Correlation lengths, disorder, and dynamics of vortex matter as heard through the noise
… the dynamics and possible phase transitions of vortex matter associated with the peak-effect. I emphasize five conclusions: (1) Traditional models of vortex dynamics relying on purely dynamical correlations, rigid bundles, or simple two-state channel flow are invalid in the peak regime …

New features in the phase diagrams of the cuprate high-Tc superconductors mapped using strong magnetic fields
… we reveal an unconventional quantum vortex matter ground state hosting quantum oscillations. This vortex matter ground state is highly resilient to applied magnetic field, but fragile to applied temperature and current. It is characterised by vanishing electrical resistivity, finite …

Computational modelling of the vortex state in high-temperature superconductors
The vortex state in high temperature superconductors is investigated using computer simulations. Vortices are represented as particles and we employ Langevin dynamics to study the statics and dynamics of the system.<br/><br/>We show that the long-range nature of the vortex-vortex interaction can …

Determination of local crystal symmetry in complex, multielement, ferroelectric perovskites and alloys
… polarization nanodomains in ferroelectrics, and vortex matter. A common scheme to these systems is that there exists a distinction between local crystal symmetry and the average, macroscopic symmetry imposed by fluctuations in the crystal lattice. Before we can control and exploit these …

Imaging vortex dynamics in Josephson arrays using magnetic force microscopy
Vortices and vortex lattices play a major role in determining the transport properties of type-II superconductors[1–3], and enable a platform to investigate exotic superconducting physics[4,5]. The study of vortex matter has generally focused on novel states in 2D films and structures, and has …

Fermi Surfaces and Where to Find Them: Quantum Oscillations in Kondo Insulators and High-Temperature Superconductors
… non-ohmic signatures associated with a quantum vortex matter state. In contrast to previous proposals, the quantum oscillations are found to occur well within this gapped vortex phase, as established by their co-existence with zero resistivity and hysteretic torque magnetisation, that are found …
