Quantum undular bores, rainbows, and event horizons in superfluid dam breaks
Liam M. Farrell, Wyatt Kirkby, Alex Harris +3
The sudden removal of a potential barrier from a Bose-Einstein condensate (BEC) gives rise to a quantum version of a hydrodynamic dam break and leads to rich wave dynamics that hav…
A canonical approach to quantum fluctuations
Joanna Ruhl, Vanja Dunjko, Maxim Olshanii
We present a canonical formalism for computing quantum fluctuations of certain discrete degrees of freedom in systems governed by integrable partial differential equations with kno…
Dynamical Fermionization and Emergent Bethe Rapidity Structure in the Spatial Density of Cold quenched Lieb-Liniger gas
Sumita Datta, James M Rejcek, Rajasee Datta +1
We demonstrate that the nonequilibrium spatial density of a one-dimensional interacting Bose gas, following a geometric quench, directly encodes information about the underlying mo…
Thermal fading of the -tail of the momentum distribution induced by the hole anomaly
Giulia De Rosi, Grigori E. Astrakharchik, Maxim Olshanii +1
We study the thermal behavior of correlations in a one-dimensional Bose gas with tunable interaction strength, crossing from weakly-repulsive to Tonks-Girardeau regime. A reference…
Perspective on Quantum Bubbles in Microgravity
Nathan Lundblad, David C. Aveline, Antun Balaz +13
Progress in understanding quantum systems has been driven by the exploration of the geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom Laborator…
Massive particle interferometry with lattice solitons
Piero Naldesi, Juan Polo, Peter D. Drummond +4
We discuss an interferometric scheme employing interference of bright solitons formed as specific bound states of attracting bosons on a lattice. We revisit the proposal of Castin…
Massive particle interferometry with lattice solitons: robustness against ionization
Piero Naldesi, Peter D. Drummond, Vanja Dunjko +2
We revisit the proposal of Castin and Weiss [Phys. Rev. Lett. vol. 102, 010403 (2009)] for using the scattering of a quantum matter-wave soliton on a barrier in order to create a c…
The origin of the period- quasi-breathing in disk-shaped Gross-Pitaevskii breathers
J. Torrents, V. Dunjko, M. Gonchenko +2
We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where…

The recently proposed map [arXiv:2011.01415] between the hydrodynamic equations governing the two-dimensional triangular cold-bosonic breathers [Phys. Rev. X 9, 021035 (2019)] and…
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…

We use the ab initio Bethe Ansatz dynamics to predict the dissociation of one-dimensional cold-atom breathers that are created by a quench from a fundamental soliton. We find that…
