Magnetic-field enhancement of superconductivity in ultranarrow wires.
We study the effect of an applied magnetic field on sub-10-nm wide MoGe and Nb superconducting wires. We find that magnetic fields can enhance the critical supercurrent at low temperatures, and do so more strongly for narrower wires. We conjecture that magnetic moments are present, but their pair-breaking effect, active at lower magnetic fields, is suppressed by higher fields. The corresponding...
متن کاملOn Color Superconductivity in External Magnetic Field
We study color superconductivity in external magnetic field. We discuss the reason why the mixing angles in color-flavor locked (CFL) and two-flavor superconductivity (2SC) phases are different despite the fact that the CFL gap goes to the 2SC gap for ms → ∞. Although flavor symmetry is explicitly broken in external magnetic field, we show that all values of gaps in their coset spaces of possib...
متن کاملColour superconductivity in a strong magnetic field
We explore the effects of an applied strong external magnetic field in a three flavour massless colour superconductor. The long-range component of the B field that penetrates the superconductor enhances some quark condensates, leading to a different condensation pattern. The external field also reduces the flavour symmetries in the system, and thus it changes drastically the corresponding low e...
متن کاملEnhancement of Bone Healing by Static Magnetic Field in the Dog: Biomechanical Study
Objective- Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF)have been well demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study,effects of SMFs on clinical and biomechanical aspects of bone healing using a canine unstable osteotomygap model were investigated .Design- Prospective descriptive trial.Animals- Fifteen mongre...
