Density matrix and space-time distributions of the electronic density and current at fast pulsed photoemission through a double quantum well
Yu. G. Peisakhovich, A. A. Shtygashev
Within the framework of the density matrix method, general formulas obtained that are convenient for describing fast pulsed photoemission that occurs in a time less than or on the…
Formation of probability density waves and probability current density waves by excitation and decay of a doublet of quasistationary states of a three-barrier heterostructure upon scattering of gaussian wave packets
Yu. G. Peisakhovich, A. A. Shtygashev
A numerical-analytical simulation of scattering by a three-barrier heterostructure of an electronic Gaussian wave packet, the spectral width of which is on the order of the distanc…
Spontaneous decay of artificial atoms in a multi-qubit system
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We consider a one-dimensional chain of N equidistantly spaced noninteracting qubits embedded in an open waveguide. In the frame of single-excitation subspace, we systematically stu…
Waveguide bandgap N-qubit array with a tunable transparency resonance
Ya. S. Greenberg, A. A. Shtygashev, A. G. Moiseev
We study a single photon transmission through 1D N- qubit chain. The qubits are supposed to be identical with equal distance between neighbors. We express the transfer matrix of N-…
Excitation of the collective states in a three-qubit system
Ya. S. Greenberg, A. A. Shtygashev
In the present paper, we have proposed the experimentally achievable method for the characterization of the collective states of qubits in a linear chain. We study temporal dynamic…
