Far infrared giant dipole resonances in neutral quantum dots
نویسندگان
چکیده
A resonance behaviour of the far infrared absorption probability at a frequency∼ N1/4 is predicted for clusters of N electron-hole pairs (2 ≤ N ≤ 110) confined in disk-shaped quantum dots. For radially symmetric dots, the absorption is dominated by a Giant Dipole Resonance, which accounts for more than 98 % of the energy-weighted photoabsorption sum rule. PACS numbers: 71.35.Ee, 78.66.-w

Double-resonance spectroscopy of InAsÕGaAs self-assembled quantum dots
We present far-/near-infrared double resonance measurements of self-assembled InAs/GaAs quantum dots. The far-infrared resonance is unambiguously associated with a bound-bound intraband transition in the neutral dots. The results show that the interband photoluminescence ~PL! lines originate from conduction levels with successively increasing in-plane quantum numbers. We determine the confineme...
متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...

متن کاملCalculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics
In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...
متن کاملModulation of the Aharonov–Bohm effect in type-II II–V ZnSe: Te quantum dots by a far-infrared laser
We present magneto-photoluminescence of a ZnTe/ZnSe multilayer structure in which the clustering of Te atoms results in the formation of columns of type-II ZnSe:Te quantum dots. This unique geometry permits the observation of strong Aharonov–Bohm oscillations in both the emission energy and peak intensity with increasing magnetic field. Furthermore, far-infrared optically detected resonance tec...
