Density-functional theory and the v-representability problem for model strongly correlated electron-systems [PDF]
, 1995 Inspired by earlier work on the band-gap problem in insulators, we reexamine the treatment of strongly correlated Hubbard-type models within density-functional theory.

Properties and detection of spin nematic order in strongly correlated electron systems [PDF]
, 2016 A spin nematic is a state which breaks spin SU(2) symmetry while preserving translational and time reversal symmetries. Spin nematic order can arise naturally from charge fluctuations of a spin stripe state.

Evidence for the Josephson Effect in Quantum Hall Bilayers [PDF]
, 2004 This thesis presents tunneling measurements on bilayer two-dimensional (2D) electrons systems in GaAs/AlGaAs double quantum wells. 2D-2D tunneling is applied here as a probe of the inter-layer correlated quantum Hall state at total Landau level filling

Spin localization, magnetic ordering, and electronic properties of strongly correlated Ln 2 O 3 sesquioxides (Ln=La, Ce, Pr, Nd) [PDF]
, 2018 International audienceLanthanide sesquioxides are strongly correlated materials characterized by highly localized unpaired electrons in the f band. Theoretical descriptions based on standard density functional theory (DFT) formulations are known to be ...

Bosonic spectral function and the electron-phonon interaction in HTSC cuprates [PDF]
, 2010 In this paper we discuss experimental evidence related to the structure and origin of the bosonic spectral function alpha 2F (omega) in high-temperature superconducting (HTSC) cuprates at and near optimal doping.

Conductance of nano-systems with interactions coupled via conduction electrons: effect of indirect exchange interactions [PDF]
, 2006 A nano-system in which electrons interact and in contact with Fermi leads gives rise to an effective one-body scattering which depends on the presence of other scatterers in the attached leads.

Evidence for Luttinger liquid behavior in crossed metallic single-wall nanotubes [PDF]
, 2004 5 pages, 4 figuresExperimental and theoretical results for transport through crossed metallic single-wall nanotubes are presented. We observe a zero-bias anomaly in one tube which is suppressed by a current flowing through the other nanotube.

Effect of nonadiabatic switching of dynamic perturbations in one-dimensional Fermi systems [PDF]
, 2004 We study a two-dimensional (2D) fermionic quantum-field-theoretical model used to model 1D strongly correlated electrons in the presence of a time-dependent impurity that drives the system out of equilibrium.

Spin-charge separation in Aharonov-Bohm rings of interacting electrons [PDF]
, 2003 We investigate the properties of strongly correlated electronic models on a flux-threaded ring connected to semi-infinite free-electron leads. The interference pattern of such an Aharonov-Bohm ring shows sharp dips at certain flux values, determined by ...
