Topological bound states in a lattice of rings with nearest-neighbour interactions
Yunjia Zhai, Ayaka Usui, Anselmo M. Marques +2
We study interaction-induced bound states in a system of ultracold bosons loaded into the states with orbital angular momentum in a one-dimensional staggered lattice of rings. We c…
Geometrical control of topology with orbital angular momentum modes
Yunjia Zhai, Anselmo M. Marques, Ricardo G. Dias +2
We study how the topological properties of a one-dimensional staggered lattice, loaded into states with orbital angular momentum , can be controlled simply by tuning the relat…
Scalable topological quantum computing based on Sine-Cosine chain models
A. Lykholat, G. F. Moreira, I. R. Martins +3
This work proposes a scalable framework for topological quantum computing using Matryoshka-type Sine-Cosine chains. These chains support high-dimensional qudit encoding within sing…
Quantum transfer in high-root topological insulators
G. F. Moreira, A. Lykholat, R. G. Dias +1
This paper focuses on the quantum state transfer in a one-dimensional (1D) high-root topological insulator (HRTI) with an arbitrary number of domains. We present the possibility of…
Impurity flat band states in the diamond chain
Anselmo M. Marques, David Viedma, Verònica Ahufinger +1
Flat band (FB) systems, featuring dispersionless energy bands, have garnered significant interest due to their compact localized states (CLSs). However, a detailed account on how l…
