Effects of Disorder in the Fibonacci Quasicrystal
Anouar Moustaj, Sander Kempkes, Cristiane Morais Smith
We study the properties of the one-dimensional Fibonacci chain, subjected to the placement of on-site impurities. The resulting disruption of quasiperiodicity can be classified in…
Thermodynamics of a Higher-Order Topological Insulator
R. Arouca, S. N. Kempkes, C. Morais Smith
We investigate the order of the topological quantum phase transition in a two dimensional quadrupolar topological insulator within a thermodynamic approach. Using numerical methods…
p-band engineering in artificial electronic lattices
M. R. Slot, S. N. Kempkes, E. J. Knol +7
Artificial electronic lattices, created atom by atom in a scanning tunneling microscope, have emerged as a highly tunable platform to realize and characterize the lowest-energy ban…
Robust zero-energy modes in an electronic higher-order topological insulator: the dimerized Kagome lattice
S. N. Kempkes, M. R. Slot, J. J. van den Broeke +6
Quantum simulators are an essential tool for understanding complex quantum materials. Platforms based on ultracold atoms in optical lattices and photonic devices led the field so f…
Design and characterization of electronic fractals
S. N. Kempkes, M. R. Slot, S. E. Freeney +4
The dimensionality of an electronic quantum system is decisive for its properties. In 1D electrons form a Luttinger liquid and in 2D they exhibit the quantum Hall effect. However,…
Critical Behavior of Topological Kondo Insulators
J. J. van den Broeke, S. N. Kempkes, A. Quelle +1
A thermodynamic study of the Kondo insulator SmB is pursued to elucidate the well-known anomalous low-temperature electronic-like specific heat contribution conjectured to aris…
