SUMMARY:ICFO | DANIEL GONZÁLEZ CUADRA
CLASS:PUBLIC
DESCRIPTION:The outstanding progress achieved in the last decades to isolat
 e and manipulate individual quantum systems has revolutionized the way in 
 which quantum many-body phenomena\, appearing across Nature's different en
 ergy scales\, can be investigated. By employing atomic systems such as ult
 racold atoms in optical lattices\, an enormous range of paradigmatic model
 s from condensed-matter and high-energy physics are being currently studie
 d using table-top experiments\, turning Feynman's idea of a quantum simula
 tor into a reality.Quantum simulators offer the possibility to gather info
 rmation about complex quantum systems\, which are either not accessible to
  experiments or whose properties can not be easily derived using standard 
 analytical or numerical approaches. These synthetic quantum systems can be
  designed precisely such that they are described under the same models as 
 natural systems\, and their remarkable control allows to probe the relevan
 t phenomena associated to them. Apart from their quantum simulation capabi
 lities\, atomic systems can also be employed to generate quantum matter wi
 th novel properties beyond those found in Nature\, offering interesting pr
 ospects for quantum technological applications. In this thesis\, we invest
 igate the possibilities that cold-atom systems present to address\, in par
 ticular\, quantum matter with non-trivial topological properties. Using mi
 xtures of ultracold atoms\, we analyze various quantum simulation strategi
 es to access several many-body phenomena for which a satisfactory understa
 nding is still lacking. Moreover\, we show how such platforms display stro
 ngly-correlated topological effects beyond those found in natural systems.
  We first focus on models inspired by condensed-matter physics. More preci
 sely\, we propose how lattices dynamics\, similar to those described by ph
 onons in solid crystals\, can be implemented in an otherwise static optica
 l lattice. By coupling the former to quantum matter using a mixture of bos
 onic atoms\, we reproduce typical effects described by electronic systems\
 , such as topological defects or charge fractionalization. We then extend 
 these results and find novel features\, from boson fractionalization to in
 tertwined topological phases.We then consider the quantum simulation of hi
 gh-energy-physics problems. By using Bose-Fermi mixtures\, we show how non
 -perturbative phenomena characteristic of non-abelian gauge theories\, suc
 h as quark confinement\, emerge in simpler models that are within the reac
 h of current technology. Finally\, we investigate how the interplay betwee
 n gauge invariance and strong correlations gives rise to various mechanism
 s to prepare robust topological order in near-term quantum simulators.In s
 ummary\, our results show several connections between different areas of t
 heoretical and experimental physics\, and indicate how these can be harnes
 sed further to advance our understanding of strongly-correlated quantum ma
 tter\, as well as to utilize the latter for new technological applications
