　　腔光力系統(tǒng)是當(dāng)前實(shí)驗(yàn)和理論的研究重點(diǎn),近年來取得了令人矚目的巨大進(jìn)步。典型的腔光力系統(tǒng)包括一個(gè)光學(xué)諧振腔和一個(gè)微機(jī)械腔或納米機(jī)械腔,它可以使光學(xué)的自由度與機(jī)械的自由度耦合,也可以使腔場與機(jī)械振子相互調(diào)制。通常將二能級(jí)原子加入到光力系統(tǒng)中可以提高腔場與振子之間的耦合強(qiáng)度,這直接會(huì)豐富光力系統(tǒng)中的各種非線性效應(yīng),有助于研究光力系統(tǒng)中的諸如光力誘導(dǎo)透明(OMIT)等量子效應(yīng)。在本文中,我們以光力誘導(dǎo)透明為主,研究腔光力混合系統(tǒng)中的量子非線性效應(yīng)。本文的主要包括六章,其中第3章到第5章是我們的主要工作,第6章是本文的總結(jié)和討論。我們?cè)诘谝徽陆榻B了腔光力系統(tǒng)的背景及其研究進(jìn)展。尤其簡單回顧了光力誘導(dǎo)透明以及Fano共振現(xiàn)象的基本研究情況。第二章,我們介紹了腔光力系統(tǒng)的基本概念和相關(guān)知識(shí)。首先介紹了機(jī)械振子以及輻射壓,進(jìn)而引入光力系統(tǒng)以及相關(guān)的實(shí)驗(yàn)進(jìn)度。然后我們?cè)敿?xì)介紹了光力系統(tǒng)的動(dòng)力學(xué)描述,主要包括基本哈密頓量、光力耦合、量子朗之萬方程、輸入輸出關(guān)系等。最后,我們著重介紹了與我們主要工作密切相關(guān)光力誘導(dǎo)透明以及Fano共振現(xiàn)象。第三章,我們研究了由N個(gè)腔和原子組成的光力系統(tǒng)中的透明現(xiàn)象。我們發(fā)現(xiàn)...
