摘要

Abstract

The discovery of artificial gauge fields controlling the dynamics of uncharged particles that otherwise elude the influence of standard electromagnetic fields has revolutionised the field of quantum simulation. Hence

developing new techniques to induce these fields is essential to boost quantum simulation of photonic structures. Here

we experimentally demonstrate the generation of an artificial gauge field in a photonic lattice by modifying the topological charge of a light beam

overcoming the need to modify the geometry along the evolution or impose external fields. In particular

we show that an effective magnetic flux naturally appears when a light beam carrying orbital angular momentum is injected into a waveguide lattice with a diamond chain configuration. To demonstrate the existence of this flux

we measure an effect that derives solely from the presence of a magnetic flux

the Aharonov-Bohm caging effect

which is a localisation phenomenon of wavepackets due to destructive interference. Therefore

we prove the possibility of switching on and off artificial gauge fields just by changing the topological charge of the input state

paving the way to accessing different topological regimes in a single structure

which represents an important step forward for optical quantum simulation.
