Fractional Chern insulators with a non-Landau level continuum limit
David Bauer, Spenser Talkington, Fenner Harper +2
Recent developments in fractional quantum Hall (FQH) physics highlight the importance of studying FQH phases of particles partially occupying energy bands that are not Landau level…
Finite-wavevector Electromagnetic Response in Lattice Quantum Hall Systems
Fenner Harper, David Bauer, T. S. Jackson +1
In a quantum Hall system, the finite-wavevector Hall conductivity displays an intriguing dependence on the Hall viscosity, a coefficient that describes the non-dissipative response…
Strong spin-orbit fields and Dyakonov-Perel spin dephasing in supported metallic films
Nguyen H. Long, Phivos Mavropoulos, David S. G. Bauer +3
Spin dephasing by the Dyakonov-Perel mechanism in metallic films deposited on insulating substrates is revealed, and quantitatively examined by means of density functional calculat…
Probing quantum capacitance in a 3D topological insulator
D. A. Kozlov, D. Bauer, J. Ziegler +6
We measure the quantum capacitance and probe thus directly the electronic density of states of the high mobility, Dirac type of two-dimensional electron system, which forms on the…
Quantum geometry and stability of the fractional quantum Hall effect in the Hofstadter model
T. S. Jackson, David Bauer, Rahul Roy
We study how the stability of the fractional quantum Hall effect (FQHE) is influenced by the geometry of band structure in lattice Chern insulators. We consider the Hofstadter mode…
Spin relaxation and spin Hall transport in 5d transition-metal ultrathin films
Nguyen H. Long, Phivos Mavropoulos, Bernd Zimmermann +3
The spin relaxation induced by the Elliott-Yafet mechanism and the extrinsic spin Hall conductivity due to the skew-scattering are investigated in 5d transition-metal ultrathin fil…
Spin relaxation and the Elliott-Yafet parameter in W(001) ultrathin films: surface states, anisotropy and oscillation effects
Nguyen H. Long, Phivos Mavropoulos, Bernd Zimmermann +4
Using first-principles methods based on density-functional theory we investigate the spin relaxation in W(001) ultrathin films. Within the framework of the Elliott-Yafet theory we…
Thermally activated magnetization reversal in monoatomic magnetic chains on surfaces studied by classical atomistic spin-dynamics simulations
David S. G. Bauer, Phivos Mavropoulos, Samir Lounis +1
We analyze the spontaneous magnetization reversal of supported monoatomic chains of finite length due to thermal fluctuations via atomistic spin-dynamics simulations. Our approach…
