TL;DR: A dynamical view on the Dirac cone is presented by time- and angle-resolved photoemission spectroscopy to show the quasi-instant thermalization of the electron gas to a temperature of ≈2000 K, and to disentangle the subsequent decay into excitations of optical phonons and acoustic phonons.

TL;DR: This work uses tr-ARPES to demonstrate long-lived population inversion in bilayer graphene and proposes a microscopic model for these observations and speculate that an enhancement of both the pump photon energy and the pump fluence may further increase this lifetime.

TL;DR: In this article, the authors proposed a microscopic model for population inversion across the Dirac point in bilayer graphene and showed that an enhancement of pump photon energy and pump fluence may further increase the lifetime.

TL;DR: The Artemis facility for ultrafast XUV science is constructed around a high average power carrier-envelope phasestabilised system, which is used to generate tuneable pulses across a wavelength range spanning the UV to the far infrared, few-cycle pulses at 800nm and short pulses of XUV radiation produced through high harmonic generation as discussed by the authors.

TL;DR: The experiments demonstrate how highly featured rotational spectra can be obtained from an extremely cold environment where only the lowest rotational energy states are initially populated.
