Ising metamagnets and their ferroelectric analogs are excellent systems in which to study the effects of frustration.

Composite fermion (CF) metal states emerge in quantum Hall bilayers at total Landau level filling factor v(T) = 1 when the tunneling gap collapses by application of in-plane component of the magnet

Considering a noncentrosymmetric pinning texture composed of a square array of triangular holes, the magnetic flux penetration and expulsion are investigated experimentally and theoretically.

We have found in recent studies that a great deal about the dynamics of Charge Density Wave (CDW) behavior for materials in which the CDW can be depinned from the lattice can be learned by investig

Incommensurate charge-density-waves pinned by disorder show an interplay between spatial disorder and non-linear dynamics.

Unusual metastable and polarization behavior has been observed for al(0.48)ln(0.52)As/Ga(0.47)ln(0.53)As avalanche photodiodes by capacitance spectroscopy.

We study the solutions of linear Schrodinger equations in which the potential energy is a periodic function of time and is sufficiently localized in space.

Charge density waves pinned by disorder have many possible metastable configurations.

Metastable defect structures exhibit structural transformations between different atomic configurations under specific conditions of measurement or device operation.

In half-filled high Landau levels, two-dimensional electron systems possess collective phases which exhibit a strongly anisotropic resistivity tensor.
