Superstructure evolution of tellurium atoms on Au(111) surface at different coverages
Jiaqi Guan, Xiaochun Huang, Shuyuan Zhang +4
We systematically investigated the superstructure evolution of Te atoms on Au(111) substrate at different coverages. As revealed by low temperature scanning tunneling microscopy an…
Quantum oscillations in graphene in the presence of disorder and interactions
Pallab Goswami, Xun Jia, Sudip Chakravarty
Quantum oscillations in graphene is discussed. The effect of interactions are addressed by Kohn's theorem regarding de Haas-van Alphen oscillations, which states that electron-elec…
Dissipation and criticality in the lowest Landau level of graphene
Xun Jia, Pallab Goswami, Sudip Chakravarty
The lowest Landau level of graphene is studied numerically by considering a tight-binding Hamiltonian with disorder. The Hall conductance and the longitudinal condu…
Entanglement entropy and multifractality at localization transitions
X. Jia, A. R. Subramaniam, I. A. Gruzberg +1
The von Neumann entanglement entropy is a useful measure to characterize a quantum phase transition. We investigate the non-analyticity of this entropy at disorder-dominated quantu…
Quantum Hall plateau transition in the lowest Landau level of disordered graphene
Pallab Goswami, Xun Jia, Sudip Chakravarty
We investigate, analytically and numerically, the effects of disorder on the density of states and on the localization properties of the relativistic two dimensional fermions in th…
