Emission characteristics of laser-driven dissipative coupled-cavity systems
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden +1
We consider a laser-driven and dissipative system of two coupled cavities with Jaynes-Cummings nonlinearity. In particular, we investigate both incoherent and coherent laser drivin…
The coherence-incoherence crossover and the mass-renormalization puzzles in Sr2RuO4
Jernej Mravlje, Markus Aichhorn, Takashi Miyake +3
We calculate the electronic structure of Sr2RuO4, treating correlations in the framework of dynamical mean-field theory. The approach successfully reproduces several experimental r…
Variational cluster approach for strongly correlated lattice bosons in the superfluid phase
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
We extend the variational cluster approach to deal with strongly correlated lattice bosons in the superfluid phase. To this end, we reformulate the approach within a pseudoparticle…
Approximate solution of variational wave functions for strongly correlated systems: Description of bound excitons in metals and insulators
Balazs Hetenyi
An approximate solution scheme, similar to the Gutzwiller approximation, is presented for the Baeriswyl and the Baeriswyl-Gutzwiller variational wavefunctions. The phase diagram of…
On k-Convex Polygons
Oswin Aichholzer, Franz Aurenhammer, Erik D. Demaine +3
We introduce a notion of -convexity and explore polygons in the plane that have this property. Polygons which are \mbox{-convex} can be triangulated with fast yet simple algo…
Excitations in disordered bosonic optical lattices
Michael Knap, Enrico Arrigoni, Wolfgang von der Linden
Spectral excitations of ultracold gases of bosonic atoms trapped in one dimensional optical lattices with disorder are investigated by means of the variational cluster approach app…
