Two distinct ballistic processes in graphene at Dirac point
M. Lewkowicz, B. Rosenstein, D. Nghiem
The dynamical approach is applied to ballistic transport in mesoscopic graphene samples of length L and contact potential U. At times shorter than both relevant time scales, the fl…
Alkanethiol-Based Single-Molecule Transistors
Chun-Lan Ma, Diu Nghiem, Yu-Chang Chen
The transport properties of unsubstituted and amino-substituted butanethiol molecules sandwiched between Au electrodes are investigated by using first-principles approaches. New st…
Energy Level Statistics of Quantum Dots
Chien-Yu Tsau, Diu Nghiem, Robert Joynt +1
We investigate the charging energy level statistics of disordered interacting electrons in quantum dots by numerical calculations using the Hartree approximation. The aim is to obt…
Exact solution of qubit decoherence models by a transfer matrix method
Diu Nghiem, Robert Joynt
We present a new method for the solution of the behavior of an ensemble of qubits in a random time-dependent external field. The forward evolution in time is governed by a transfer…
