TL;DR: In this paper, the interplay between different types of disorder and electron-electron interactions in graphene planes is studied by means of renormalization group techniques, and the low-temperature properties of the system are determined by fixed points where the strength of the interactions remains finite, as in one-dimensional Luttinger liquids.

TL;DR: This work uncovers the different mechanisms that give rise to photocurrent generation in graphene on a polar substrate and finds an enhancement of the photoresponse when the light excites bulk or surface phonons of the SiO2 substrate.

TL;DR: In this paper, a spectrally resolved study of the graphene photoresponse for mid-infrared light was performed by measuring spatially resolved photocurrent over a broad frequency range (1000−1600 cm −1 ).

TL;DR: In this paper, the self-energy of the electronic propagator due to the presence of Holstein polarons within the first Born approximation was obtained. But the effects due to Holstein phonons are negligible and that the Boltzmann approach which does not include inter-band transition and can thus not treat optical phonons due to their high energy of $\hbar\omega_0\sim 0.2$eV, remains valid.

TL;DR: In this paper, the effect of electron-electron interactions in the electronic properties of a biased graphene bilayer was studied and it was shown that due to the unusual topology of the Fermi surface, electron and electron interactions are greatly enhanced.
