A topological field-effect memristor
Manuel Meyer, Selena Barragan, Sergey Krishtopenko +13
Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing…
Quantum spin Hall effect in III-V semiconductors at elevated temperatures: advancing topological electronics
Manuel Meyer, Jonas Baumbach, Sergey Krishtopenko +13
The quantum spin Hall effect (QSHE), a hallmark of topological insulators, enables dissipationless, spin-polarized edge transport and has been predicted in various two-dimensional…
Quasiparticle picture of topological phase transitions induced by interactions
S. S. Krishtopenko, A. V. Ikonnikov, F. Hartmann +3
We present a general recipe to describe topological phase transitions in condensed matter systems with interactions. We show that topological invariants in the presence of interact…
Spin-dependent photovoltage in graphene/MoS2-based field-effect transistors
K. Dinar, J. Delgado-Notario, C. Bray +14
It has recently been shown that Terahertz sensors can effectively detect the spin resonances of Dirac fermions in graphene. The associated photovoltaic measurement technique allows…
