Quantized magnetization density in periodically driven systems
Frederik Nathan, Mark S. Rudner, Netanel H. Lindner +2
We study micromotion in two-dimensional periodically driven systems in which all bulk Floquet eigenstates are localized by disorder. We show that this micromotion gives rise to a q…
Topological Superconductivity in a Planar Josephson Junction
Falko Pientka, Anna Keselman, Erez Berg +3
We consider a two-dimensional electron gas with strong spin-orbit coupling contacted by two superconducting leads, forming a Josephson junction. We show that in the presence of an…
Topological transitions and fractional charges induced by strain and magnetic field in carbon nanotubes
Yonathan Efroni, Shahal Ilani, Erez Berg
We show that carbon nanotubes (CNT) can be driven through a topological phase transition using either strain or a magnetic field. This can naturally lead to Jackiw-Rebbi soliton st…
Interaction-driven topological superconductivity in one dimension
Arbel Haim, Konrad Wölms, Erez Berg +2
We study one-dimensional topological superconductivity in the presence of time-reversal symmetry. This phase is characterized by having a bulk gap, while supporting a Kramers' pair…
No-go theorem for a time-reversal invariant topological phase in noninteracting systems coupled to conventional superconductors
Arbel Haim, Erez Berg, Karsten Flensberg +1
We prove that a system of non-interacting electrons proximity coupled to a conventional s-wave superconductor cannot realize a time reversal invariant topological phase. This is do…
Signatures of topological Josephson junctions
Yang Peng, Falko Pientka, Erez Berg +2
Quasiparticle poisoning and diabatic transitions may significantly narrow the window for the experimental observation of the -periodic Josephson effect predicted for topol…
