Finite width of the sonic event horizon and grey body Hawking radiation
Y. Vinish, V. Fleurov
Finite width of the analog event horizon is determined by the nonlinearity length in the Kerr nonlinear optical system, which is discussed here, or by the healing length in Bose-Ei…
Nonlocality and fluctuations near the optical analog of a sonic horizon
S. Bar-Ad, R. Schilling, V. Fleurov
We consider the behavior of fluctuations near the sonic horizon and the role of the nonlocality of interaction (nonlinearity) on their regularization. The nonlocality dominates if…
The Nature of the magnetism-promoting hole state in the prototype magnetic semiconductor GaAs: Mn
V. Fleurov, K. Kikoin, A. Zunger
Recent experiments [1] suggest that the ferromagnetism (FM) in GaAs: Mn is determined by the impurity band rather than holes in the valence band. We discuss here the physical mecha…
Dynamics of fluctuations in an optical analog of the Laval nozzle
I. Fouxon, O. V. Farberovich, S. Barad +1
Using the analogy between the description of coherent light propagation in a medium with Kerr nonlinearity by means of nonlinear Schrödinger equation and that of a dissipationless…
Electronic structure of noble metal impurities in semiconductors: Cu in GaP
O. V. Farberovich, A. Yaresko, K. Kikoin +1
A numerical method for calculation of the electronic structure of transition metal impurities in semiconductors based on the Green function technique is developed. The electronic s…
Temporal dynamics of tunneling. Hydrodynamic approach
G. Dekel, V. Fleurov, A. Soffer +1
We use the hydrodynamic representation of the Gross -Pitaevskii/Nonlinear Schroedinger equation in order to analyze the dynamics of macroscopic tunneling process. We observe a tend…
