The phase sensitivity of a fully quantum three-mode nonlinear interferometer

Three-mode nonlinear state truncation – squeezing, quantum correlations and entanglement

corresponds to interaction with external coherent field. We assume here that the nonlinearity constants χ , characterizing three oscillators, are identical. Moreover, interaction strengths between modes 1− 2 and 2− 3 are described by the same parameter ǫ, whereas external excitations in the modes 1 and 3 by α. We show that for weak excitation regime, our model behaves as three–mode nonlinear qu...

a comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy

این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...

Nonlinear strain response of two-mode fiber-optic interferometer.

Experimental and theoretical investigation of a nonlinear response of a two-mode fiber interferometer to axial strain is described. It is discovered that the nonlinearity dramatically increases as the wavelength approaches the cutoff wavelength of the second-order mode (LP(11)).

Quantum tunneling in a nonlinear matter wave interferometer

Intrinsic interparticle interactions in atomic condensates lead to an interplay between dispersion and nonlinearity of matter waves, which supports a number of nontrivial collective excitations, including dark solitons in condensates with repulsive interactions. The recent experiments have demonstrated that such nonlinear excitations play an important role in atomic interferometers [1] based on...
