Vortex configurations of bosons in an optical lattice
Congjun Wu, Han-dong Chen, Jiang-ping Hu +1
The single vortex problem in a strongly correlated bosonic system is investigated self-consistently within the mean-field theory of the Bose-Hubbard model. Near the superfluid-Mott…
Neutron Scattering, Magnetometry, and Quantum Monte Carlo Study of the Randomly-Diluted Spin-1/2 Square-Lattice Heisenberg Antiferromagnet
O. P. Vajk, M. Greven, P. K. Mang +1
We have successfully grown sizable single crystals of La_2Cu_{1-z}(Zn,Mg)_zO_4 with up to nearly half of the magnetic Cu sites replaced by non-magnetic Zn and Mg. Neutron scatterin…
Electron-phonon interaction in n-doped cuprates: an Inelastic X-ray Scattering study
M. d'Astuto, P. K. Mang, P. Giura +7
Inelastic x-ray scattering (IXS) with very high (meV) energy resolution has become a valuable spectroscopic tool, complementing the well established coherent inelastic neutron scat…
How to detect fluctuating order in the high-temperature superconductors
S. A. Kivelson, E. Fradkin, V. Oganesyan +4
We discuss fluctuating order in a quantum disordered phase proximate to a quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies for extra…
Universality of the Electronic Structure from a Half Filled CuO_2 Plane
F. Ronning, C. Kim, K. M. Shen +9
We present angle resolved photoemission (ARPES) data from insulating A_2CuO_2X_2 (A=Sr, Ca; X=Cl, Br), Sr_2Cu_3O_4Cl_2, and Bi_2Sr_2MCu_2O_8 (M=Er, Dy) single crystals which illust…
Transport spin polarisation in SrRuO3 measured through Point Contact Andreev reflection
P. Raychaudhuri, A. P. Mackenzie, J. W. Reiner +1
We report a study in which Andreev reflection using a Nb point contact is used to measure the transport spin polarisation of the 4d itinerant ferromagnet SrRuO3. By performing the…
Magnetic Properties and Phase Diagram of Li-doped La(2)CuO(4): Common Magnetic Response of Hole-doped CuO2 Planes
T. Sasagawa, P. K. Mang, O. P. Vajk +2
Although La(2)Cu(1-x)Li(x)O(4) [Li-LCO] differs from La(2-x)Sr(x)CuO(4) [Sr-LCO] in many ways (e.g., the absence of metallic transport, high-Tc superconductivity, and incommensurat…
Sliding Density-Wave in Sr_{14}Cu_{24}O_{41} Ladder Compounds
G. Blumberg, P. Littlewood, A. Gozar +4
We used transport and Raman scattering measurements to identify the insulating state of self-doped spin 1/2 two-leg ladders of Sr_{14}Cu_{24}O_{41} as a weakly pinned, sliding dens…
Collective density wave excitations in two-leg Sr_{14-x}Ca_xCu_{24}O_{41} ladders
A. Gozar, G. Blumberg, P. B. Littlewood +4
Raman measurements in the 1.5 - 20 cm-1 energy range were performed on single crystals of Sr_{14-x}Ca_xCu_{24}O_{41}. A quasielastic scattering peak (QEP) which softens with coolin…
Scaling properties of the projected SO(5) model in three dimensions
M. Jöstingmeier, A. Dorneich, E. Arrigoni +2
We study the scaling properties of the quantum ``projected'' SO(5) model in three dimensions by means of a highly accurate Quantum-Monte-Carlo analysis. Within the parameter regime…
Nodal metallic behavior of lightly-doped LaSrCuO
T. Yoshida, X. J. Zhou, T. Sasagawa +10
Lightly-doped LaSrCuO in the so-called "insulating" spin-glass/diagonal-stripe phase has been studied by angle-resolved photoemission spectroscopy. A quasi-particle…
Competing Orders in Coupled Luttinger Liquids
Congjun Wu, W. Vincent Liu, Eduardo Fradkin
We consider the problem of two coupled Luttinger liquids both at half filling and at low doping levels, to investigate the problem of competing orders in quasi-one-dimensional stro…
Quantum Impurities in the Two-Dimensional Spin One-Half Heisenberg Antiferromagnet
O. P. Vajk, P. K. Mang, M. Greven +2
The study of randomness in low-dimensional quantum antiferromagnets is at the forefront of research in the field of strongly correlated electron systems, yet there have been relati…
Three-dimensional flux states as a model for the pseudogap phase of transition metal oxides
D. F. Schroeter, S. Doniach
We propose that the pseudogap state observed in the transition metal oxides can be explained by a three-dimensional flux state, which exhibits spontaneously generated currents in i…
Thermodynamic properties of the d-density wave order in cuprates
Congjun Wu, W. Vincent Liu
We solve a popular effective Hamiltonian of competing -density wave and d-wave superconductivity orders self-consistently at the mean-field level for a wide range of doping and…
Doping dependence of an n-type cuprate superconductor investigated by ARPES
N. P. Armitage, F. Ronning, D. H. Lu +12
We present an angle resolved photoemission (ARPES) doping dependence study of the n-type cuprate superconductor Nd_2-xCe_xCuO_4, from the half-filled Mott-insulator to the T_c=24K…
