Report

Effect of strong confinement on the order parameter dynamics in fermionic superfluids

Autor: Cabrera, Cesar R., Henke, René, Broers, Lukas, Skulte, Jim, Collado, H. P. Ojeda, Biss, Hauke, Mathey, Ludwig, Moritz, Henning

Fermionic pairing and the superfluid order parameter change dramatically in low-dimensional systems such as high-T$_c$ superconductors. Here we show how the order parameter dynamics, which defines essential collective properties, is modified by stron

Report

Frustrated extended Bose-Hubbard model and deconfined quantum critical points with optical lattices at the anti-magic wavelength

Autor: Baldelli, Niccolò, Cabrera, Cesar R., Julià-Farré, Sergi, Aidelsburger, Monika, Barbiero, Luca

Publikováno v: Phys. Rev. Lett. 132, 153401 (2024)

The study of geometrically frustrated many-body quantum systems is of central importance to uncover novel quantum mechanical effects. We design a scheme where ultracold bosons trapped in a one-dimensional state-dependent optical lattice are modeled b

Covariant description of the colloidal dynamics on curved manifolds

Autor: Castro-Villarreal, Pavel, Solano-Cabrera, César O., Castañeda-Priego, Ramón

Brownian motion is a universal characteristic of colloidal particles embedded in a host medium, and it is the fingerprint of molecular transport or diffusion, a generic feature of relevance not only in Physics but also in several branches of Science

Report

An unsupervised deep learning algorithm for single-site reconstruction in quantum gas microscopes

Autor: Impertro, Alexander, Wienand, Julian F., Häfele, Sophie, von Raven, Hendrik, Hubele, Scott, Klostermann, Till, Cabrera, Cesar R., Bloch, Immanuel, Aidelsburger, Monika

Publikováno v: Commun. Phys. 6, 166 (2023)

In quantum gas microscopy experiments, reconstructing the site-resolved lattice occupation with high fidelity is essential for the accurate extraction of physical observables. For short interatomic separations and limited signal-to-noise ratio, this

Realizing a 1D topological gauge theory in an optically dressed BEC

Autor: Frölian, Anika, Chisholm, Craig S., Neri, Elettra, Cabrera, Cesar R., Ramos, Ramón, Celi, Alessio, Tarruell, Leticia

Publikováno v: Nature 608, 293-297 (2022)

Topological gauge theories describe the low-energy properties of certain strongly correlated quantum systems through effective weakly interacting models. A prime example is the Chern-Simons theory of fractional quantum Hall states, where anyonic exci

Anomalous buoyancy of quantum bubbles in immiscible Bose mixtures

Autor: Edler, Daniel, Ardila, L. A. Peña, Cabrera, Cesar R., Santos, Luis

Publikováno v: Physical Review Research 4,033017(2022)

Buoyancy is a well-known effect in immiscible binary Bose-Einstein condensates. Depending on the differential confinement experienced by the two components, a bubble of one component sitting at the center of the other eventually floats to the surface

Report

Fast long-distance transport of cold cesium atoms

Autor: Klostermann, Till, Cabrera, Cesar R., von Raven, Hendrik, Wienand, Julian F., Schweizer, Christian, Bloch, Immanuel, Aidelsburger, Monika

Transporting cold atoms between distant sections of a vacuum system is a central ingredient in many quantum simulation experiments, in particular in setups, where a large optical access and precise control over magnetic fields is needed. In this work
