Atomtronics1, 2 is an emerging interdisciplinary field that seeks to develop new functional methods by creating devices and circuits where ultracold atoms, often superfluids, have a role analogous to that of electrons in electronics. Hysteresis is widely used in electronic circuits—it is routinely observed in superconducting circuits3 and is essential in radio-frequency superconducting quantum interference devices4. Furthermore, it is as fundamental to superfluidity5 …. “}}
