Flat-band induced local Hilbert space fragmentation
Eloi Nicolau, Anselmo M. Marques, Ricardo G. Dias +1
We demonstrate that a complete class of flat-band lattices with underlying commutative local symmetries exhibit a locally fragmented Hilbert space. The equitable partition theorem…
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.…
Local Hilbert space fragmentation and weak thermalization in Bose-Hubbard diamond necklaces
Eloi Nicolau, Anselmo M. Marques, Jordi Mompart +2
We study Bose-Hubbard models in a family of diamond necklace lattices with central sites. The single-particle spectrum of these models presents compact localized states (CLSs)…
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…
Orbital angular momentum dynamics of Bose-Einstein condensates trapped in two stacked rings
Eloi Nicolau, Jordi Mompart, Bruno Juliá-Díaz +1
We investigate the stability and dynamics of the orbital angular momentum modes of a repulsive Bose-Einstein condensate trapped in two tunnel-coupled rings in a stack configuration…
