Unconventional plasmon dynamics due to strong correlations in SrRuO
Juraj Krsnik, Dino Novko, Fabian B. Kugler +2
Plasmon modes, their dispersion, and the onset of damping when approaching the electron-hole continuum are well understood when electron correlations are weak. However, we know lit…

Excitations across the equilibrium and photoinduced `hidden' states of magnetoresistive manganites
Shiyu Fan, Feng Jin, Taehun Kim +16
"Hidden" phases, generated using ultrafast laser pulses (few hundred femtoseconds), with properties distinct from thermodynamic equilibrium, are appealing for technologies because…

Polarons with arbitrary nonlinear electron-phonon interaction
Stefano Ragni, Tomislav MiÅ¡kiÄ, Thomas Hahn +5
We develop an exact computational method based on numerical X-propagators for solving polaron models with arbitrary nonlinear couplings of local vibration modes to the electron den…
