Interacting Arrays of Steps and Lines in Random Media
J. Kierfeld, T. Hwa
The phase diagram of two interacting planar arrays of directed lines in random media is obtained by a renormalization group analysis. The results are discussed in the contexts of t…

Topological Order in the Vortex Glass Phase of High-Temperature Superconductors
J. Kierfeld, T. Nattermann, T. Hwa
The stability of a vortex glass phase with quasi-long-range positional order is examined for a disordered layered superconductor. The role of topological defects is investigated us…

Disorder-Induced Depinning Transition
Terence Hwa, Thomas Nattermann
The competition in the pinning of a directed polymer by a columnar pin and a background of random point impurities is investigated systematically using the renormalization group me…
