The quantum solitons atomtronic interference device
Juan Polo, Piero Naldesi, Anna Minguzzi +1
We study a quantum many-body system of attracting bosons confined in a ring-shaped potential and interrupted by a weak link. With such architecture, the system defines atomtronic q…
A simplified approach to the repulsive Bose gas from low to high densities and its numerical accuracy
Eric A. Carlen, Markus Holzmann, Ian Jauslin +1
In 1963, a Simple Approach was developed to study the ground state energy of an interacting Bose gas. It consists in the derivation of an Equation, which is not based on perturbati…
Probing the BCS-BEC crossover with persistent currents
Giovanni Pecci, Piero Naldesi, Luigi Amico +1
We study the persistent currents of an attractive Fermi gas confined in a tightly-confining ring trap and subjected to an artificial gauge field all through the BCS-BEC crossover.…
Quasi-condensation of bilayer excitons in a periodic potential
Camille Lagoin, Stephan Suffit, Kenneth West +4
We study two-dimensional excitons confined in a lattice potential, for high fillings of the lattice sites. We show that a quasi-condensate is possibly formed for small values of th…
Roadmap on Atomtronics: State of the art and perspective
L. Amico, M. Boshier, G. Birkl +56
Atomtronics deals with matter-wave circuits of ultra-cold atoms manipulated through magnetic or laser-generated guides with different shapes and intensities. In this way, new types…
Universal shock-wave propagation in one-dimensional Bose fluids
Romain Dubessy, Juan Polo, Hélène Perrin +2
We propose a protocol for creating moving, robust dispersive shock waves in interacting one-dimensional Bose fluids. The fluid is prepared in a moving state by phase imprinting and…
