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…
Compact localized boundary states in a quasi-1D electronic diamond-necklace chain
S. N. Kempkes, P. Capiod, S. Ismaili +4
Zero-energy modes localized at the ends of one-dimensional (1D) wires hold great potential as qubits for fault-tolerant quantum computing. However, all the candidates known to date…
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,…
Experimental realization and characterization of an electronic Lieb lattice
Marlou R. Slot, Thomas S. Gardenier, Peter H. Jacobse +6
Geometry, whether on the atomic or nanoscale, is a key factor for the electronic band structure of materials. Some specific geometries give rise to novel and potentially useful ele…
