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…
Non-equilibrium diagrammatic approach to strongly interacting photons
Johannes Lang, Darrick E. Chang, Francesco Piazza
We develop a non-equilibrium field-theoretical approach, based on a systematic diagrammatic expansion, for strongly interacting photons in optically dense atomic media. We consider…
Self-bound Bose-Fermi liquids in lower dimensions
Debraj Rakshit, Tomasz Karpiuk, Paweł Zin +3
We study weakly interacting mixtures of ultracold atoms composed of bosonic and fermionic species in 2D and 1D. When interactions between particles are appropriately tuned, self-bo…
Relaxation, chaos, and thermalization in a three-mode model of a BEC
M. A. Garcia-March, S. van Frank, M. Bonneau +3
We study the complex quantum dynamics of a system of many interacting atoms in an elongated anharmonic trap. The system is initially in a Bose-Einstein condensed state, well descri…
Gross-Neveu-Wilson model and correlated symmetry-protected topological phases
A. Bermudez, E. Tirrito, M. Rizzi +2
We show that a Wilson-type discretization of the Gross-Neveu model, a fermionic N-flavor quantum field theory displaying asymptotic freedom and chiral symmetry breaking, can serve…
Using polarons for sub-nK quantum non-demolition thermometry in a Bose-Einstein condensate
Mohammad Mehboudi, Aniello Lampo, Christos Charalambous +3
We introduce a novel minimally-disturbing method for sub-nK thermometry in a Bose-Einstein condensate (BEC). Our technique is based on the Bose-polaron model; namely, an impurity e…
Three-dimensional droplets of swirling superfluids
Yaroslav V. Kartashov, Boris A. Malomed, Leticia Tarruell +1
A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduce…
Topological Time Crystals
K. Giergiel, A. Dauphin, M. Lewenstein +2
By analogy with the formation of space crystals, crystalline structures can also appear in the time domain. While in the case of space crystals we often ask about periodic arrangem…
Effective control of chemical potentials by Rabi coupling with rf-fields in ultracold mixtures
Luca Lepori, Anna Maraga, Alessio Celi +2
We show that a linear term coupling the atoms of an ultracold binary mixture provides a simple method to induce an effective and tunable population imbalance between them. This ter…
Non-Markovian polaron dynamics in a trapped Bose-Einstein condensate
Aniello Lampo, Christos Charalambous, Miguel Ángel García-March +1
We study the dynamics of an impurity embedded in a trapped Bose-Einstein condensate (Bose polaron), by recalling the quantum Brownian motion model. It is crucial that the model con…
Efficient algorithm to compute the second Chern number in four dimensional systems
M. Mochol-Grzelak, A. Dauphin, A. Celi +1
Topological insulators are exotic material that possess conducting surface states protected by the topology of the system. They can be classified in terms of their properties under…
Observation of the topological Anderson insulator in disordered atomic wires
Eric J. Meier, Fangzhao Alex An, Alexandre Dauphin +4
Topology and disorder have deep connections and a rich combined influence on quantum transport. In order to probe these connections, we synthesized one-dimensional chiral symmetric…
Strongly Correlated Bosons on a Dynamical Lattice
Daniel González-Cuadra, Przemysław R. Grzybowski, Alexandre Dauphin +1
We study a one-dimensional system of strongly correlated bosons on a dynamical lattice. To this end, we extend the standard Bose-Hubbard Hamiltonian to include extra degrees of fre…
