Excitons in WSe2 time-resolved ARPES: particle or oscillation?
Kai Wu, Michele Puppin, Andrea Marini
The time-resolved angle-resolved photoemission spectra of WSe, a paradigmatic transition metal dichalcogenide, are dominated by a transient signal that, after being initially o…

Observation of polaritonic flat-band bound states in the continuum in a 2D magnet
Fuhuan Shen, Jiahao Ren, Zhiyi Yuan +5
Flat-band bound states in the continuum (BICs) are topological states with suppressed group velocity and robustness against radiation loss, offering a powerful platform for the exp…

Theory of coherent phonons coupled to excitons
Enrico Perfetto, Kai Wu, Gianluca Stefanucci
The interaction of excitons with lattice vibrations underlies the scattering from bright to dark excitons as well as the coherent modulation of the exciton energy. Unlike the forme…
