Yakir Aharonov

1932- · quantum mechanics, quantum field theory, quantum information
Israeli physicist who predicted the Aharonov-Bohm effect, demonstrating the fundamental role of electromagnetic potentials in quantum mechanics even in the absence of fields. This effect has applications in quantum computing.

Biography

Born in Haifa. Studied at the Technion, PhD at the University of Bristol (UK). Worked at the University of South Carolina, then at Tel Aviv and Chapman universities. Member of the US National Academy of Sciences and the Israel Academy of Sciences and Humanities. Recipient of many awards, including the Wolf Prize.

Key discoveries

💡 Initially, colleagues were skeptical of the Aharonov-Bohm effect, but later it was confirmed experimentally and became a classic of quantum physics.
"He believed that quantum mechanics teaches us that reality is richer than we could have imagined without equations."

Dance of the Octopus Electron: What Quantum Tunneling Says About the Nature of Reality
A tiny tungsten tip with a radius of less than a hundred nanometers is the perfect stage for watching a quantum performance. Apply an electric field of a few volts per nanometer, and electrons start flying out of the metal: that’s field emission.

Magnetic field turns the void into a motor
Two metal plates in a perfect vacuum attract each other. Even Richard Feynman compared emptiness to a boiling foam: particle pairs are born and immediately vanish, creating the Casimir effect. If the plates are asymmetric, they also start to twist — that's a vacuum motor. But rotation doesn't require oddly shaped parts.

A Cage of Light: How an Ion Gets Stuck in a Lattice
An ordinary magnet makes a compass needle turn, but it doesn't stop the needle from moving forward. But if you twist a magnetic field into a knot, it can trap a particle in place, like a snare. This phenomenon is called an 'Aharonov–Bohm cage': the particle's waves cancel each other out at some points and reinforce at others, leaving only tiny 'islands' where it can exist.

Magnetic Resonance for Electrons
Electrons in a conductor behave like a crowd on an escalator: each one moves on its own, but together they create a flow. If you make them circle around a ring, their angular momentum (a measure of rotation) can couple to a magnetic field, like gears in a clock.

The Invisible Ocean That Holds the Atom
According to ordinary mechanics, an electron in an atom should spiral into the nucleus and crash into it, like a surfer losing speed and falling off the board. But atoms live for billions of years. Because space isn’t empty. Even in absolute vacuum, an invisible electromagnetic sea ripples — the zero-point field. Its waves continuously nudge the electron.

Echo of the Void: How to Catch the Invisible
A palm hovering over a hot stove feels the heat even when the surrounding air seems cool. Something similar happens to electrons in the Aharonov–Bohm effect: the particle senses an electric voltage even though it enters a region where the field has already been switched off.

Electron and muon magnetic moments search for New Physics
Electrons and muons are tiny magnets. Their magnetism is slightly more than two (in special units), and this 'excess fraction' (anomalous magnetic moment) arises from constant ripples in the vacuum: particle pairs momentarily pop into existence and vanish.

How Magnetic Fields Are Born in a Void
Space is threaded with magnetic fields. They exist around galaxies, stars, and even in nearly empty voids — the vast empty spaces between galaxy clusters. It's usually thought that fields are amplified from weak 'seed' fields by turbulence, much like a dynamo. But the origin of the seed fields themselves has remained a puzzle.

Magnetic Fields from Cosmic Ripples
In the vast clouds of rarefied gas that fill the space between stars, something is always churning. Supernova explosions, colliding streams — all of it shakes the plasma. And in this rippling, as it turns out, hides the mechanism that gives birth to magnetic fields. Plasma is a gas in which electrons are stripped from atoms.

Magnetic Vortex as a Curved Lens for Electrons
A vortex in a magnetic material is like a whirlpool, but instead of water, the directions of magnetization twist. An electron flying through such a vortex feels not just a magnetic field, but a curvature of space: its path bends as if it were rolling down a funnel with a narrow neck.
