Characterization of helical states in semiconductor quantum wells using quantum information quantities
Natalia Giovenale, Omar Osenda
The information content of one-electron bulk and edge states in semiconductor quantum wells is calculated in the inverted regime, where edge states, topologically protected, are re…
Study of the transition from resonance to bound states in quantum dots embedded on a nanowire using the method
Natalia Giovenale, Omar Osenda}
We study the band structure of semiconductor nanowires with quantum dots embedded in them. The band structure is calculated using the Rayleigh-Ritz variational method. We consider…
Excitonic states in spherical layered quantum dots
Mariano Garagiola, Omar Osenda
he properties of excitons formed in spherical quantum dots are studied using the method within the Hartree approximation. The spherical quantum dots con…
Fast optical control of a coded qubit in a triple quantum dot
Diego S. Acosta Coden, Sergio S. Gomez, Rodolfo H. Romero +2
In this work, we study strategies for the optical control, within the dipole approximation, of a qubit encoded in the three-electron states of a triple quantum dot. The system is d…
Resonance states in a cylindrical quantum dot with an external magnetic field
Alba Y Ramos, Omar Osenda
Bound and resonance states of quantum dots play a significant role in photo-absorption processes. In this work, we analyze a cylindrical quantum dot, its spectrum and, in particula…
Near-threshold properties of the electronic density of layered quantum-dots
Alejandro Ferrón, Pablo Serra, Omar Osenda
We present a way to manipulate an electron trapped in a layered quantum dot based on near-threshold properties of one-body potentials. We show that potentials with a simple global…
