A device adaptive in ow boundary condition for Wigner equations of quantum transport
Frensley in ow boundary condition Wigner function Resonant tunneling diode
2014/9/26
In this paper, an improved in
ow boundary condition is proposed for Wigner equa-tions in simulating a resonant tunneling diode (RTD), which takes into consideration
the band structure of the device....

time-dependent wavepacket diffusion carrier diffusion coefficient static and dynamic disorder band-like to hopping-type transport
2014/9/24
The time-dependent wavepacket diffusion method for carrier quantum dynamics (Zhong and Zhao 2013J. Chem. Phys.138014111), a truncated version of the stochastic Schrödinger equation/wavefunction a...
Coherent quantum transport in disordered systems: I. The influence of dephasing on the transport properties and absorption spectra on one-dimensional systems

2014/9/24
Excitonic transport in static-disordered one dimensional systems is studied in the presence of thermal fluctuations that are described by the Haken–Strobl–Reineker model. For short times, non-diffusiv...
Computation of electron quantum transport in graphene nanoribbons using GPU

2011/8/30
Abstract: We formulate the problem of efficient transport of a quantum particle trapped in a harmonic potential which can move with a bounded velocity, as a minimum-time problem on a linear system wit...
Conductance through quantum wires with Levy-type disorder: universal statistics in anomalous quantum transport
Conductance through quantum wires Levy-type disorder anomalous quantum transport
2010/11/23
Random processes characterized by density probabilities with a long tail–L´evy-type
processes– have been found in very different phenomena and fields such as biology, economy, and physics.
Theory of quantum transport in Josephson junctions with a ferromagnetic insulator
Theory of quantum Josephson junctions ferromagnetic insulator
2010/10/27
We investigate the Josephson transport through ferromagnetic insulators (FIs) by taking into
account the band structure of FIs explicitly. Using the recursive Green’s function method, we found the fo...
Stochastic webs and quantum transport in superlattices: an introductory review
stochastic webs quantum transport superlattices separatrix chaos
2010/4/7
Stochastic webs were discovered, first by Arnold for multi-dimensional Hamiltonian systems, and later by Chernikov et al. for the low-dimensional case. Generated by weak perturbations, they consist of...
Quantum Transport of Electrons Through a Parallel--Coupled Triple Quantum--Dot Molecule
Electronic transport Quantum dots Quantum interference
2010/9/25
In this article we study the electronic transport through a triple quantum–dot molecule parallel–coupled to leads under a magnetic field. Analytical expressions are obtained for both the conductance a...

The effects of the propagation of particles which have a finite life-time and an
according width in their mass spectrum are discussed in the context of transport descriptions. In the first part the c...
