Designing Majorana Quasiparticles in InAsP Quantum Dots in InP Nanowires with Variational Quantum Eigenvalue Solver

open access: yesphysica status solidi (b), EarlyView.
This work explores the design of Majorana zero modes in InAsP quatum dots within InP nanowires coupled to a p‐type superconductor. Using atomistic calculations, exact diagonalization, and the variational quantum eigensolver (VQE) method, a variational ansatz for capturing ground state in the topological phase is introduced.

Anomalous Magnetic Response of Annealed V0.60−xSixTi0.40 Alloys within the Superconducting Phase

open access: yesphysica status solidi (b), EarlyView.
Annealed V0.60−xSixTi0.40 alloys exhibit an anomalous magnetic response in their mixed state, where magnetization measured during cooling in the presence of a magnetic field is lower than during warming in the same field. This unusual thermomagnetic response, distinct from conventional type‐II superconductors, is attributed to the high‐field ...

DC‐Driven Fractional Flux Quanta in Two‐Band Superconductors

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The dc‐driven distancing of fractional flux quanta is theoretically analyzed for a dual‐band superconductor with a periodic pinning potential. The analysis is based on the dynamical equation of motion for a single composite vortex. The model neglects the phase difference between the condensates and may be applicable to two‐band superconductors with ...

Vortex Ratchet Effect in Superconductor Open Nanotubes and 3D Nanoflakes

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
Magnetic flux quanta in 3D superconductor nanotubes move in the regions where the normal component of the applied magnetic field is close to maximum. Asymmetric pinning sites placed in these areas result in an enhanced vortex ratchet effect compared to planar systems.

Quantum Depletion of Superconductivity in 3D Diamond Nanowires

open access: yesAdvanced Quantum Technologies, EarlyView.
Heavily boron‐doped polycrystalline diamond nanowires demonstrate an exotic resistive state that alters the trend of the superconducting transition. This reentrant resistive state manifests itself as a peak in the current dependence of voltage and a negative magnetoresistance peak. This suggests that cross‐sectional grain boundaries can promote quantum‐
