Bosonic orbital Su-Schrieffer-Heeger model in a lattice of rings
Eloi Nicolau, Anselmo M. Marques, Jordi Mompart +2
We study the topological properties of interacting and non-interacting bosons loaded in the orbital angular momentum states in a lattice of rings with alternating distances.…
Kaleidoscopes of Hofstadter Butterflies and Aharonov-Bohm caging from -root topology in decorated square lattices
A. M. Marques, J. Mögerle, G. Pelegrí +3
Square-root topology describes models whose topological properties can be revealed upon squaring the Hamiltonian, which produces their respective parent topological insulators. Thi…
Many-body Aharonov-Bohm caging in a lattice of rings
Eloi Nicolau, Anselmo M. Marques, Ricardo G. Dias +2
We study a system of a few ultracold bosons loaded into the states with orbital angular momentum of a one-dimensional staggered lattice of rings. Local eigenstates with windi…
Interaction-induced topological properties of two bosons in flat-band systems
G. Pelegrí, A. M. Marques, V. Ahufinger +2
In flat-band systems, destructive interference leads to the localization of non-interacting particles and forbids their motion through the lattice. However, in the presence of inte…
Second-order topological corner states with ultracold atoms carrying orbital angular momentum in optical lattices
G. Pelegrí, A. M. Marques, V. Ahufinger +2
We propose a realization of a two-dimensional higher-order topological insulator with ultracold atoms loaded into orbital angular momentum (OAM) states of an optical lattice. The s…
