Majorana highway on a chip

The first experimental evidence of a Majorana fermion in Delft 2012 led to a wave of scientific enthusiasm: control such particles are a holy grail in quantum science and technology. Quantum chips based on Majorana fermions ...

Neutrons zero in on the elusive magnetic Majorana fermion

Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way for quantum calculations far beyond the limits of ...

Physicists explore elusive high-energy particles in a crystal

Mid-infrared wavelengths of light are invisible to the eye but can be useful for a number of technologies, including night vision, thermal sensing, and environmental monitoring. Now, a new phenomenon in an unconventional ...

Weyl fermions exhibit paradoxical behavior

Theoretical physicists have found Weyl fermions to exhibit paradoxical behavior in contradiction to a 30-year-old fundamental theory of electromagnetism. The discovery has possible applications in spintronics. The study ...

Entropy landscape sheds light on quantum mystery

By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new evidence about the possible ...
