Speed test of 'tunneling' electrons challenges alternative interpretation of quantum mechanics
Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, and ability to slip through ...
Real-time simulation makes understanding nonlinear quantum dynamics much easier
Many systems obey simple, linear rules: If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated interactions, that linear rule breaks down into a "nonlinear" ...

Keeping the photon in the dark: A new method for full control of quantum dots
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" excitons emit light and are therefore accessible, dark excitons are optically inactive. As a ...
