Distinguishing Majorana zero modes from trivial defect states in an iron-based superconductor
Dongfei Wang, Jon Ortuzar, Freek Massee +5
Majorana zero modes, which obey non-Abelian exchange statistics, are promising candidates for topological quantum computation due to their robustness against environmental perturba…
Charge-tunable Cooper-pair diode
Jon Ortuzar, Stefano Trivini, Leonard Edens +2
Superconducting diodes, devices that allow Cooper-pair currents to flow more easily in one direction than the other, are set to become key building blocks for dissipationless elect…
Superconducting Spin-Singlet QuBit in a Triangulene Spin Chain
Chen-How Huang, Jon Ortuzar, M. A. Cazalilla
Chains of triangular nanographene (triangulene), recently identified as realizing the valence-bond solid phase of a spin-1 chain, offer a promising platform for quantum information…
Topological Engineering of a Frustrated Antiferromagnetic Triradical in Aza-Triangulene Architectures
Francisco Romero-Lara, Manuel Vilas-Varela, Ricardo Ortiz +19
Open-shell nanographenes provide a versatile platform to host unconventional magnetic states within their π-conjugated networks. Particularly appealing are graphene architectures t…
Local control of parity and charge in nanoscale superconducting lead islands
Stefano Trivini, Jon Ortuzar, Katerina Vaxevani +3
Small superconducting islands can exhibit charge quantization, where Coulomb interactions compete with Cooper pairing. Using scanning tunneling spectroscopy, we probe this interpla…
Epitaxial growth of gold films on the elemental superconductors V(100), Nb(100) and Nb(110)
Dongfei Wang, Katerina Vaxevani, Danilo Longo +7
Quantum technologies require a new generation of superconducting electronic devices and circuitry. However, the superconducting materials used to construct them are restricted to a…
