The influence of proximity effects in inhomogeneous electronic states
Matthias Mayr
We describe the high-temperature superconductor LaSrCuO in the underdoped regime in terms of a mixed-phase model, which consists of superconducting clusters embedde…
Domain-wall excitons and optical conductivity in one-dimensional Wigner lattices
Matthias Mayr, Peter Horsch
Motivated by the recent finding that doped edge-sharing Cu-O chain compounds like NaCuO and NaCuO are realizations of one-dimensional Wigner crystals, we…
The One-Particle Spectral Function and the Local Density of States in a Phenomenological Mixed-Phase Model for High-Temperature Superconductors
M. Mayr, A. Gonzalez, A. Moreo +1
The dynamical properties of a recently introduced phenomenological model for high temperature superconductors are investigated. In the clean limit, it was observed that none of the…
Wigner crystallization in Na(3)Cu(2)O(4) and Na(8)Cu(5)O(10) chain compounds
P. Horsch, M. Sofin, M. Mayr +1
We report the synthesis of novel edge-sharing chain systems Na(3)Cu(2)O(4) and Na(8)Cu(5)O(10), which form insulating states with commensurate charge order. We identify these syste…
Helicoidal magnetic order in a clean copper oxide spin chain compound
L. Capogna, M. Mayr, P. Horsch +6
We report susceptibility, specific heat, and neutron diffraction measurements on NaCuO, a spin-1/2 chain compound isostructural to LiCuO, which has been extensively…
Phase Diagram of a Model for Diluted Magnetic Semiconductors Beyond Mean-Field Approximations
Gonzalo Alvarez, Matthias Mayr, Elbio Dagotto
A lattice spin-fermion model for diluted magnetic semiconductors (DMS) is investigated numerically, improving on previously used mean-field (MF) approximations. Curie temperatures…
Explanation of Giant Cluster Coexistence in Doped Manganites and Other Compounds
Adriana Moreo, Matthias Mayr, Adrian Feiguin +2
Computational studies show the generation of large coexisting metallic and insulating clusters with equal electronic density in models for manganites. The clusters are induced by d…
A-type Antiferromagnetic and C-type Orbital-Ordered State in LaMnO Using Cooperative Jahn-Teller Phonons
Takashi Hotta, Seiji Yunoki, Matthias Mayr +1
The effect of Jahn-Teller phonons on the magnetic and orbital structure of LaMnO is investigated using a combination of relaxation and Monte Carlo techniques on three-dimension…
