Publikováno v: Physical Review A. 107

We study a system of a few ultracold bosons loaded into the states with orbital angular momentum $l=1$ of a one-dimensional staggered lattice of rings. Local eigenstates with winding numbers $+l$ and $-l$ form a Creutz ladder with a real dimension an

Local Hilbert space fragmentation and weak thermalization in Bose-Hubbard diamond necklaces

Autor: Eulàlia Nicolau, Anselmo M. Marques, Jordi Mompart, Verònica Ahufinger, Ricardo G. Dias

We study Bose-Hubbard models in a family of diamond necklace lattices with $n$ central sites. The single-particle spectrum of these models presents compact localized states (CLSs) that occupy the up and down sites of each diamond. By performing an ap

We propose the Subwavelength Localization via Adiabatic Passage (SLAP) technique to coherently achieve state-selective patterning of matter waves well beyond the diffraction limit. The SLAP technique consists in coupling two partially overlapping and

Coherent control of regions with spatial excitation of populations and coherence between two lower states in three-level $\ensuremath{\Lambda}$-type quantum systems mediated by the self-induced transparency (SIT) phenomenon is theoretically investiga

Effective triangular ladders with staggered flux from spin-orbit coupling in 1D optical lattices

Publikováno v: The European Physical Journal D. 74

Light-induced spin-orbit coupling is a flexible tool to study quantum magnetism with ultracold atoms. In this work we show that spin-orbit coupled Bose gases in a one-dimensional optical lattice can be mapped into a two-leg triangular ladder with sta
