The 1937 theoretical discovery of Majorana fermions—whose defining property is that they
are their own anti-particles—has since impacted diverse problems ranging from neutrino …

Experimental and theoretical progress toward quantum computation with spins in quantum
dots (QDs) is reviewed, with particular focus on QDs formed in GaAs heterostructures, on …

We consider quasi-one-dimensional Ruderman-Kittel-Kasuya-Yosida (RKKY) systems in
proximity to an s-wave superconductor. We show that a 2 k F peak in the spin susceptibility …

We study a one-dimensional interacting electronic liquid coupled to a 1D array of classical
magnetic moments and to a superconductor. We show that at low energy and temperature …

Most physical systems known to date tend to resist entering the topological phase and must
be<? format?> fine-tuned to reach that phase. Here, we introduce a system in which a key …

Among the broad spectrum of systems predicted to exhibit topological superconductivity and
Majorana fermions, one-dimensional wires with strong spin-orbit coupling provide one of the …

We show that one-dimensional electron systems in the proximity of a superconductor that
support Majorana edge states are extremely susceptible to electron-electron interactions …

Interacting one-dimensional conductors with Rashba spin-orbit coupling are shown to
exhibit a spin-selective Peierls-type transition into a mixed spin-charge-density-wave state …

We study hybrid superconducting-semiconducting nanowires in the presence of Rashba
spin-orbit interaction as well as helical magnetic fields. We show that the interplay between …

Chains of magnetic impurities placed on a superconducting substrate and forming helical
spin order provide a promising venue for realizing a topological superconducting phase. An …
