Doubly-excited electrons reach new energy states

Positrons are short-lived subatomic particle with the same mass as electrons and a positive charge. They are used in medicine, e.g. in positron emission tomography (PET), a diagnostic imaging method for metabolic disorders. ...

Nanocrystals emit light by efficiently 'tunneling' electrons

Using advanced fabrication techniques, engineers at the University of California San Diego have built a nanosized device out of silver crystals that can generate light by efficiently "tunneling" electrons through a tiny barrier. ...

New mechanism of radio emission in neutron stars released

Young scientists from ITMO University have explained how neutron stars generate intense directed radio emission. They developed a model based on the transitions of particles between gravitational states, i.e. quantum states ...
