Liquid marbles

P Aussillous, D Quéré - Nature, 2001 - nature.com
The transport of a small amount of liquid on a solid is not a simple process, owing to the
nature of the contact between the two phases. Setting a liquid droplet in motion requires non …

Electronic thermal conductivity and the Wiedemann-Franz law for unconventional superconductors

MJ Graf, SK Yip, JA Sauls, D Rainer - Physical Review B, 1996 - APS
We use the quasiclassical theory of superconductivity to calculate the electronic contribution
to the thermal conductivity. The theory is formulated for low temperatures when heat …

Pairing symmetry in a two-orbital exchange coupling model of oxypnictides

K Seo, BA Bernevig, J Hu - Physical review letters, 2008 - APS
We study the pairing symmetry of a two-orbital J 1-J 2 model for FeAs layers in oxypnictides.
We show that the mixture of an intraorbital unconventional sx 2 y 2∼ cos⁡(kx) cos⁡(ky) …

Quasiparticle scattering interference in high-temperature superconductors

QH Wang, DH Lee - Physical Review B, 2003 - APS
We propose that the energy-dependent spatial modulation of the local density of states seen
by Hoffman et al.[Science 297, 1148 (2002)] is due to the scattering interference of …

Interplay of magnetism and high-Tc superconductivity at individual Ni impurity atoms in Bi2Sr2CaCu2O8+δ
