Universality in the Energy Spectrum of Medium-Sized Quantum Dots
Alexander Odriazola, Alain Delgado, Augusto González
In a two-dimensional parabolic quantum dot charged with electrons, Thomas-Fermi theory states that the ground-state energy satisfies the following non-trivial relation: $E_{gs}…
Excitonic States in Medium-Size Quantum Dots
Alexander Odriazola, Alain Delgado, Augusto Gonzalez
In a quantum dot with dozens of electrons, an approximation beyond Tamm-Dankoff is used to construct the quantum states with an additional electron-hole pair, i.e. the "excitonic"…
Inelastic light scattering by electronic excitations in artificial atoms
Alain Delgado, Augusto Gonzalez, D. J. Lockwood
In the paper, we present theoretical calculations of the cross section for inelastic light scattering by electronic excitations in a quantum dot charged with 42 electrons. The many…
Selection and jump rules in electronic Raman scattering from GaAs/Al_{x}Ga_{1-x}As artificial atoms
Alain Delgado, Augusto Gonzalez, D. J. Lockwood +1
A theoretical description of electronic Raman scattering from GaAs/Al_{x}Ga_{1-x}As artificial atoms under the influence of an external magnetic field is presented. Raman spectra w…
Electronic Raman scattering in quantum dots revisited
Alain Delgado, Augusto Gonzalez, David J. Lockwood
We present theoretical results concerning inelastic light (Raman) scattering from semiconductor quantum dots. The characteristics of each dot state (whether it is a collective or s…
Cyclotron resonance and inelastic light scattering in semiconductor quantum dots
Augusto Gonzalez, Alain Delgado
A set of theoretical results on infrared absorption and inelastic (Raman) scattering of light in semiconductor quantum dots is reviewed. When it is possible, qualitative comparison…
