A self-energy-functional approach is applied to construct cluster approximations for correlated lattice models. It turns out that the cluster-perturbation theory [Phys. Rev. Lett. 84, 522 (2000)]]â€¦ (More)

Based on the self-energy-functional approach proposed recently [M. Potthoff, Eur. Phys. J. B 32, 429 (2003)], we present an extension of the cluster-perturbation theory to systems with spontaneouslyâ€¦ (More)

The superfluid to Mott insulator transition in cavity polariton arrays is analyzed using the variational cluster approach, taking into account quantum fluctuations exactly on finite length scales.â€¦ (More)

We calculate the electronic structure of Sr(2)RuO(4), treating correlations within dynamical mean-field theory. The approach successfully reproduces several experimental results and explains the keyâ€¦ (More)

We present a simulation modeling chain for nano-scaled III/V quantum-well MISFETs. Our methods are based on physical rather than empirical modeling, which allows to obtain predictive simulationâ€¦ (More)

â€“ We study the quantum transition from an antiferromagnet to a superconductor in a model for electronand hole-doped cuprates by means of a variational cluster perturbation theory approach. In bothâ€¦ (More)

One promising setting to explore these issues is the iron chalcogenides, which host the highest Tc among the FeSCs (65 K, as determined by the onset of the Meissner effect [1]). There is an emergingâ€¦ (More)

Recent experiments (angle-resolved photoemission spectroscopy and Raman) suggest the presence of two distinct energy gaps in high-temperature superconductors (HTSC), exhibiting different dopingâ€¦ (More)

We review results obtained with a recently proposed variational cluster approach (VCA) for the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the high-TC cuprates.â€¦ (More)

We discover that hcp phases of Fe and Fe(0.9)Ni(0.1) undergo an electronic topological transition at pressures of about 40 GPa. This topological change of the Fermi surface manifests itself throughâ€¦ (More)
