Latest Wave–particle duality Stories
Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times. Taking a radically different experimental approach, EPFL scientists have now been able to take the first ever snapshot of light behaving both as a wave and as a particle.
Says guys who eat, sleep and breathe quantum physics.
For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behavior.
In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory.
The precise methodology of Richard Feynman's famous double-slit thought-experiment – a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave – has been followed in full for the very first time.
Matter wave interferometry has a long standing tradition at the University of Vienna, where the first quantum interference of large molecules has already been observed in 1999.
Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier.
Quantum theory describes the world of atoms very precisely.
The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behavior – in conflict with our everyday ideas of what is real or local.
