New Technique Helps Elucidate Role of Phonons in Copper-Based Superconductivity

Since the 1980s, scientists have been well aware of high-temperature superconducting copper-based materials, or cuprates. Below a specific temperature (roughly -130°C), electrical resistance disappears from these materials and magnetic flux fields are released. However, the reason for that superconductivity continues to be discussed and investigated.

Astronomers Spot Unusual Object Unlike Anything Ever Seen Before

While mapping the universe for radio waves, researchers discovered a rare entity that discharges a massive burst of energy three times per hour, and it is unlike anything astronomers have ever observed.

Controlling Quantum-Mechanical Entanglement in Attosecond Pump-Probe Experiments

Quantum mechanics is famous for the way that its predictions challenge intuitive human thinking developed through the way that we experience the everyday world around us. Among other things, quantum objects can display both particle- and wave-like character, can interfere and can occur in the form of quantum superpositions.

Researchers Find Rare Kondo Effect in Transition Metal Oxide

As temperature decreases, so does the electrical resistance of metals -; most of the time. In metal with magnetic impurities, electrical resistance can increase as the temperature drops due to a strange phenomenon called the Kondo effect.

Physicist Proposes a Radical Solution to Century Old Problem of Radiation Reaction

A Lancaster physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field.

Research Reveals Rare Quantum-Like Behavior of Confined Water

Recently, "National Science Review" published online the latest research results of the research team of Professor Zhuhua Zhang and Prof. Wanlin Guo from Institute for Frontier Science, Nanjing University of Aeronautics and Astronautics. The phenomenon of quantum-like Friedel oscillations in one-dimensional confined water was reported.

Creating Matter Directly from Collisions of Light

Nuclear scientists have used a powerful particle accelerator to create matter directly from collisions of light. Scientists predicted this process in the 1930s, but it has never been achieved in a single direct step. The researchers accelerated two beams of gold ions to close to the speed of light in opposite directions.

Energetic Magnons Detected Using Diamond-Based Quantum Sensor

In recent times, sustainable development has been the overarching guiding principle of research concerning environmental issues, energy crises, and information and communication technology. In this regard, spintronic devices have emerged as promising candidates for surpassing conventional technology, which has run into the problem of excess waste heat generation in miniaturized devices.

Vibrating Atoms Make Robust Qubits, Physicists Find

MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states — a weird quantum phenomenon known as superposition.
