• High-resolution imaging captures cavity-induced density waves in a quantum gas

  11 avril
  A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast (…)

• 'Poor man's Majoranas' can be used as quantum spin probes

  11 avril
  A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through collective excitations of the system called quasiparticles.

• Universal surface-growth law confirmed in two dimensions after 40 years

  11 avril
  Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Since then, it has been regarded as a fundamental model in physics, with implications for mathematics, biology, and computer science.

• Scientists turn 'mess' into breakthrough : Chaotic design unlocks next-generation optical devices

  10 avril
  Researchers from the Monash University School of Physics and Astronomy have flipped a long-held assumption in optics, showing that deliberately introducing controlled disorder into ultra-thin optical devices can dramatically increase their power and versatility, without making them bigger or (…)

• Dual-frequency Paul trap shows potential for synthesizing antihydrogen outside of CERN

  10 avril
  A new type of radiofrequency trap can capture particles with extremely different requirements and could theoretically hold both types of particles at the same time. Researchers in the group of Professor Dmitry Budker from the PRISMA++ Cluster of Excellence and the Helmholtz Institute at Johannes (…)
