Pyramidal core-shell quantum dot under applied electric and magnetic fields

temperature effects of an asymmetry quantum dot qubit under an applied electric field

we study the eigenenergies and eigenfunctions of the ground and first excited states (gfes) of an electron strongly coupled to the lo-phonon in an asymmetry quantum dot (aqd) under an applied electric field by using a variational method of the pekar type (vmpt). this aqd two-level system may be viewed as a single qubit. when the electron is in the superposition state (ss) of the gfes, the effec...

Core-Shell-Structured Copolyaniline-Coated Polymeric Nanoparticle Suspension and Its Viscoelastic Response under Various Electric Fields

Semi-conducting poly(n-methylaniline) (PNMA)-coated poly(methyl methacrylate) (PMMA) composite nanoparticles were synthesized using cross-linked and grafted PMMA particles as a core, and then, the PNMA shell was coated via chemical oxidative polymerization on the surface of modified PMMA nanoparticles. Their electroresponsive electrorheological characteristics when dispersed in silicone were co...

Voltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...

Temperature effects of an asymmetry quantum dot qubit under an applied electric field

We study the eigenenergies and eigenfunctions of the ground and first excited states (GFES) of an electron strongly coupled to the LO-phonon in an asymmetry quantum dot (AQD) under an applied electric field by using a variational method of the Pekar type (VMPT). This AQD two-level system may be viewed as a single qubit. When the electron is in the superposition state (SS) of the GFES, the effec...
