• Secrets of superfluid : How dipolar interactions shape two-dimensional superfluid behavior

  17 avril
  In a recent study, researchers made a significant observation of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a 2D dipolar gas of ultracold atoms. This work marks a milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions. The (…)

• Tying light from lasers into stable ’optical knots’

  17 avril
  Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn't sound like a material that can create a knot.

• Smaller, smarter building blocks for future quantum technology

  17 avril
  Scientists at EPFL have made a breakthrough in designing arrays of resonators, the basic components that power quantum technologies. This innovation could create smaller, more precise quantum devices.

• Chirality induces giant charge rectification in a superconductor

  16 avril
  Recent studies have revealed that electrons passing through chiral molecules exhibit significant spin polarization—a phenomenon known as chirality-induced spin selectivity. This effect stems from a nontrivial coupling between electron motion and spin within chiral structures, yet quantifying it (…)

• Multivalley semiconductor enables optical switching in germanium for high-speed computing and communications

  16 avril
  Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a material. Remarkably, when the laser is switched on and off at ultrahigh speeds, the effect can be (…)
