• #### Antilocalization of Coulomb Blockade in a Ge/Si Nanowire ﻿

(American Physical Society (APS), 2014)
The distribution of Coulomb blockade peak heights as a function of magnetic field is investigated experimentally in a Ge/Si nanowire quantum dot. Strong spin-orbit coupling in this hole-gas system leads to antilocalization ...
• #### Carbon Nanotubes for Coherent Spintronics ﻿

(Elsevier Science Limited, 2010)
Carbon nanotubes bridge the molecular and crystalline quantum worlds, and their extraordinary electronic, mechanical and optical properties have attracted enormous attention from a broad scientific community. We review ...
• #### Electron–Nuclear Interaction in $^{13}C$ Nanotube Double Quantum Dots ﻿

(Nature Publishing Group, 2009)
For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a dominant source of unwanted spin decoherence or, if controlled effectively, a resource enabling storage and retrieval of quantum ...
• #### Giant spin rotation under quasiparticle-photoelectron conversion: Joint effect of sublattice interference and spin-orbit coupling ﻿

(American Physical Society (APS), 2009)
Spin- and angular-resolved photoemission spectroscopy is a basic experimental tool for unveiling spin polarization of electron eigenstates in crystals. We prove, by using spin-orbit coupled graphene as a model, that ...
• #### Hole Spin Relaxation in Ge-Si Core-Shell Nanowire Qubits ﻿

(Nature Publishing Group, 2012)
Controlling decoherence is the biggest challenge in efforts to develop quantum information hardware. Single electron spins in gallium arsenide are a leading candidate among implementations of solid-state quantum bits, but ...
• #### Relaxation and Dephasing in a Two-Electron $^{13}C$ Nanotube Double Quantum Dot ﻿

(American Physical Society, 2009)
We use charge sensing of Pauli blockade (including spin and isospin) in a two-electron $^{13}C$ nanotube double quantum dot to measure relaxation and dephasing times. The relaxation time $T_1$ first decreases with a ...
• #### Spin-orbit effects in carbon-nanotube double quantum dots ﻿

(American Physical Society (APS), 2010)
We study the energy spectrum of symmetric double quantum dots in narrow-gap carbon nanotubes with one and two electrostatically confined electrons in the presence of spin-orbit and Coulomb interactions. Compared to GaAs ...
