A Peculiar Protected Structure Links Viking knots With Quantum Vortices

In Borromean rings, each circle holds the pattern together by passing through the other two circles. Credit: Alexandr Kakinen / Aalto UniversityResearchers have demonstrated how three vortices can be linked to prevent them from being dismantled. The structure of the links resembles a pattern used by Vikings and other old cultures. However, this research...
