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 …

Atomtronics is an emerging field that aims to manipulate ultracold atom moving in matter-
wave circuits for fundamental studies in both quantum science and technological …

Superposition states of circular currents of exciton-polaritons mimic the superconducting flux
qubits. The phase of a polariton fluid must change by an integer number of 2 π when going …

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 …

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 …

We present numerical simulations of the cavity optomechanical detection of persistent
currents and bright solitons in an atomic Bose-Einstein condensate confined in a ring trap …

Vorticity in closed quantum fluid circuits is known to arise in the form of persistent currents. In
this work, we develop a method to engineer transport of the quantized vorticity between …

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

We investigate the effects of ellipticity-induced curvature on atomic Bose–Einstein
condensates confined in quasi-one-dimensional closed-loop waveguides. Our theoretical …

Quenching an ultracold bosonic gas in a ring across the Bose–Einstein condensation phase
transition is known, and has been experimentally observed, to lead to the spontaneous …
