For the past eight years, two French researchers have been bouncing droplets around a vibrating oil bath and observing their unique behavior. What sounds like a high-school experiment has in fact provided the first ever evidence that the strange features of the quantum world can be reproduced on a macroscopic scale. Now, many researchers are asking if the oil-bath experiments can provide insights into quantum mechanics and more specifically why particles can behave as waves and waves can...

MIT researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle duality 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. According to de Broglie, moving particles — such as electrons, or the photons in a beam of light — are borne along on...

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. Although the particle-wave duality of electrons has been demonstrated in a number of different ways since Feynman popularized the idea in 1965, none of the experiments have managed to fully replicate the methodology set out in Volume 3 of...

Wave Properties of Individual Heavy Molecules Can Also Be Observed Experimentally/Video Shows Development of Interference Pattern in (Nearly) Real Time Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of everyday´s world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, an international team of researchers has...

Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it? An international team of researchers, led by University of Toronto physicist Aephraim Steinberg of the Centre for Quantum Information and Quantum Control, have found a way to do just...

A hundred years ago, we took the first steps in recognising, at the level of elementary physical events, the dual character of nature that had been postulated in natural philosophy. Albert Einstein was the first who saw Max Planck's quantum hypothesis leading to this dual character. Einstein suggested the photon have an electromagnetic wave character, although photons had previously been considered as particles. That was the quintessence of his work on the photoelectric effect. Later in...
