Selective Mottness as a key to iron superconductors
Luca de' Medici, Gianluca Giovannetti, Massimo Capone
The phase diagram of the high-Tc cuprates is dominated by the Mott insulating phase of the parent compounds. As we approach it from large doping, a standard Fermi-liquid gradually…
Measuring Fermi velocities with ARPES in narrow band systems. The case of layered cobaltates
V. Brouet, A. Nicolaou, M. Zacchigna +3
ARPES is a priori a technique of choice to measure the Fermi velocities vF in metals. In correlated systems, it is interesting to compare this experimental value to that obtained i…
Determining the Short-Range Spin Correlations in Cuprate Chain Materials with Resonant Inelastic X-ray Scattering
Claude Monney, Valentina Bisogni, Ke Jin Zhou +13
We report a high-resolution resonant inelastic soft x-ray scattering study of the quantum magnetic spin-chain materials Li2CuO2 and CuGeO3. By tuning the incoming photon energy to…
Momentum-resolved evolution of the Kondo lattice into 'hidden-order' in URu2Si2
F. L. Boariu, C. Bareille, H. Schwab +5
We study, using high-resolution angle-resolved photoemission spectroscopy, the evolution of the electronic structure in URu2Si2 at the Gamma, Z and X high-symmetry points from the…
Spin liquid correlations, anisotropic exchange and symmetry breaking in Tb2Ti2O7
Sylvain Petit, Pierre Bonville, Julien Robert +2
We have studied the low energy spin dynamics between 4.6K and 0.07K in a Tb2Ti2O7 single crystal sample, by means of inelastic neutron scattering experiments. The spectra consist i…
Geometry fluctuations and Casimir effect in a quantum antiferromagnet
Anuradha Jagannathan, Attila Szallas
We show the presence of a Casimir type force between domain walls in a two dimensional Heisenberg antiferromagnet subject to geometrical fluctuations. The type of fluctuations that…
Exchange energies of Kapellasite from high-temperature series analysis of the kagome lattice J1-J2-Jd-Heisenberg model
B. Bernu, C. Lhuillier, E. Kermarrec +4
We present a method to build magnetic models for insulators based on high-temperature expansions by fitting both the magnetic susceptibility and the low temperature specific heat d…
A resistor model for quantum criticality: quasi one-dimensional organic conductors
H. Meier, P. Auban-Senzier, C. Pépin +1
We investigate the metallic transport in the organic superconductor (TMTSF)2PF6 under pressure within the framework of the spin density wave theory in the proximity of a Peierls qu…
Localization of spinons in random Majumdar-Ghosh chains
Arthur Lavarélo, Guillaume Roux
We study the effect of disorder on frustrated dimerized spin-1/2 chains at the Majumdar-Ghosh point. Using variational methods and density-matrix renormalization group approaches,…
Low temperature ballistic spin transport in the S=1/2 antiferromagnetic Heisenberg chain compound SrCuO2
H. Maeter, A. A. Zvyagin, H. Luetkens +7
We report zero and longitudinal magnetic field muon spin relaxation measurements of the spin S=1/2 antiferromagnetic Heisenberg chain material SrCuO2. We find that in a weak applie…
Lightly stuffed pyrochlore structure of single-crystalline Yb2Ti2O7 grown by the optical floating zone technique
K. A. Ross, Th. Proffen, H. A. Dabkowska +4
Recent neutron scattering and specific heat studies on the pyrochlore Yb2Ti2O7 have revealed variations in its magnetic behavior below 265mK. In the best samples, a sharp anomaly i…
Singlet Ground State of the Quantum Antiferromagnet Ba3CuSb2O9
J. A. Quilliam, F. Bert, E. Kermarrec +6
We present local probe results on the honeycomb lattice antiferromagnet Ba3CuSb2O9. Muon spin relaxation measurements in zero field down to 20 mK show unequivocally that there is a…
Magneto-elastic coupling in the spin-Peierls ground state of hydrogenated and deuterated (TMTTF)PF salts
Mario Poirier, Alexandre Langlois, Claude Bourbonnais +3
We report an ultrasonic study of the magneto-elastic coupling of the hydrogenated and deuterated (TMTTF)PF organic salts. For both salts the temperature dependence of the l…
Strong electronic correlations from Hund's coupling
Antoine Georges, Luca de' Medici, Jernej Mravlje
Strong electronic correlations are often associated with the proximity of a Mott insulating state. In recent years however, it has become increasingly clear that the Hund's rule co…
Critical phenomena and phase sequence in classical bilayer Wigner crystal at zero temperature
L. Samaj, E. Trizac
We study the ground-state properties of a system of identical classical Coulombic point particles, evenly distributed between two equivalently charged parallel plates at distance $…
Edge properties of principal fractional quantum Hall states in the cylinder geometry
Paul Soulé, Thierry Jolicoeur
We study fractional quantum Hall states in the cylinder geometry with open boundaries. We focus on principal fermionic 1/3 and bosonic 1/2 fractions in the case of hard-core intera…
Dimensional crossover of spin chains in a transverse staggered field: an NMR study
F. Casola, T. Shiroka, V. Glazkov +6
Heisenberg spin-1/2 chain materials are known to substantially alter their static and dynamic properties when experiencing an effective transverse staggered field originating from…
Exploring the Dark Side of Cuprate Superconductors: s-wave Symmetry of the Pseudogap

We reveal the full energy-momentum structure of the pseudogap of underdoped high-Tc cuprate superconductors. Our combined theoretical and experimental analysis explains the spectra…
Impact of the 2 Fe unit cell on the electronic structure measured by ARPES in iron pnictides
V. Brouet, M. Fuglsang Jensen, Ping-Hui Lin +7
In all iron pnictides, the positions of the ligand alternatively above and below the Fe plane create 2 inequivalent Fe sites. This results in 10 Fe 3d bands in the electronic struc…
Electronic correlations, Jahn-Teller distortions and Mott transition to superconductivity in alkali-C60 compounds
Henri Alloul
The discovery in 1991 of high temperature superconductivity (SC) in A3C60 compounds, where A is an alkali ion, has been rapidly ascribed to a BCS mechanism, in which the pairing is…
Ground state of classical bilayer Wigner crystals
L. Samaj, E. Trizac
We study the ground state structure of electronic-like bilayers, where different phases compete upon changing the inter-layer separation or particle density. New series representat…
