the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Finite temperature amplitudes and reaction rates in Thermofield dynamics
We propose a method for calculating the reaction rates and transition amplitudes of generic process taking place in a many body system in equilibrium. The relationship of the scattering and decay amplitudes as calculated in Thermo Field Dynamics the conventional techniques is established. It is shown that in many cases the calculations are relatively easy in TFD. PACS number(s):11.10.Wx,11.15Bt...
متن کاملQuantum phase space distributions in thermofield dynamics
It is shown that the the quantum phase space distributions corresponding to a density operator ρ can be expressed, in thermofield dynamics, as overlaps between the state | ρ > and ”thermal” coherent states. The usefulness of this approach is brought out in the context of a master equation describing a nonlinear oscillator for which exact expressions for the quantum phase distributions for an ar...
متن کاملWell-dressed states for wave-packet dynamics in cavity QED
The quantization of atomic center-of-mass motion is considered within the context of cavity QED with particular emphasis on the dynamics of localized wave packets. ‘‘Well-dressed’’ states are introduced as an eigenbasis that incorporates both the quantized atom-field interaction and the external bound states of a potential well. The interplay of internal and external time scales generates quali...
متن کاملFull Observation of Single-atom Dynamics in Cavity Qed
We report the use of broadband heterodyne spectroscopy to perform continuous measurement of the interaction energy Eint between one atom and a highnesse optical cavity, during individual transit events of 250 s duration. We achieve a fractional sensitivity 4 10 = p Hz to variations in Eint=~ within a measurement bandwidth that covers 2.5 decades of frequency (1{300 kHz). Our basic procedure is ...
