نقش آثار کوانتومی خلأ در رمبش گرانشی و ساختار سیاه‌چاله‌ها


دانشجویان، پژوهشگران و علاقه‌مندان به شگفتی‌های کیهان؛ دعوتید به یک سفر علمی:
 
 موضوع وبینار:
*«نقش آثار کوانتومی خلأ در رمبش گرانشی و ساختار سیاه‌چاله‌ها»*
 
سخنران:
*آقای دکتر مسلم شفیعی*
 
 چکیده:
نظریه کوانتومی پیش‌بینی می‌کند که خلأ کاملاً خالی نیست و دارای نوسانات و انرژی غیرصفر است. این ویژگی بنیادی، انگیزه‌ای برای بازبینی پاسخ‌های کلاسیک معادلات میدان گرانشی در نسبیت عام فراهم می‌کند. در این چارچوب، آثار کوانتومی خلأ می‌توانند به‌عنوان تصحیحات مؤثر بر هندسه فضازمان در نظر گرفته شوند و منجر به تغییر در ساختار کلاسیک سیاه‌چاله‌ها شوند. یکی از پیامدهای مهم این اصلاحات، امکان ظهور ساختار افق چندلایه است، به‌طوری که به‌جای یک افق رویداد منفرد، سیاه‌چاله می‌تواند دارای دو افق بیرونی و افق درونی باشد. همچنین، در نظر گرفتن اثرات کوانتومی در فرآیند رمبش گرانشی می‌تواند به جلوگیری از تشکیل تکینگی و در نتیجه تشکیل سیاه‌چاله‌های غیرتکین یا منظم تحت شرایط مشخص منجر شود. این نتایج نشان می‌دهند که تصحیحات کوانتومی خلأ نقش مهمی در بازتعریف ساختار هندسی و دینامیکی سیاه‌چاله‌ها در رژیم‌های شدید گرانشی ایفا می‌کنند.
 
 زمان برگزاری:
*چهارشنبه ۱۰ تیر ۱۴۰۵ | ساعت ۱۶:۰۰*
