A many-particle system must posses long-range interactions in order to be hyperuniform at thermal equilibrium. Hydrodynamic arguments and numerical simulations show, nevertheless, that a three-dimensional elastic-line array with short-ranged repulsive interactions, such as vortex matter in a type-II superconductor, forms at equilibrium a class-II hyperuniform two-dimensional point pattern for any constant-$z$ cross section. In this case, density fluctuations vanish isotropically as $\sim q…

Disordered hyperuniformity in superconducting vortex lattices

Particles occupying sites of a random lattice present density fluctuations at all length scales. It has been proposed that increasing interparticle interactions reduces long range density

Anisotropic suppression of hyperuniformity of elastic systems in media with planar disorder

Disordered hyperuniform materials with vanishing long-wavelength density fluctuations are attracting attention due to their unique physical properties. In these systems, the large-scale density

Jamming, fragility and pinning phenomena in superconducting vortex systems

The sequential perpendicular driving protocol proposed for distinguishing fragile, jammed, and pinned phases should be general to the broader class of driven interacting particles in the presence of quenched disorder.

Non-Gaussian tail in the force distribution: a hallmark of correlated disorder in the host media of elastic objects

A method to discern whether weak-point or strong-correlated disorder dominates based on characterizing the distribution of the interaction forces between objects mapped in large fields-of-view, and proposes that detecting this deviation from the Gaussian behavior is a fingerprint of strong disorder.



Translational correlations in the vortex array at the surface of a type-II superconductor.

It is found that surface interaction always dominates in determining the decay of translational correlations in the asymptotic long-wavelength limit.

Boson localization and correlated pinning of superconducting vortex arrays.

A theory of vortex pinning in high-temperature superconductors by correlated disorder in the form of twin boundaries, grain boundaries, and columnar defects is described, and a scaling theory for the flux-liquid to Bose-glass transition, at which the linear resistivity vanishes is proposed.

Unveiling the vortex glass phase in the surface and volume of a type-II superconductor

Order-disorder transitions between glassy phases are common in nature and yet a comprehensive survey on the entailed structural changes is challenging since the constituents are in the micro-scale.

A Bragg glass phase in the vortex lattice of a type II superconductor

Although crystals are usually quite stable, they are sensitive to a disordered environment: even an infinitesimal amount of impurities can lead to the destruction of crystalline order. The resulting

Enhanced pinning for vortices in hyperuniform pinning arrays and emergent hyperuniform vortex configurations with quenched disorder

Disordered hyperuniformity is a state of matter which has isotropic liquid like properties while simultaneously having crystalline like properties such as little variation in the density fluctuations

Correlations in flux liquids with weak disorder.

The response of an entangled flux liquid to a quenched random potential is studied and it is shown that disorder does become relevant sufficiently close to {ital H}{sub {ital c}1}, where it is no longer screened out by thermal fluctuations.

Nonequilibrium Steady States of Driven Periodic Media

We study a periodic medium driven over a random or periodic substrate. Our work is based on nonequilibrium continuum hydrodynamic equations of motion, which we derive microscopically. We argue that

Moving glass theory of driven lattices with disorder

We study periodic structures, such as vortex lattices, moving in a random pinning potential under the action of an external driving force. As predicted in T. Giamarchi and P. Le Doussal, Phys. Rev.

Observation of smectic and moving-Bragg-glass phases in flowing vortex lattices

The defining characteristic of the superconducting state is its ability to carry electrical currents without loss. The process by which it does this has been extensively studied for decades but there
