چکیده
A theoretical novel model is investigated that describes the dynamic effects of microelongation processes an exciting semiconductor medium. The influence magnetic field for optically excited medium taken into consideration according to photothermal transport characteristics. governing equations were derived during electronic (ED) and thermoelastic (TED) deformation when parameters account. interference between thermal-magnetic-microelongat-plasma-mechanical waves investigated. dimensionless expressions are utilized solve main harmonic wave technique in two-dimensional (2D) deformation. complete solutions physical obtained some conditions on outer surface. microelongated this investigation was checked by comparing it with previous studies. numerical simulation distributions graphically displayed silicon (Si) material used. impact various factors such as field, thermal memory effect, propagations fields discussed.

Spontaneously excited pulses in an optically driven semiconductor laser.
In optically injected semiconductor lasers, intrinsic quantum noise alone, namely, the spontaneous emission and the shot noise, are capable of exciting intensity multipulses from a steady state operation. Noisy lasers exhibit self-pulsations in the locking region of the corresponding deterministic system. The interpulse time statistics are studied in parameter regions near k-homoclinic (Shilnik...

The rouge waves in an optically injected semiconductor lasers are receiving a lot of interest. In this work, the generating and controlling of the rogue waves in semiconductor lasers have been investigated. For this purpose, the laser’s rate equations are solved numerically in a specified time interval, then the field amplitude and the intensity versus time are calculated and analyzed. To solve...
متن کاملInfluence of the magnetic field on the thermal condensation
The neutral atomic interstellar medium (HI) is well known to be strongly magnetized. Since HI is a 2-phase medium the questions arise of what is the effect of the magnetic field on a 2-phase medium, how magnetic field affects thermal instability ? Here we summarize analytical and numerical results which have been obtained previously to investigate this question.

متن کاملMagnetic dichroism from optically excited quantum well states.
We demonstrate magnetic dichroism from optically excited states in two-photon photoemission. Using ultrathin cobalt films grown on Cu(001), we observe unoccupied quantum well states which give rise to a sizable intensity change in photoemission under magnetization reversal. The simultaneous comparison of both circular and linear magnetic dichroism in the same system permits us to check fundamen...
