The peak effect (PE) in the critical current density of type II superconductors has been related to an order-disorder transition in the vortex lattice (VL), but its underlying physics remains a controversial issue. Intrinsic to the PE are strong metastabilities that frequently mask the stationary VL configurations. We follow shaking and thermal protocols in NbSe2 single crystals to access these configurations and examine them by linear ac susceptibility measurements that avoid VL reorganization…

Two step disordering of the vortex lattice across the peak effect in a weakly pinned Type II superconductor, Co0.0075NbSe2
The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning. Here, using
Disordering of the vortex lattice through successive destruction of positional and orientational order in a weakly pinned Co0.0075NbSe2 single crystal
TLDR
Scanning tunnelling spectroscopy in a weakly pinned Co0.0075NbSe2 single crystal shows that the vortex lattice in a 3-dimensional superconductor disorders through successive destruction of positional and orientational order, as the magnetic field is increased across the peak effect.
Erratum: Disordering of the vortex lattice through successive destruction of positional and orientational order in a weakly pinned Co0.0075NbSe2 single crystal
TLDR
The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning, and the existence of a variety of additional non-equilibrium metastable states can be accessed through different thermomagnetic cycling.
AC dynamic reorganization and critical phase transitions in superconducting vortex matter
Vortex matter in type-II superconductors is a model complex system belonging to the vast ensemble of disordered elastic media. In all these systems, depinning occurs when an external drive is
Vortex lattice dynamics in Nb films with competing intrinsic random and artificial periodic pinning
We study vortex lattice (VL) dynamics in patterned Nb films containing dense periodic arrays of sub 50 nm magnetic nanodots or holes, by means of ac susceptibility measurements. For both types of
Order–Disorder Transitions in a Polar Vortex Lattice
Order–disorder transitions are widely explored in various vortex structures in condensed matter physics, that is, in the type‐II superconductors and Bose–Einstein condensates. In this study, the
Force-free state in superconducting single crystal and angular-dependent vortex helical instability
2H-NbSe2 single crystals present intrinsic low pinning values. Therefore, they are ideal materials to explore fundamental properties of vortex lattice behavior. (V, I) characteristics are the
Alternate-current dynamic reorganization and nonequilibrium phase transition in driven vortex matter
Externally driven glassy systems may undergo non-equilibrium phase transitions (NEPTs). In particular, ac-driven systems display special features, like those observed in the vortex matter of

TLDR
The theoretical background in terms of the original (1989) model of dopant-assisted quantum percolation (DAQP), as developed further in some two dozen articles, are analyzed and it is concluded that despite all of the many difficulties, with improved data analysis it may yet be possible to identify quantumPercolative paths.
