This book is on the study of the non-resonant interaction between a three-level type atom and a single mode cavity field. An effective model, where one of the three levels has been eliminated is introduced when the center-of-mass and the classical homogenous gravitational field are taken into account. Also, the homotopy analysis method is used on solving the explicit three-level model. Moreover, the idea of using the explicit time-dependence on the atom-field couplings, but for an extended model is presented. The nonlinearity effects and the intensity-dependent coupling are also explored. Numerical investigations are used to test the collapses-revivals, the anti-bunching of photons, the disentanglement of the atom from the field and the squeezing phenomena.
The study investigated the effects of noise on quantum coherence and quantum entanglement in quantum information through the interaction between an atomic system described by a two or three-level particle and quantized radiation field, which can have one or two modes and that system is coupled to reservoir. The entanglement in the interacting system of a single mode thermal field and a single qubit with dissipation in the dispersive limit was investigated. The effects of thermal photons on entanglement and coherence loss were investigated. It has been found that, the field is inhibited from going into a pure state and coherence is lost faster than in the case of zero temperature. The temporal evolution of entanglement for a single-mode field interacting with a two-level atom via intensity-dependent coupling in the off-resonant case has been studied, where the leakage of photon through the cavity has been taken into account. Based on the master equation for the density matrix, the dynamics of the entanglement of the three-level atom interacting with single-mode field in a finite-Q cavity were studied.
High Quality Content by WIKIPEDIA articles! Photosensors or photodetectors are sensors of light or other electromagnetic energy. There are several varieties:Optical detectors, which are mostly quantum devices in which an individual photon produces a discrete effect.Chemical detectors, such as photographic plates, in which a silver halide molecule is split into an atom of metallic silver and a halogen atom. The photographic developer causes adjacent molecules to split similarly.Photoresistors or Light Dependent Resistors (LDR) which change resistance according to light intensity.Photovoltaic cells or solar cells which produce a voltage and supply an electric current when illuminated.Photodiodes which can operate in photovoltaic mode or photoconductive mode.Photomultiplier tubes containing a photocathode which emits electrons when illuminated, the electrons are then amplified by a chain of dynodes.Phototubes containing a photocathode which emits electrons when illuminated, such that the tube conducts a current proportional to the light intensity.Phototransistors, which act like amplifying photodiodes.
In this book, we study the system that consists of a two 2-level atoms interacting with a single-mode or two-mode quantized radiation field in the absent or presence of the Stark shift. Both atoms are prepared initially in the exited state and the field in a coherent state. An analytical solution for the system of two identical 2-level atom is obtained. The phase distribution, phase variance and Wigner function are investigated. The influence of the Stark shift on the Wigner function and the phase properties is analyzed. We investigate the purity loss of the system and bipartite partitions of the system. The effects of the Stark shift on the purity loss of the system and different bipartite partitions of the system (field-two atoms, atom-(field+atom)) through the tangles are considered. In particular, the effect of the Stark shift on the amount of entanglement between atoms and field is evaluated by the negativity. Entanglement dynamics between the two atoms taking into account the effect of the emission is studied by using various measures of entanglement.
This thesis presents a detailed and successful study of molecular self-assembly on the calcite CaCO3(1014) surface. One reason for the superior applicability of this particular surface is given by reflecting the well-known growth modes. Layer-by-layer growth, which is a necessity for the formation of templated 2D molecular structures, is particularly favoured on substrates with a high surface energy. The CaCO3(1014) surface is among those substrates and, thus, most promising.All experiments in this thesis were performed using the NC-AFM technique under ultrahigh vacuum conditions. The acquisition of drift-free data became in this thesis possible owing to the herein newly developed atom-tracking system. This system features a lateral tippositioning precision of at least 50 pm. Furthermore, a newly developed scan protocol was implemented in this system, which allows for the acquisition of dense 3D data under roomtemperature conditions. An entire 3D data set from a CaCO3(1014) surface consisting of 85 × 85 × 500 pixel is discussed.The row-pairing and (2 × 1) reconstructions of the CaCO3(1014) surface constitute most interesting research subjects. For both reconstructions, the NC-AFM imaging was classified to a total of 12 contrast modes. Eight of these modes were observed within this thesis, some of them for the first time. Together with literature findings, a total of 10 modes has been observed experimentally to this day. Some contrast modes presented themselves as highly distancedependent and at least for one contrast mode, a severe tip-termination influence was found. Most interestingly, the row-pairing reconstruction was found to break a symmetry element of the CaCO3(1014) surface. With the presence of this reconstruction, the calcite (1014) surface becomes chiral. From high-resolution NC-AFM data, the identification of the enantiomers is here possible and is presented for one enantiomer in this thesis.Five studies of self-assembled molecular structures on calcite CaCO3(1014) surfaces are presented. Only for one system, namely HBC/CaCO3(1014), the formation of a bulk structure was observed. This well-known occurence of weak molecule-insulator interaction hinders the investigation of two-dimensional molecular self-assembly. It was, however, possible to force the formation of an island phase for this system upon following a variable-temperature preparation. For the C60/CaCO3(1014) system it is most notably that no branched island morphologies were found. Instead, the first C60 layer appeared to wet the calcite surface.
The aim of this book is to present the fundamental concepts and properties of quantum mechanics, in particular the field of quantum optics. In this book we have studied some extensions and generalizationsof the Jaynes-Cummings model JCM for the radiation-matter interactions. We have reviewedthe JCM and its various modifications and some important quantum characteristics.The interaction of two two-level atoms with a single mode cavity field is studied. The interaction of a four-level rubidium atom and one mode field in a cavity in the presence of intensity dependent coupling between the field and the atom is presented. The interaction of a moving four-level rubidium atom with two-mode cavity field in an additional Kerr medium has been studied. Some non classical statistical properties of a model for the interaction between a four-level atom with a three-mode field in a cavity containing a Kerr-like medium are investigate.
