Quantum disoliton as a one-dimensional linear potential system

ORAL

Abstract

Disoliton as a bounded soliton system appeared initially in a swimming pool in the form of half vortex ring. Subsequently, it turns out to be a universal phenomenon at all length scales. Despite the discovery of several disoliton systems, their underlying physics such as nature of an interaction potential remains elusive due to the lack of a model system allowing controllability and repeatability. Here we report on a quantum disoliton (QDS) created as a U-shape quantum flux tube in a superconducting Nb film. A systematic control on a single QDS reveals the purported 1D linear potential, i.e. distance-independent force. The QDS will provide a novel platform for exploring 1D phase transition, quantum transport, and non-Abelian statistics.
