Resonant excitations via low frequency pumping in driven magnon systems
Jan Mathis Giesen, Alexandre Abbass Hamadeh, Imke Schneider +2
We analyse resonant excitations of ferromagnetic magnons via microwave pumping using Floquet theory. Special focus is put on driving frequencies that are below the corresponding ma…
Anyonic phase transitions in the 1D extended Hubbard model with fractional statistics
Martin Bonkhoff, Kevin Jägering, Shijie Hu +3
We study one-dimensional (1D) lattice anyons with extended Hubbard interactions at unit filling using bosonization and numerical simulations. The behavior can be continuously tuned…
Dissipative Dicke time crystals: an atoms' point of view
Simon B. Jäger, Jan Mathis Giesen, Imke Schneider +1
We develop and study an atom-only description of the Dicke model with time-periodic couplings between atoms and a dissipative cavity mode. The cavity mode is eliminated giving rise…
Nonlinear effects on charge fractionalization in critical chains
Flávia B. Ramos, Rodrigo G. Pereira, Sebastian Eggert +1
We investigate the generic transport in a one-dimensional strongly correlated fermionic chain beyond linear response. Starting from a Gaussian wave packet with positive momentum on…
