Distinct spin and orbital dynamics in SrRuO
H. Suzuki, L. Wang, J. Bertinshaw +13
The unconventional superconductor SrRuO has long served as a benchmark for theories of correlated-electron materials. The determination of the superconducting pairing mecha…
Cluster Dynamical Mean Field analysis of the Mott transition
O. Parcollet, G. Biroli, G. Kotliar
We investigate the Mott transition using a cluster extension of dynamical mean field theory (DMFT). In the absence of frustration we find no evidence for a finite temperature Mott…
Pseudogap opening and formation of Fermi arcs as an orbital-selective Mott transition in momentum space
M. Ferrero, P. S. Cornaglia, L. De Leo +3
We present an approach to the normal state of cuprate superconductors which is based on a minimal cluster extension of dynamical mean-field theory. Our approach is based on an effe…
Electronic Structure Calculations with Dynamical Mean-Field Theory: A Spectral Density Functional Approach
G. Kotliar, S. Y. Savrasov, K. Haule +3
We present a review of the basic ideas and techniques of the spectral density functional theory which are currently used in electronic structure calculations of strongly-correlated…
Quantum Fluctuations of a Nearly Critical Heisenberg Spin Glass
A. Georges, O. Parcollet, S. Sachdev
We describe the interplay of quantum and thermal fluctuations in the infinite-range Heisenberg spin glass. This model is generalized to SU(N) symmetry, and we describe the phase di…
Interaction-induced adiabatic cooling and antiferromagnetism of cold fermions in optical lattices
F. Werner, O. Parcollet, A. Georges +1
We propose an interaction-induced cooling mechanism for two-component cold fermions in an optical lattice. It is based on an increase of the ``spin'' entropy upon localisation, an…
