Breakdown of Fermi-liquid theory in a cuprate superconductor

R. W. Hill, Cyril Proust, Louis Taillefer +2

The behaviour of electrons in solids is remarkably well described by Landau's Fermi-liquid theory, which says that even though electrons in a metal interact they can still be treat…

Evolution of spin excitations in a gapped antiferromagnet from the quantum to the high-temperature limit

M. Kenzelmann, R. A. Cowley, W. J. L. Buyers +3

We have mapped from the quantum to the classical limit the spin excitation spectrum of the antiferromagnetic spin-1 Heisenberg chain system CsNiCl3 in its paramagnetic phase from T…

The properties of Haldane excitations and multi-particle states in the antiferromagnetic spin-1 chain compound CsNiCl

M. Kenzelmann, R. A. Cowley, W. J. L. Buyers +3

We report inelastic time-of-flight and triple-axis neutron scattering measurements of the excitation spectrum of the coupled antiferromagnetic spin-1 Heisenberg chain system CsNiCl…

Evidence for Static Magnetism in the Vortex Cores of Ortho-II YBa $_{2}$ Cu $_{3}$ O $_{6.50}$

R. I. Miller, R. F. Kiefl, J. H. Brewer +8

Evidence for static alternating magnetic fields in the vortex cores of underdoped YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ is reported. Muon spin rotation measurements of the internal magnetic field…

The Kondo Screening Cloud

Ian Affleck

Renormalization group theory of the Kondo effect predicts that an impurity spin is screened by a conduction electron spread over a large distance of order >.1 to 1 micron. This rev…

Temperature Dependence of the Magnetic Penetration Depth in the Vortex State of the Pyrochlore Superconductor, Cd2Re2O7

M. D. Lumsden, S. R. Dunsiger, J. E. Sonier +7

We report transverse field and zero field muon spin rotation studies of the superconducting rhenium oxide pyrochlore, Cd2Re2O7. Transverse field measurements (H=0.007 T) show line…

Magnetic anisotropy of the spin ice compound Dy2Ti2O7

H. Fukazawa, R. G. Melko, R. Higashinaka +2

We report magnetization and ac susceptibility of single crystals of the spin ice compound Dy2Ti2O7. Saturated moments at 1.8 K along the charasteristic axes [100] and [110] agree w…

Highly Anisotropic Gap Function in Borocarbide Superconductor LuNi_2B_2C

Etienne Boaknin, R. W. Hill, Cyril Proust +3

The thermal conductivity of borocarbide superconductor LuNi_2B_2C was measured down to 70 mK (T_c/200) in a magnetic field perpendicular to the heat current from H = 0 to above H_c…

Halo Substructure and Disk Heating in a Lambda CDM Universe

Andreea S. Font, Julio F. Navarro, Joachim Stadel +1

We examine recent suggestions that substructure in cold dark matter (CDM) halos may be in conflict with the presence of thin, dynamically fragile stellar disks. N-body simulations…

Persistent currents through a quantum dot

P. Simon, I. Affleck

We study the persistent currents induced by the Aharonov-Bohm effect in a closed ring which either embeds or is directly side coupled to a quantum dot at Kondo resonance. We predic…

Rung-Rung Current Correlations on a 2-Leg t-J Ladder

D. J. Scalapino, S. R. White, I. Affleck

We report the results of numerical calculations of rung-rung current correlations on a 2-leg t-J ladder with J/t=0.35 for dopings x=0.125 and x=0.19. We find that the amplitude of…

Ultrasound Attenuation in Sr $_{2}$ RuO $_{4}$ : an Angle-Resolved Study of the Superconducting Gap Function

C. Lupien, W. A. MacFarlane, Cyril Proust +3

We present a study of the electronic ultrasound attenuation $α$ in the unconventional superconductor Sr $_{2}$ RuO $_{4}$ . The power law behavior of $α$ at temperatures down to $T_{c} /30$ …

Spin Correlations in Ho $_{2}$ Ti $_{2}$ O $_{7}$ : a Dipolar Spin Ice System

S. T. Bramwell, M. J. Harris, B. C. den Hertog +8

The pyrochlore material $H o_{2} T i_{2} O_{7}$ has been suggested to show ``spin ice'' behaviour. We present neutron scattering and specific heat results that establish unambiguou…
