• Driven to succeed : Physicists explore a new way to control quasiparticles

  7 avril
  For the better part of a century, the quantum objects known as quasiparticles have been all dressed up with nowhere to go. But that may change, now that a Yale-led team of physicists has shown it is possible to exert a greater level of control over at least one type of quasiparticle.

• Making the physics of glass more transparent

  7 avril
  For centuries, humans have made use of glass in their art, tools, and technology. Despite the ubiquity of this material, however, many of its microscopic properties are not well understood, and it continues to defy conventional physical description.

• Quantum cosmology with final states can explain the accelerated expansion of the universe

  Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and that it is not compatible with modern science, because it is fundamentally untestable.

• Physicists uncover a metallic altermagnet with d-wave spin splitting at room temperature

  7 avril
  For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails the alignment of electron spins in alternating, opposite directions.

• High-intensity shock tube reveals high-speed interface flow mechanism

  7 avril
  Research teams have established a theoretical method for designing smooth curved wall surfaces with variable cross-section shock tubes, and developed an integrated, high-intensity multifunctional shock tube device. Led by Prof. Luo Xisheng and Prof. Si Ting from the University of Science and (…)
