Breather mode in the many-electron dynamics of semiconductor quantum wells
F. Haas, G. Manfredi, P. K. Shukla +1
We demonstrate the existence of a novel breather mode in the self-consistent electron dynamics of a semiconductor quantum well. A non-perturbative variational method based on quant…
Magnetization reversal in isolated and interacting single-domain nanoparticles
H. Kesserwan, G. Manfredi, J. -Y. Bigot +1
Computational and experimental results on the thermally-induced magnetization reversal in single-domain magnetic nanoparticles are reported. The simulations are based on the direct…
Spin-dependent dipole excitation in alkali-metal nanoparticles
Yue Yin, Paul-Antoine Hervieux, Rodolfo A. Jalabert +3
We study the spin-dependent electronic excitations in alkali-metal nanoparticles. Using numerical and analytical approaches, we focus on the resonances in the response to spin-depe…
Autoresonant control of the many-electron dynamics in nonparabolic quantum wells
G. Manfredi, P. -A. Hervieux
The optical response of nonparabolic quantum wells is dominated by a strong peak at the plasmon frequency. When the electrons reach the anharmonic regions, resonant absorption beco…
