Superconductivity and Antiferromagnetism in Quasi-one-dimensional Organic Conductors
N. Dupuis, C. Bourbonnais, J. C. Nickel
We review the current understanding of superconductivity in the quasi-one-dimensional organic conductors of the Bechgaard and Fabre salt families. We discuss the interplay between…
Superconducting pairing and density-wave instabilities in quasi-one-dimensional conductors
J. C. Nickel, R. Duprat, C. Bourbonnais +1
Using a renormalization group approach, we determine the phase diagram of an extended quasi-one-dimensional electron gas model that includes interchain hopping, nesting deviations…
Effect of Inter-Site Repulsions on Magnetic Susceptibility of One-Dimensional Electron Systems at Quarter-Filling
Yuki Fuseya, Masahisa Tsuchiizu, Yoshikazu Suzumura +1
The temperature dependence of the magnetic susceptibility, χ(T), is investigated for one-dimensional interacting electron systems at quarter-filling within the Kadanoff-Wilson reno…
Potential-energy (BCS) to kinetic-energy (BEC)-driven pairing in the attractive Hubbard model
B. Kyung, A. Georges, A. -M. S. Tremblay
The BCS-BEC crossover within the two-dimensional attractive Hubbard model is studied by using the Cellular Dynamical Mean-Field Theory both in the normal and superconducting ground…
Anomalous superconductivity and its competition with antiferromagnetism in doped Mott insulators
S. S. Kancharla, B. Kyung, D. Senechal +4
Proximity to a Mott insulating phase is likely to be an important physical ingredient of a theory that aims to describe high-temperature superconductivity in the cuprates. Quantum…
Charge Sensing of an Artificial H2+ Molecule
M. Pioro-Ladriere, M. R. Abolfath, P. Zawadzki +4
We report charge detection studies of a lateral double quantum dot with controllable charge states and tunable tunnel coupling. Using an integrated electrometer, we characterize th…
The influence of the long-lived quantum Hall potential on the characteristics of quantum devices
M. Pioro-Ladriere, A. Usher, A. S. Sachrajda +5
Novel hysteretic effects are reported in magneto-transport experiments on lateral quantum devices. The effects are characterized by two vastly different relaxation times (minutes a…
The origin of switching noise in GaAs/AlGaAs lateral gated devices
M. Pioro-Ladrière, J. H. Davies, A. R. Long +7
We have studied the origin of switching (telegraph) noise at low temperature in lateral quantum structures defined electrostatically in GaAs/AlGaAs heterostructures by surface gate…
Unpaired Electrons in the Heavy-Fermion Superconductor CeCoIn_{5}
M. A. Tanatar, Johnpierre Paglione, S. Nakatsuji +9
Thermal conductivity and specific heat were measured in the superconducting state of the heavy fermion material Ce_{1-x}La_{x}CoIn_{5}. With increasing impurity concentration x, th…
Replica study of pinned bubble crystals
R. Côté, Mei-Rong Li, A. Faribault +1
In higher Landau levels (), the ground state of the two-dimensional electron gas in a strong perpendicular magnetic field evolves from a Wigner crystal for small filling o…
Triplet superconducting pairing and density-wave instabilities in organic conductors
J. C. Nickel, R. Duprat, C. Bourbonnais +1
Using a renormalization group approach, we determine the phase diagram of an extended quasi-one-dimensional electron gas model that includes interchain hopping, nesting deviations…
Pseudogap induced by short-range spin correlations in a doped Mott insulator
B. Kyung, S. S. Kancharla, D. Sénéchal +3
We study the evolution of a Mott-Hubbard insulator into a correlated metal upon doping in the two-dimensional Hubbard model using the Cellular Dynamical Mean Field Theory. Short-ra…
Delocalized fermions in underdoped cuprates
Mike Sutherland, S. Y. Li, D. G. Hawthorn +10
Low temperature heat transport was used to investigate the ground state of high-purity single crystals of the lightly-doped cuprate YBaCuO. Samples were measur…
Ballistic magnon transport and phonon scattering in the antiferromagnet NdCuO
S. Y. Li, Louis Taillefer, C. H. Wang +1
The thermal conductivity of the antiferromagnet NdCuO was measured down to 50 mK. Using the spin-flop transition to switch on and off the acoustic Nd magnons, we can reliab…
