InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Study of bosons produced in association with charm in the forward region
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994
Events containing a boson and a charm jet are studied for the first time in the forward region of proton-proton collisions. The data sample used corresponds to an integrated lu…
Study of the doubly charmed tetraquark
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994
An exotic narrow state in the mass spectrum just below the mass threshold is studied using a data set corresponding to an integrated luminosity of 9 fb$^{-1…
Measurement circuit effects in three-terminal electrical transport measurements
Esteban A. Martinez, Andreas Pöschl, Esben Bork Hansen +4
In this article we study measurement circuit effects in three-terminal electrical transport measurements arising from finite line impedances. We provide exact expressions relating…
Nonlocal conductance spectroscopy of Andreev bound states: Symmetry relations and BCS charges
Jeroen Danon, Anna Birk Hellenes, Esben Bork Hansen +3
Two-terminal conductance spectroscopy of superconducting devices is a common tool for probing Andreev and Majorana bound states. Here, we study theoretically a three-terminal setup…
Hybridization of sub-gap states in one-dimensional superconductor/semiconductor Coulomb islands
E. C. T. O'Farrell, A. C. C. Drachmann, M. Hell +10
We present measurements of one-dimensional superconductor-semiconductor Coulomb islands, fabricated by gate confinement of a two-dimensional InAs heterostructure with an epitaxial…
Probing electron-hole components of subgap states in Coulomb blockaded Majorana islands
Esben Bork Hansen, Jeroen Danon, Karsten Flensberg
Recent tunneling spectroscopy experiments in semiconducting nanowires with proximity-induced superconductivity have reported robust zero-bias conductance peaks. Such a feature can…
Conductance spectroscopy on Majorana wires and the inverse proximity effect
Jeroen Danon, Esben Bork Hansen, Karsten Flensberg
Recent experimental searches for signatures of Majorana-like excitations in proximitized semiconducting nanowires involve conductance spectroscopy, where the evidence sought after…
Majorana bound states in a coupled quantum-dot hybrid-nanowire system
M. T. Deng, S. Vaitiekenas, E. B. Hansen +6
Hybrid nanowires combining semiconductor and superconductor materials appear well suited for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate th…
Transport signatures of quasiparticle poisoning in a Majorana island
S. M. Albrecht, E. B. Hansen, A. P. Higginbotham +7
We investigate effects of quasiparticle poisoning in a Majorana island with strong tunnel coupling to normal-metal leads. In addition to the main Coulomb blockade diamonds, "shadow…
Phase-tunable Majorana bound states in a topological N-SNS junction
Esben Bork Hansen, Jeroen Danon, Karsten Flensberg
We theoretically study the differential conductance of a one-dimensional normal-superconductor-normal-superconductor (N-SNS) junction with a phase bias applied between the two supe…
