Evidence of topological superconductivity in planar Josephson junctions
Antonio Fornieri,Alexander M. Whiticar,F. Setiawan,Elías Portolés,Asbjorn Drachmann,Anna Keselman,Sergei Gronin,Candice Thomas,Tian Wang,Ray Kallaher,Geoffrey C. Gardner,Erez Berg,Erez Berg,Michael J. Manfra,Ady Stern,Charles Marcus,Fabrizio Nichele,Fabrizio Nichele +17 more
TL;DR: In this paper, phase-dependent zero-bias peak measured by tunnelling spectroscopy at the end of Josephson junctions realized on a heterostructure consisting of aluminium on indium arsenide was found.
Journal ArticleDOI
Single-ion quantum lock-in amplifier
TL;DR: In this article, a quantum analogue to the classical lock-in amplifier was proposed to increase the sensitivity of a single-spin probe to external magnetic fields. But the quantum lock-ins were not applied to the measurement of parity nonconservation.
Journal ArticleDOI
Topological Superconductivity in a Planar Josephson Junction
TL;DR: In this paper, the phase difference between two superconductors is used to create a topological phase, where the bulk accommodates only electron pairs while the surface also allows for motion of single electrons.
Journal ArticleDOI
Matrix product operators, matrix product states, and ab initio density matrix renormalization group algorithms
TL;DR: In this paper, a matrix product operator/matrix product state algebra within a pure renormalized operator-based matrix renormalization group (DMRG) code is described.

TL;DR: The observation of phase-dependent zero-bias conductance peaks measured by tunnelling spectroscopy at the end of Josephson junctions realized on a heterostructure consisting of aluminium on indium arsenide is reported.
