Anomalous dynamical energy flows via nonlinear phononics in spin-Peierls chains
Jakob Dolgner, Dirk Manske, James K. Freericks +1
We investigate the nonequilibrium spin-phonon dynamics and energy cascades in a strongly dimerized spin-Peierls chain using a multi-tiered nonlinear phononics architecture. To bypa…
Detecting superconductivity out-of-equilibrium
Sebastian Paeckel, Benedikt Fauseweh, Alexander Osterkorn +3
Recent pump-probe experiments on underdoped cuprates and similar systems suggest the existence of a transient superconducting state above . This poses the question ho…
Classification and characterization of nonequilibrium Higgs modes in unconventional superconductors
L. Schwarz, B. Fauseweh, N. Tsuji +8
Recent findings of new Higgs modes in unconventional superconductors require a classification and characterization of the modes allowed by nontrivial gap symmetry. Here we develop…
Coherent Order Parameter Oscillations in the Ground State of the Excitonic Insulator Ta2NiSe5
Daniel Werdehausen, Tomohiro Takayama, Marc Höppner +6
The excitonic insulator is an intriguing electronic phase of quasi-condensed excitons. A prominent candidate is the small bandgap semiconductor Ta2NiSe5, in which excitons are beli…
Photoinduced in-gap excitations in the one-dimensional extended Hubbard model
Hantao Lu, Can Shao, Janez Bonča +2
We investigate the time evolution of optical conductivity in the half-filled one-dimensional extended Hubbard model driven by a transient laser pulse, by using the time-dependent L…
