Abstract

Casimir on the move Two mirrors held parallel to each other in a vacuum experience an attractive force, known as the Casimir effect, which combines aspects of quantum vacuum behaviour with relativity. The force arises when vacuum fluctuations — virtual particles flitting in and out of existence — reduce the radiation pressure between the plates and generate an inward force. The static effect has been well studied, but theory also predicts a dynamical Casimir effect arising from a mismatch of vacuum modes in time rather than space. This paper presents the first observation of this phenomenon in a superconducting circuit.
