Hysteresis and hierarchies: dynamics of disorder-driven first-order phase transformations
James P. Sethna, Karin Dahmen, Sivan Kartha +3
We use the zero-temperature random-field Ising model to study hysteretic behavior at first-order phase transitions. Sweeping the external field through zero, the model exhibits hys…
Electromagnetic response of a static vortex line in a type-II superconductor : a microscopic study
Boldizsar Janko, Joel D. Shore
The electromagnetic response of a pinned Abrikosov fluxoid is examined in the framework of the Bogoliubov-de Gennes formalism. The matrix elements and the selection rules for both…
Logarithmically slow domain growth in nonrandomly frustrated systems--- A summary of the major results
Joel D. Shore, James P. Sethna, Mark Holzer +1
Here, we summarize the most important results of our study of logarithmically slow growth of domains following a quench in two models without randomness in their Hamiltonians. This…
Logarithmically slow domain growth in nonrandomly frustrated systems: Ising models with competing interactions
Joel D. Shore, Mark Holzer, James P. Sethna
It is known that in systems which contain randomness explicitly in their Hamiltonians (e.g., due to impurities), the characteristic size L of the ordered domains can grow only loga…
