Geometric filtering effect in expanding Bose-Einstein condensate shells
Andrea Tononi, Maciej Lewenstein, Luis Santos
A shell-shaped Bose-Einstein condensate released from its confinement expands radially both outwards and inwards, displaying a self-interference pattern characterized by a density…
Topological bound states in a lattice of rings with nearest-neighbour interactions
Yunjia Zhai, Ayaka Usui, Anselmo M. Marques +2
We study interaction-induced bound states in a system of ultracold bosons loaded into the states with orbital angular momentum in a one-dimensional staggered lattice of rings. We c…
Dimer problem on a spherical surface
A. Tononi, D. S. Petrov, M. Lewenstein
We solve the problem of a dimer moving on a spherical surface and find that its binding energy and wave function are sensitive to the total angular momentum. The dimer gets squeeze…
Interacting bosonic flux ladders with a synthetic dimension: Ground-state phases and quantum quench dynamics
Maximilian Buser, Claudius Hubig, Ulrich Schollwöck +2
Flux ladders constitute the minimal setup enabling a systematic understanding of the rich physics of interacting particles subjected simultaneously to strong magnetic fields and a…
Self-Trapped Polarons and Topological Defects in a Topological Mott Insulator
Sergi Julià-Farré, Markus Müller, Maciej Lewenstein +1
Many-body interactions in topological quantum systems can give rise to new phases of matter, which simultaneously exhibit both rich spatial features and topological properties. In…
Mobile impurity in a Bose-Einstein condensate and the orthogonality catastrophe
Nils-Eric Guenther, Richard Schmidt, Georg M. Bruun +2
We analyze the properties of an impurity in a dilute Bose-Einstein condensate (BEC). First the quasiparticle residue of a static impurity in an ideal BEC is shown to vanish with in…
Dynamical solitons and boson fractionalization in cold-atom topological insulators
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
We study the Bose-Hubbard model at incommensurate densities, which describes a one-dimensional system of interacting bosons whose tunneling is dressed by a dynamical…
Quantum droplets of bosonic mixtures in a one-dimensional optical lattice
Ivan Morera, Grigori E. Astrakharchik, Artur Polls +1
We demonstrate the existence of quantum droplets in two-component one-dimensional Bose-Hubbard chains. The droplets exist for any strength of repulsive intra-species interactions p…
Detecting topology through dynamics in interacting fermionic wires
Andreas Haller, Pietro Massignan, Matteo Rizzi
We describe a protocol to read out the topological invariant of interacting 1D chiral models, based on measuring the mean chiral displacement of time-evolving bulk excitations. We…
Interaction control and bright solitons in coherently-coupled Bose-Einstein condensates
J. Sanz, A. Frölian, C. S. Chisholm +2
We demonstrate fast control of the interatomic interactions in a Bose-Einstein condensate by coherently coupling two atomic states with intra- and inter-state scattering lengths of…
Simulating twistronics without a twist
Tymoteusz Salamon, Alessio Celi, Ravindra W. Chhajlany +4
Rotational misalignment or twisting of two mono-layers of graphene strongly influences its electronic properties. Structurally, twisting leads to large periodic supercell structure…
Superfluid vortex dynamics on a torus and other toroidal surfaces of revolution
Nils-Eric Guenther, Pietro Massignan, Alexander L. Fetter
The superfluid flow velocity is proportional to the gradient of the phase of the superfluid order parameter, leading to the quantization of circulation around a vortex core. In thi…
solitons in intertwined topological phases
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +2
Topological phases of matter can support fractionalized quasi-particles localized at topological defects. The current understanding of these exotic excitations, based on the celebr…
Bose-Hubbard physics in synthetic dimensions from interaction Trotterization
L. Barbiero, L. Chomaz, S. Nascimbene +1
Activating transitions between a set of atomic internal states has emerged as an elegant scheme by which lattice models can be designed in ultracold atomic gases. In this approach,…
Entanglement entropy in low-energy field theories at finite chemical potential
Ivan Morera, Irénée Frérot, Artur Polls +1
We investigate the leading area-law contribution to entanglement entropy in a system described by a general Lagrangian with O(2) symmetry containing first- and second-order time de…
Heat current control in trapped BEC
Christos Charalambous, Miguel-Angel Garcia-March, Mohammad Mehboudi +1
We investigate the heat transport and the control of heat current among two spatially separated trapped Bose-Einstein Condensates (BEC), each of them at a different temperature. To…
Beyond-Luttinger-Liquid thermodynamics of a one-dimensional contact repulsive Bose gas
Giulia De Rosi, Pietro Massignan, Maciej Lewenstein +1
We present a thorough study of the thermodynamics of a one-dimensional repulsive Bose gas, focusing in particular on corrections beyond the Luttinger-liquid description. We compute…

Tomasz Sowiński, Miguel Ángel García-March
Recent theoretical and experimental progress on studying one-dimensional systems of bosonic, fermionic, and Bose-Fermi mixtures of a few ultracold atoms confined in traps is review…
Symmetry-Breaking Topological Insulators in the Bose-Hubbard Model
Daniel González-Cuadra, Alexandre Dauphin, Przemysław R. Grzybowski +3
In this work, we study a one-dimensional model of interacting bosons coupled to a dynamical field, the Bose-Hubbard model, and analyze the interplay b…
Interaction-induced transparency for strong-coupling polaritons
Johannes Lang, Darrick E. Chang, Francesco Piazza
The propagation of light in strongly coupled atomic media takes place through the formation of polaritons - hybrid quasi-particles resulting from a superposition of an atomic and a…
Feshbach resonances in potassium Bose-Bose mixtures
L. Tanzi, C. R. Cabrera, J. Sanz +3
We present a detailed study of the scattering properties of ultracold mixtures of bosonic potassium atoms. We locate 20 previously unobserved Feshbach resonances in isotopic 39K-41…
