• Quantum computer simulates spontaneous symmetry breaking at zero temperature

  2 juillet
  For the first time, an international team of scientists has experimentally simulated spontaneous symmetry breaking (SSB) at zero temperature using a superconducting quantum processor. This achievement, which was accomplished with over 80% fidelity, represents a milestone for quantum computing (…)

• Slithering snakes : The science behind the motion of a young anaconda

  2 juillet
  The motion of snakes has long fascinated humans: they undulate, they sidewind, they crawl, they even fly.

• Shape-shifting particles allow temperature control over fluid flow and stiffness

  2 juillet
  Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago Pritzker School of Molecular Engineering and NYU Tandon have now developed such a material, using tiny (…)

• The hidden mechanics of abrupt transitions : Superconducting networks show how tiny changes trigger system collapse

  2 juillet
  Why do some changes in nature unfold gradually, while others occur in the blink of an eye? Rust forming on metal is a slow, steady process that takes days or even weeks to become visible. By contrast, a power grid can collapse in mere seconds. What accounts for this difference?

• Breaking Ohm's law : Nonlinear currents emerge in symmetry-broken materials

  2 juillet
  In a review just published in Nature Materials, researchers take aim at the oldest principle in electronics: Ohm's law.
