An edge index for the Quantum Spin-Hall effect
Emil Prodan
Quantum Spin-Hall systems are topological insulators displaying dissipationless spin currents flowing at the edges of the samples. In contradistinction to the Quantum Hall systems…
The edge spectrum of Chern insulators with rough boundaries
Emil Prodan
Chern insulators are periodic band insulators with the property that their projector onto the occupied bands have non-zero Chern number. Chern insulator with a homogeneous boundary…
Band Alignment in Molecular Devices: Influence of Anchoring Group and Metal Work Function
Jian-guo Wang, Emil Prodan, Roberto Car +1
We present periodic Density Functional Theory calculations of the electronic properties of molecular junctions formed by amine-, and thiol-terminated alkane chains attached to two…
Tunneling conductance of amine linked alkyl chains
Emil Prodan, Roberto Car
The tunneling transport theory developed in Phys. Rev. B {\bf 76}, 115102 (2007) is applied to molecular devices made of alkyl chains linked to gold electrodes via amine groups. Us…
Topological quantization of ensemble averages
Emil Prodan
We define the current of a quantum observable and, under well defined conditions, we connect its ensemble average to the index of a Fredholm operator. The present work builds on a…
Long-time electron spin storage via dynamical suppression of hyperfine-induced decoherence in a quantum dot
Wenxian Zhang, N. P. Konstantinidis, V. V. Dobrovitski +3
The coherence time of an electron spin decohered by the nuclear spin environment in a quantum dot can be substantially increased by subjecting the electron to suitable dynamical de…
