چکیده

در این مقاله، یک پلاسمای ابر یانگ- میلز ناهمسانگرد در دمای متناهی را در نظر می‌گیریم و رسانندگی الکتریکی آن را در حضور یک میدان الکتریکی یکنواخت بررسی می‌کنیم. با اعمال میدان الکتریکی در دو جهت متفاوت، تاثیر شدت میدان الکتریکی، چگالی بار و پارامتر ناهمسانگردی را بر رسانندگی الکتریکی پلاسمای مورد نظر مطالعه می‌کنیم. ابتدا میدان الکتریکی خارجی یکنواخت را در جهت مختصه عرضی x در نظر می‌گیریم ‌و پس از آن میدان الکتریکی خارجی در جهت مختصه طولی z به سیستم اعمال می‌شود. در پایان نتایج به دست آمده در دو جهت مختلف را با یکدیگر مقایسه می‌کنیم. علاوه بر این نتایج به دست آمده با سیاهچاله همسانگرد شوارتزشیلد AdS و مدل غیربحرانی AdS6 نیز مقایسه می‌شود.

چکیده [English]

In this paper, we consider the anisotropic super Yang-Mils plasma at finite temperature and and calculate its conductivity in the presence of a constant electric field. By applying the electric field in two different directions, we study the effect of the electric field, charge density and anisotropy parameter on the electrical conductivity of the plasma. We first consider the constant external electric field in the longitudinal x-direction, and then the external electric field is applied to the system in the longitudinal z- direction. At the end, we compare the results of two different directions with each other. Also, we compare the results with those from isotropic Ads-Schwarzschild black hole and non-critical Ads6 model.
