We point out that unidirectional bond-centered charge-density-wave states in cuprates involve electronic order in both s- and d-wave channels, with non-local Coulomb repulsion suppressing the s-wave component. The resulting bond-charge-density wave,

Motivated by recent experiments on BaCuSi2O6, we investigate magnetic excitations and quantum phase transitions of layered dimer magnets with inter-layer frustration. We consider two scenarios, (A) a lattice with one dimer per unit cell and perfect i

For magnets with a fully frustrated inter-layer interaction, we argue that the quantum phase transitions from a paramagnetic to an antiferromagnetic ground state, driven by pressure or magnetic field, are asymptotically three-dimensional, due to inte

Hinsichtlich der Investitions- und Betriebskosten stellt der Einsatz von Sechs-Achs-Knickarmrobotern als Führungskinematik für Zerspanaufgaben ein enormes Potenzial dar. Dieses kann allerdings bislang aufgrund der geringen erzielbaren Arbeitsgenaui

We study electron-phonon interaction in strongly correlated systems where the interplay with electron-electron interactions needs to be taken into account explicitly. We specifically consider cuprate high-temperature superconductors but also investig
