Room-temperature memristive switching between charge density wave states
R. Venturini, M. Rupnik, J. Gašperlin +7
Control over charge density wave (CDW) states is technologically promising for the development of ultra-efficient memory devices. However, using electrical pulses for non-volatile…
Optical signatures of dynamical excitonic condensates
Alexander Osterkorn, Yuta Murakami, Tatsuya Kaneko +3
We theoretically study dynamical excitonic condensates occurring in bilayers with an imposed chemical potential difference and in photodoped semiconductors. We show that optical sp…
Measuring the ultrafast screening of in photo-excited charge-transfer insulators with time-resolved X-ray absorption spectroscopy
Denis Golez, Eva Paprotzki, Philipp Werner +1
Recent seminal experiments have utilized time-resolved X-ray absorption spectroscopy (XAS) to investigate the ultrafast photo-induced renormalization of the electron interaction ('…
Collective modes and Raman response in TaNiSe
Banhi Chatterjee, Jernej Mravlje, Denis Golež
We explore the collective response in an excitonic insulator phase in TaNiSe using a semirealistic model including relevant lattice and electronic instabilities. We calcula…
Chirped amplitude mode in photo-excited superconductors
Thomas Blommel, Jason Kaye, Yuta Murakami +2
Using a state-of-the-art numerical scheme, we show that the Higgs mode under excitation exhibits chirped oscillations and exponential decay when fluctuations are included. This is…
