Quantum transport regimes in quartic dispersion materials with Anderson disorder
Mustafa Polat, Hazan Özkan, Hâldun Sevinçli
Mexican-hat-shaped quartic dispersion manifests itself in certain families of single-layer twodimensional hexagonal crystals such as compounds of groups III-VI and groups IV-V as w…

Atomic Collapse in Disordered Graphene Quantum Dots
Mustafa Polat, A. D. Güçlü
In this paper, we numerically study a Coulomb impurity problem for interacting Dirac fermions restricted in disordered graphene quantum dots. In the presence of randomly distribute…

Collapse of the vacuum in hexagonal graphene quantum dots: a comparative study between the tight-binding and the mean-field Hubbard models
Mustafa Polat, Hâldun Sevinçli, A. D. Güçlü
In this paper, we perform a systematic study on the electronic, magnetic, and transport properties of the hexagonal graphene quantum dots (GQDs) with armchair edges in the presence…
