ESSAY 13 June 2023 Correction 20 June 2023 Particle, wave, both or neither? The experiment that challenges all we know about reality ...

Holding pattern Small clusters of caesium atoms (pink blobs) were held in a vertical optical lattice. A laser then splits each atom into a quantum state in which half of the atom was closer to a ...

With the atoms cooled and confined, the researchers periodically switched the optical lattice off and on — expanding the atoms from a confined near-particle state to one resembling a wave, and ...

But scientists still have problems conducting matter-wave interferometry on larger molecules because they can easily be broken down into pieces during a measurement. Back in 1999, Arndt and his ...

First proposed by the French physicist Louis de Broglie in 1924 and expanded upon by Erwin Schrödinger two years later, wave particle duality states that all quantum-sized objects, and therefore ...
