Many-body theory of the neutralization of strontium ions on gold surfaces

M. Pamperin, F. X. Bronold, H. Fehske

Motivated by experimental evidence for mixed-valence correlations affecting the neutralization of strontium ions on gold surfaces we set up an Anderson-Newns model for the Sr:Au sy…

Exciton formation in strongly correlated electron-hole systems near the semimetal-semiconductor transition

B Zenker, D Ihle, F X Bronold +1

The region surrounding the excitonic insulator phase is a three-component plasma composed of electrons, holes, and excitons. Due to the extended nature of the excitons, their prese…

Spectral and Entanglement Properties of the Bosonic Haldane Insulator

Satoshi Ejima, Florian Lange, Holger Fehske

We discuss the existence of a nontrivial topological phase in one-dimensional interacting systems described by the extended Bose-Hubbard model with a mean filling of one boson per…

Comparative density-matrix renormalization group study of symmetry-protected topological phases in spin-1 chain and Bose-Hubbard models

Satoshi Ejima, Holger Fehske

We reexamine the one-dimensional spin-1 model with on-site uniaxial single-ion anisotropy as to the appearance and characterization of the symmetry-protected topological Hald…

Fate of the excitonic insulator in the presence of phonons

B. Zenker, H. Fehske, H. Beck

The influence of phonons on the formation of the excitonic insulator has hardly been analyzed so far. Recent experiments on , 1-, and $\rm TmSe_{0.45…

Route to chaos in optomechanics

L. Bakemeier, A. Alvermann, H. Fehske

We establish the emergence of chaotic motion in optomechanical systems. Chaos appears at negative detuning for experimentally accessible values of the pump power and other system p…
