• Trapped photons make strontium titanate ferroelectric
  

  Photons trapped in a cavity can cause a crystal known as strontium titanate (SrTiO₃) to become ferroelectric, according to a new study by the MPSD’s theory group. The photons that are randomly created and destructed in the vacuum of a cavity – as determined by the laws of quantum mechanics – can sig more

• The next phase of the proton puzzle
  

  Scientists at the Max Planck Institute of Quantum Optics (MPQ) have succeeded in testing quantum electrodynamics with unprecedented accuracy to 13 decimal places. The new measurement is almost twice as accurate as all previous hydrogen measurements combined and moves science one step closer to solvi more

• Behind the veil of nothingness
  

  An international research team from Germany and France has created structures in which light fields interact with electrons so strongly that the quantum vacuum itself is significantly altered. Using extremely short bursts of light, they interrupted this coupling much faster than the timescale of a v more

Levitating Nanodiamond Research

Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics. more

• Prediction and understanding of AIE effect by quantum mechanics-aided machine-learning algorithm

  Significant effort has been devoted to the research of aggregation-induced emission (AIE); however, the discovery of new AIE materials is driven mainly by laborious trial-and-error. In this study, taking triphenylamine (TPA)-based luminophores as an example, we propose an efficient machine-learning more
