A consistent description of the confining QCD vacuum as a dual superconductor requires a determination of fundamental parameters such as the superconductor correlation length ξ and the field penetration depth λ, which determine whether the superconductor is of type I or type II. We illustrate preliminary results of a lattice determination of ξ for the case of pure Yang-Mills with two colors, ob...

Indium Antimonide (InSb) is a semiconductor material with unique properties, that are suitable for studying new quantum phenomena in hybrid semiconductor-superconductor devices. The realization of such devices defect-free InSb thin films challenging, since has large lattice mismatch most common insulating substrates. Here, the controlled synthesis free-standing 2D nanostructures, termed as “nan...

We address, within the dual superconductivity model for color confinement, the question whether the Yang-Mills vacuum behaves as a superconductor of type I or type II. In order to do that we compare, for the theory with gauge group SU (2), the determination of the field penetration depth λ with that of the superconductor correlation length ξ. The latter is obtained by measuring the temporal cor...

Quantum materials with non-trivial band topology and bulk superconductivity are considered superior to realize topological superconductivity. In this regard, we report detailed density functional theory (DFT) calculations Z2 invariants for the NbC superconductor, exhibiting its structure be topologically non-trivial. Bulk at 8.9 K is confirmed through DC magnetization measurements under field c...

– An extreme type II superconductor with internal insulating regions, namely cavities, is studied here. We find that the cavity-bearing superconductor has lower energy than the defectfree superconductor above a critical magnetic induction B∗ for insulating cavities but not for metallic ones. Using a numerical approach for the Ginzburg-Landau theory we compute and compare free energy densities f...

Lifting capacities greater than 41 N/cm2 (60 psi) at 77 K have been achieved using a combination of permanent magnets and high quality melt-textured YBa,Cu,O,-s (YBCO). The key concept of this hybrid superconducting magnetic bearing (HSMB) is the use of strong magnetic repulsion and attraction from permanent magnets to support high loads in conjunction with flux pinning in a type II superconduc...
