Bosonic quantum mixtures with competing interactions: quantum liquid droplets and supersolids
Sarah Hirthe, Leticia Tarruell
These lecture notes contain an introduction to quantum simulation of bosonic systems in the continuum, focusing on weakly interacting Bose-Bose mixtures with competing mean-field i…
Spin-resolved microscopy of Sr SU() Fermi-Hubbard systems
Carlos Gas-Ferrer, Antonio Rubio-Abadal, Sandra Buob +3
Quantum-gas microscopes provide direct access to the phases of the Hubbard model, bringing microscopic insight into the complex competition between interactions, SU(2) magnetism, a…
Encoding a topological gauge theory on a ring-shaped Raman-coupled Bose gas
Claudio Iacovelli, Josep Cabedo, Leticia Tarruell +1
Topological gauge theories constitute a framework for understanding strongly correlated quantum matter in terms of weakly interacting composite degrees of freedom. Their topologica…
Probing supersolidity through excitations in a spin-orbit-coupled Bose-Einstein condensate
C. S. Chisholm, S. Hirthe, V. B. Makhalov +5
Spin-orbit-coupled Bose-Einstein condensates are a flexible experimental platform to engineer synthetic quantum many-body systems. In particular, they host the so-called stripe pha…
Atom-Number Enhancement by Shielding Atoms from Losses in Strontium Magneto-Optical Traps
Jonatan Höschele, Sandra Buob, Antonio Rubio-Abadal +2
We present a scheme to enhance the atom number in magneto-optical traps of strontium atoms operating on the 461 nm transition. This scheme consists of resonantly driving the S$…
Frustrated magnets without geometrical frustration in bosonic flux ladders
Luca Barbiero, Josep Cabedo, Maciej Lewenstein +2
We propose a scheme to realize a frustrated Bose-Hubbard model with ultracold atoms in an optical lattice that comprises the frustrated spin-1/2 quantum XX model. Our approach is b…
