Single Abrikosov vortices as quantized information bits
Superconducting digital devices can be advantageously used in future supercomputers because they can greatly reduce the dissipation power and increase the speed of operation. Non-volatile quantized states are ideal for the realization of classical Boolean logics. A quantized Abrikosov vortex represents the most compact magnetic object in superconductors, which can be utilized for creation of hi...
متن کاملQuantum oscillations of self-dual Abrikosov-Nielsen-Olesen vortices
In this paper we present some new results on the quantization of the self dual multi-vortex solutions of the Abelian Higgs model. We also take the opportunity to offer a detailed description of the concepts and techniques that allowed us to compute the one-loop quantum correction to the mass of self-dual Abrikosov-Nielsen-Olesen vortices with one quantum of magnetic flux in the Rapid Communicat...
متن کاملAn Effective String Theory of Abrikosov–Nielsen–Olesen Vortices
We obtain an effective string theory of the Abrikosov–Nielsen–Olesen vortices of the Abelian Higgs model. The theory has an anomaly free effective string action which, when the extrinsic curvature is set equal to zero, yields the Nambu–Goto action. This generalizes previous work in which a string representation was obtained in the London limit, where the magnitude of the Higgs field is fixed. V...
متن کاملTopological defects in the Abrikosov lattice of vortices in type-II superconductors.
The free energy costs for various defects within an Abrikosov lattice of vortices are calculated using the lowest Landau level approximation (LLL). Defect solutions with boundary conditions for lines to meet at a point (crossing defect) and for lines to twist around each other (braid defect) are sought for 2, 3, 6, and 12 lines. Many results have been unexpected, including the nonexistence of a...
متن کاملTransition from slow Abrikosov to fast moving Josephson vortices in iron pnictide superconductors.
Iron pnictides are layered high T(c) superconductors with moderate material anisotropy and thus Abrikosov vortices are expected in the mixed state. Yet, we have discovered a distinct change in the nature of the vortices from Abrikosov-like to Josephson-like in the pnictide superconductor SmFeAs(O,F) with T(c)~48-50 K on cooling below a temperature T*~41-42 K, despite its moderate electronic ani...
