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…
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…
Flux-mediated effective Su-Schrieffer-Heeger model in an impurity decorated diamond chain
David Viedma, Anselmo M. Marques, Ricardo G. Dias +1
In flat-band systems with non-orthogonal compact localized states (CLSs), onsite perturbations couple neighboring CLSs and generate exponentially-decaying impurity states, whose de…
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…
Topological -root Su-Schrieffer-Heeger model in a non-Hermitian photonic ring system
David Viedma, Anselmo M. Marques, Ricardo G. Dias +1
Square-root topology is one of the newest additions to the ever expanding field of topological insulators (TIs). It characterizes systems that relate to their parent TI through the…
Multihole edge states in Su-Schrieffer-Heeger chains with interactions
A. M. Marques, R. G. Dias
We address the effect of nearest-neighbor (NN) interactions on the topological properties of the Su-Schrieffer-Heeger (SSH) chain, with alternating hopping amplitudes t1 and t2. Bo…
