Wave function propagation in a two-dimensional paramagnetic semiconductor from an impurity
Josh Wanninger, Gonzalo Ordonez
We simulated modifications to a model of a two-dimensional paramagnetic semiconductor called the half-BHZ model, also known as the QWZ model, and simulated a modified full BHZ mode…
Resonant-State Expansion of the Fano Peak in Open Quantum Systems
Naomichi Hatano, Gonzalo Ordonez
We describe the Fano asymmetry by expanding the transmission amplitude with respect to states with point spectra (discrete eigenstates), including not only bound states but also re…
Impurity-directed Transport within a Finite Disordered Lattice
Bradley Magnetta, Gonzalo Ordonez, Savannah Garmon
We consider a finite, disordered 1D quantum lattice with a side-attached impurity. We study theoretically the transport of a single electron from the impurity into the lattice, at…
Universal electric current of interacting resonant-level models with asymmetric interactions: An extension of the Landauer formula
Akinori Nishino, Naomichi Hatano, Gonzalo Ordonez
We study the electron transport in open quantum-dot systems described by the interacting resonant-level models with Coulomb interactions. We consider the situation in which the qua…
Resonant-state expansion of the Green's function of open quantum systems
Naomichi Hatano, Gonzalo Ordonez
Our series of recent work on the transmission coefficient of open quantum systems in one dimension will be reviewed. The transmission coefficient is equivalent to the conductance o…
Resonant Spectrum Analysis of the Conductance of Open Quantum System and Three Types of Fano Parameter
Keita Sasada, Naomichi Hatano, Gonzalo Ordonez
We explain the Fano peak (an asymmetric resonance peak) as an interference effect involving resonant states. We reveal that there are three types of Fano asymmetry according to the…
