• Rydberg-atom detector conquers a new spectral frontier

  5 décembre
  A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the Center of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum antenna."

• The hexatic phase : Ultra-thin 2D materials in a state between solid and liquid observed for the first time

  5 décembre
  When ice melts into water, it happens quickly, with the transition from solid to liquid being immediate. However, very thin materials do not adhere to these rules. Instead, an unusual state between solid and liquid arises: the hexatic phase. Researchers at the University of Vienna have now (…)

• X-ray spikes reveal electron beam size

  5 décembre
  While synchrotron radiation is often thought of as "stable," the electromagnetic field exhibits pronounced randomly fluctuating distributions both temporally and spatially. These fluctuations encode spatial information about the electron beam that produces the X-rays.

• Shaping quantum light unlocks new possibilities for future technologies

  5 décembre
  Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and time to create high-dimensional and multidimensional quantum states. Their work highlights how (…)

• Probing the existence of a fifth force via neutron star cooling

  5 décembre
  Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into space.
