Shapiro steps in driven atomic Josephson junctions
Vijay Pal Singh, Juan Polo, Ludwig Mathey +1
We study driven atomic Josephson junctions realized by coupling two two-dimensional atomic clouds with a tunneling barrier. By moving the barrier at a constant velocity, dc and ac…
Soliton versus single photon quantum dynamics in arrays of superconducting qubits
Ben Blain, Giampiero Marchegiani, Juan Polo +2
Superconducting circuits constitute a promising platform for future implementation of quantum processors and simulators. Arrays of capacitively coupled transmon qubits naturally im…
Exact one-particle density matrix for SU() fermionic matter-waves in the strong repulsive limit
Andreas Osterloh, Juan Polo, Wayne J. Chetcuti +1
We consider a gas of repulsive -component fermions confined in a ring-shaped potential, subject to an effective magnetic field. For large repulsion strengths, we work out a Beth…
Interference dynamics of matter-waves of SU() fermions
Wayne J. Chetcuti, Andreas Osterloh, Luigi Amico +1
We analyze the two main physical observables related to the momenta of strongly correlated SU() fermions in ring-shaped lattices pierced by an effective magnetic flux: homodyne…
Coherent phase slips in coupled matter-wave circuits
Axel Pérez-Obiol, Juan Polo, Luigi Amico
Quantum Phase slips are dual process of particle tunneling in coherent networks. Besides to be of central interest for condensed matter physics, quantum phase slips are resources t…
Formation of local and global currents in a toroidal Bose--Einstein condensate via an inhomogeneous artificial gauge field
S. Sahar S. Hejazi, Juan Polo, Makoto Tsubota
We study the effects of a position-dependent artificial gauge field on an atomic Bose--Einstein condensate in quasi-one-dimensional and two-dimensional ring settings. The inhomogen…

Muhammad S. Hasan, J. Polo, J. C. Pelayo +1
We show that the motion of an accelerated atomic impurity immersed in a spin-orbit coupled Bose-Einstein condensate in the supersolid stripe phase undergoes oscillations, similar t…
Deep learning based quantum vortex detection in atomic Bose-Einstein condensates
Friederike Metz, Juan Polo, Natalya Weber +1
Quantum vortices naturally emerge in rotating Bose-Einstein condensates (BECs) and, similarly to their classical counterparts, allow the study of a range of interesting out-of-equi…

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…
Symmetry breaking in binary Bose-Einstein condensates in the presence of an inhomogeneous artificial gauge field
S. Sahar S. Hejazi, Juan Polo, Rashi Sachdeva +1
We study a two component Bose-Einstein condensate in the presence of an inhomogeneous artificial gauge field. In response to this field, the condensate forms a localised vortex lat…

Axel Pérez-Obiol, Juan Polo, Taksu Cheon
We consider attractive and repulsive condensates in a ring trap stirred by a weak link, and analyze the spectrum of solitonic trains dragged by the link, by means of analytical exp…

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…
