Manipulating the topological spin of Majoranas
Stijn R. de Wit, Emre Duman, A. Mert Bozkurt +2
The non-Abelian exchange statistics of Majorana zero modes make them interesting for both technological applications and fundamental research. Unlike their non-Abelian counterpart,…
Visualising Quantum Entanglement Using Interactive Electronic Quantum Dice
B. Folkers, A. van Rossum, A. Brinkman +1
Quantum entanglement remains a challenging concept to teach and visualise due to its microscopic and non-classical nature. We present innovative educational demonstration material…
Observation of the surface hybridization gap in the electrical transport properties of the ultrathin topological insulator (BiSb)Te
Feike van Veen, Sofie Kölling, Stijn R. de Wit +4
We study the three-dimensional topological insulator (BiSb)Te in its ultrathin limit i.e. when the thickness is of the same order as the surface state pen…
Signature of current-induced nuclear spin polarization in (BiSb)Te
Sofie Kölling, İnanç Adagideli, Alexander Brinkman
In systems with spin-momentum locking, such as the surface states of three-dimensional topological insulators, a charge current is spin-polarized and spin-flip interactions between…
Non-Ohmic behavior in (BiSb)Te by Joule heating
Sofie Kölling, Daan H. Wielens, İnanç Adagideli +1
A prerequisite to using the net spin polarization generated by a source-drain bias in three-dimensional topological insulators for spintronic applications, is understanding how suc…
Gate electrode-induced nonreciprocal resistance in topological insulators
Sofie Kölling, Florian R. Westerhof, Alexander Brinkman
A common method of controlling the chemical potential in topological insulators is applying a gate electrode. Simultaneously applying high source-drain bias currents can lead to pa…
