Optical remote control of a charge qubit
Ted S. Santana, Francisco A. G. Almeida
Both the electron transport-based qubits, implemented through double quantum dots, and the sources of indistinguishable single-photons like self-assembled quantum dots are strong c…
Mott Insulator to Superfluid Phase Transition in Bravais Lattices via the Jaynes-Cummings-Hubbard Model
C. B. Gomes, A. M. C. Souza, F. A. G. Almeida
The Properties of the Mott insulator to superfluid phase transition are obtained through the fermionic approximation in the Jaynes-Cummings-Hubbard model on linear, square, SC, FCC…
The influence of the Kerr effect in Mott insulator to superfluid transition from the point of view of the Jaynes-Cummings-Hubbard model
C. B. Gomes, F. A. G. Almeida, A. M. C. Souza
We have studied the Jaynes-Cummings-Hubbard model for a chain with the Kerr effect (nonlinear optical effect) through fermionic approximation. We have observed that the Kerr effec…
Thermal entanglement witness for materials with variable local spin lengths
Andre M. C. Souza, Francisco A. G. Almeida
We show that the thermal entanglement in a spin system using only magnetic susceptibility measurements is restricted to the insulator materials. We develop a generalization of the…
