• Title: Lieb-Robinson bounds and growth of correlations in Bose mixtures
• Authors: Alessandro Michelangeli and Nicola Santamaria
• Abstract summary: For a mixture of interacting Bose gases initially prepared in a regime of condensation (uncorrelation) it is proved that in the course of the time evolution observables of disjoint sets of particles of each species have correlation functions that remainally small in the total number of particles and display a controlled growth in time.

• Abstract: For a mixture of interacting Bose gases initially prepared in a regime of condensation (uncorrelation), it is proved that in the course of the the time evolution observables of disjoint sets of particles of each species have correlation functions that remain asymptotically small in the total number of particles and display a controlled growth in time. This is obtained by means of ad hoc estimates of Lieb-Robinson type on the propagation of the interaction, established here for the multi-component Bose mixture.

• Insulator phases of Bose-Fermi mixtures induced by intraspecies next-neighbor interactions [0.0]
  We study a one-dimensional mixture of two-color fermions and scalar bosons at the hardcore limit. We observed that the non-local interaction could favor or harm the well-known mixed Mott and spin-selective Mott insulators. Our results can inspire or contribute to understanding experiments in cold-atom setups with long-range interactions or recent reports involving quasiparticles in semiconductor heterostructures.

  Two-component mass-imbalanced few-fermion systems confined in a harmonic trap are studied. The role of mass imbalance and particle number imbalance on the system's evolution stability is investigated. The results may have implications for upcoming experiments on fermionic mixtures with a well-defined and small number of particles.

  Two-component mixtures of fermionic particles confined in a one-dimensional harmonic trap are investigated. Specific non-classical pairing correlations are analyzed in terms of the noise correlations. It is shown that along with increasing temperature, any imbalanced system hosting Fulde-Ferrel-Larkin-Ovchinnikov pairs crossovers to a standard Bardeen-Cooper-Schrieffer one characterized by zero net momentum of resulting pairs.

  Lieb-Robinson and related bounds set an upper limit on the rate of spreading of information in non-relativistic quantum systems. We use a recently developed two particle irreducible (2PI) strong coupling approach to out-of-equilibrium dynamics in the Bose-Hubbard model. Our results establish the 2PI strong coupling approach as a powerful tool to study out-of-equilibrium dynamics in the Bose-Hubbard model in dimensions greater than one.
