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

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 ...

Atomic distortions reveal new clues about superconductivity

A team of researchers has identified atomic distortions that may be linked with high-temperature superconductivity in a promising class of nickel-based materials, offering new insight into how next-generation superconductors ...

Boron arsenide semiconductor sets record in quantum vibrations

You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a ...

First quantum oscillations observed in gallium nitride holes

Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property ...
