Pawel Hawrylak (Department of Physics, University of Ottawa, Canada): Interacting electrons in 2D materials
Effects of electron-electron interactions in 2D materials will be discussed: transition metal dichalcogenides (TMDCs) [1], graphene [2], artificial graphene [3], and lateral gated quantum dots [4]. We start with an ab-initio based tight-binding model allowing for the understanding of the K and Q valleys, band nesting, Lande and Zeeman Valley effects, and topology on the exciton spectrum [5]. Next, we discuss resonant exciton-phonon interaction and its effect on exciton stability [6]. We follow with a discussion of broken symmetry Valley Polarised Electron Gas states of interacting electrons in bulk [7] and in gated lateral quantum dots [4]. We next turn to quantum simulators of strongly correlated phases in synthetic quantum Hall systems [3] and finish with a brief discussion of Anderson resonances in the Fock space resulting in the breakdown of spectral functions [8].
