Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

The control over the geometry and topology of quantum systems is crucial for advancing
novel quantum technologies. This work provides a synthesis of recent insights into the …

We study the time evolution of a supercurrent imprinted on a one-dimensional ring of
interacting bosons in the presence of a defect created by a localized barrier. Depending on …

Ring-shaped superfluids with weak links provide a perfect environment for studying
persistent currents and dynamic stirring protocols. Here, we investigate the effects of a weak …

Persistent currents flowing in spatially closed tracks define one of the most iconic concepts
in mesoscopic physics. They have been studied in solid-state platforms such as superfluids …

Motivated by a recent experiment [KC Wright, Phys. Rev. Lett. 110, 025302 (2013) PRLTAO
0031-9007 10.1103/PhysRevLett. 110.025302], we investigate deterministic discontinuous …

We analyze the nucleation of persistent currents in Bose-Einstein condensates of ultracold
gases confined in a ring. This phenomenon has been recently investigated in an experiment …

We demonstrate how a toroidal Bose–Einstein condensate with a movable barrier can be
used to realize an atomtronic SQUID. The magnitude of the barrier height, which creates the …

The fundamental dynamics of ultracold atomtronic devices are reflected in their phonon
modes of excitation. We probe such a spectrum by applying a harmonically driven potential …

Coupled coaxially stacked toroidal condensates with persistent currents suggest an
appealing physical platform for investigation of various phenomena related to interacting …
