Magnetic field enhancement of superconductivity in ultra-narrow wires (2006)
Rogachev, A., Wei, T. -C., Pekker, D., Bollinger, A. T., Goldbart, P. M., Bezryadin, A.
We study the effect of an applied magnetic field on sub-10nm wide MoGe and Nb superconducting wires. We find that magnetic fields can enhance the critical supercurrent at low temperatures, and does...
Density-Correlator Signatures of the Vulcanization Transition (2001)
Societa Italiana Di Fisica, W. Peng, P. M. Goldbart
. Certain density correlators, measurable via various experimental techniques, are studied in the context of the vulcanization transition. It is shown that these correlators contain essential...
Lyanda-Geller, Y., Chun, S. H., Salamon, M. B., Goldbart, P. M., Han, P. D., Tomioka, Y., ...
The low-temperature Hall resistivity \rho_{xy} of La_{2/3}A_{1/3}MnO_3 single crystals (where A stands for Ca, Pb and Ca, or Sr) can be separated into Ordinary and Anomalous contributions, giving...
Magnetotransport in manganites and the role of quantal phases I: Theory (1999)
Lyanda-Geller, Y., Goldbart, P. M., Chun, S. H., Salamon, M. B.
A microscopic picture of charge transport in manganites is developed, with particular attention being paid to the neighborhood of the ferromagnet-to- paramagnet phase transition. The basic transport...
Magnetotransport in manganites and the role of quantal phases II: Experiment (1999)
Chun, S. H., Salamon, M. B., Han, P. D., Lyanda-Geller, Y., Goldbart, P. M.
As in conventional ferromagnets, the Hall resistivity rho_xy of a La_{2/3}(Ca,Pb)_{1/3}MnO_3 single crystal exhibits both ordinary and anomalous contributions at low temperature. However, these...
