Quantum metric of non-Hermitian Su-Schrieffer-Heeger systems
Chao Chen Ye, W. L. Vleeshouwers, S. Heatley +2
Topological insulators have been studied intensively over the last decades. Earlier research focused on Hermitian Hamiltonians, but recently, peculiar and interesting properties we…
Breaking and resurgence of symmetry in the non-Hermitian Su-Schrieffer-Heeger model in photonic waveguides
E. Slootman, W. Cherifi, L. Eek +4
Symmetry is one of the cornerstones of modern physics and has profound implications in different areas. In symmetry-protected topological systems, symmetries are responsible for pr…
Corner modes of the breathing kagome lattice: origin and robustness
M. A. J. Herrera, S. N. Kempkes, M. Blanco de Paz +3
We study the non-trivial phase of the two-dimensional breathing kagome lattice, displaying both edge and corner modes. The corner localized modes of a two-dimensional flake were in…
Spin-orbit gaps in the s and p orbital bands of an artificial honeycomb lattice
J. J. van den Broeke, I. Swart, C. Morais Smith +1
Muffin-tin methods have been instrumental in the design of honeycomb lattices that show, in contrast to graphene, separated s and in-plane p bands, a p orbital Dirac cone, and a p…
Shining Light on Quantum Transport in Fractal Networks
Xiao-Yun Xu, Xiao-Wei Wang, Dan-Yang Chen +2
Fractals are fascinating structures, not only for their aesthetic appeal, but also because they allow for the investigation of physical properties in non-integer dimensions. In the…
Projected Proca Field Theory: a One-Loop Study
R. F. Ozela, Van Sérgio Alves, E. C. Marino +4
The recent discovery of two-dimensional Dirac materials, such as graphene and transition-metaldichalcogenides, has raised questions about the treatment of hybrid systems, in which…
