Autor: Freeney, S. E., Broeke, J. J. van den, van der Veen, A. J. J. Harsveld, Swart, I., Smith, C. Morais

Publikováno v: Phys. Rev. Lett. 124, 236404 (2020)

Topological states of matter are robust quantum phases, characterised by propagating or localised edge states in an insulating bulk. Topological boundary states can be triggered by various mechanisms, for example by strong spin-orbit coupling. In thi

Scanning Probe State Recognition With Multi-Class Neural Network Ensembles

Autor: Gordon, O., D'Hondt, P., Knijff, L., Freeney, S., Junqueira, F., Moriarty, P., Swart, I.

One of the largest obstacles facing scanning probe microscopy is the constant need to correct flaws in the scanning probe in situ. This is currently a manual, time-consuming process that would benefit greatly from automation. Here we introduce a conv

Design and characterization of electronic fractals

Autor: Kempkes, S. N., Slot, M. R., Freeney, S. E., Zevenhuizen, S. J. M., Vanmaekelbergh, D., Swart, I., Smith, C. Morais

Publikováno v: Nature Physics 15, 127-131 (2019)

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, very little is known about the behavior of electrons in non-integer, i
