Non-Hermitian formalism and nonlinear physics
Hichem Eleuch, Ingrid Rotter
The non-Hermitian formalism is used at present in many papers for the description of open quantum systems. A special language developed in this field of physics which makes it diff…

ERS approximation for solving Schrödinger's equation and applications
Hichem Eleuch, Michael Hilke
A new technique was recently developed to approximate the solution of the Schroedinger equation. This approximation (dubbed ERS) is shown to yield a better accuracy than the WKB-ap…

Magnus expansion method for two-level atom interacting with few-cycle pulse
Tuguldur Begzjav, Jonathan S. Ben-Benjamin, Hichem Eleuch +3
Using the Magnus expansion to the fourth order, we obtain analytic expressions for the atomic state of a two-level system driven by a laser pulse of arbitrary shape with small puls…
