Phonon-assisted transport through suspended carbon nanotube quantum dots
Phonon-assisted transport through suspended carbon nanotube quantum dots
2014/5/28
Motivated by several recent experiments, we investigate phonon-assisted electronic transport through suspended carbon nanotube quantum dots including electron-electron, electron-phonon, and spin-orbit...
Signatures of Wigner molecule formation in interacting Dirac fermion quantum dots
Signatures of Wigner molecule formation Dirac fermion quantum dots
2010/11/18
We study N interacting massless Dirac fermions confined in a two-dimensional quantum dot.
Physical realizations of this problem include a graphene monolayer and the surface state of a strong topologi...
Synchronized single electron emission from dynamical quantum dots
Synchronized single electron emission dynamical quantum dots
2010/11/22
We study synchronized quantized charge pumping through several dynamical quantum dots (QDs) driven by a single time modulated gate signal. We show that the main obstacle for synchronization being the ...
A Layered Architecture for Quantum Computing Using Quantum Dots
A Layered Architecture Quantum Computing Quantum Dots
2010/11/8
We address the challenge of designing a quantum computer architecture with a layered framework that is modular and facilitates fault-tolerance. The framework is flexible and could be used for analysi...
Hybridization and spin decoherence in heavy-hole quantum dots
Hybridization spin decoherence heavy-hole quantum dots
2010/10/27
We theoretically investigate the spin dynamics of a heavy hole con ned to a III-V semiconductor quantum dot interacting with a narrowed nuclear-spin bath. We show that band hybridization leads to an e...
In this work, the exchange energy J for a system of two laterally-coupled quantum dots, each one with an electron, is calculated analytically and in a detailed form, considering them as hydrogen-like ...
Control of the direction and rate of nuclear spin flips in InAs quantum dots using detuned optical pulse trains
nuclear spin flips InAs quantum dots detuned optical pulse trains
2010/4/8
We find that detuning an optical pulse train from electronic transitions in quantum dots controls the direction of nuclear spin flips. The optical pulse train generates electron spins that precess abo...
