Decoherence due to photon scattering in an atom interferometer was studied as a function of laser frequency near an atomic resonance. The resulting decoherence (contrast-loss) spectra will be used to calibrate measurements of tune-out wavelengths that are made with the same apparatus. To support this goal, a theoretical model of decoherence spectroscopy is presented here along with experimental tests of this model.

This Dissertation describes how I used a three nanograting Mach-Zehnder atom beam interferometer to precisely measure a wavelength of light, known as a tune-out wavelength, that causes zero energy shift for an atom. I also describe how such measurements can be remarkably sensitive to rotation rates. It is well known that atom interferometry can be used to measure accelerations and rotations, but it was a surprise to find out that tune-out wavelength measurements can under certain conditions be used to report the absolute rotation rate of the laboratory with respect to an inertial frame of reference. I also describe how we created conditions which improve the accuracy of tune out wavelength measurements. These measurements are important because they serve as a benchmark test for atomic structure calculations of line strengths, oscillator strengths, and dipole matrix elements. I present a new measurement of the longest tune-out wavelength in potassium, λzero = 768.9701(4) nm. To reach sub-picometer precision, an optical cavity surrounding the atom beam paths of the interferometer was used. Although this improved the precision of our experiment by increasing the light-induced phase shifts, the cavity also brought several systematic errors to our attentions. For example, I found that large ±200 pm shifts in tune-out wavelengths can occur due to the Earth's rotation rate. To solve this problem, I demonstrated that controlling the optical polarization, the magnetic field, and the atom beam velocity distribution can either suppress or enhance these systematic shifts. Suppressing these systemic shifts in tune-out wavelengths is useful for precision measurements used to test atomic structure calculations. By enhancing these systematic shifts, the interferometer can be a gyroscope that utilizes tune-out wavelengths.

Esta dissertação intenciona investigar a construção do cômico, mediado pela tecnologia, em vídeos remix publicados na plataforma YouTube. Os trabalhos analisados propõem o riso a partir da manipulação de tempo e pitch do áudio de vídeos virais, possibilitada por softwares como Auto-Tune e Melodyne. Entendemos remix conforme autores como Lev Manovich, Eduardo Navas e Lawrence Lessig, que afirmam que vivemos em uma \"Cultura Remix\", uma época que tem como base cultural o sampling, atividade que consiste na troca inteligente entre fragmentos de diversas mídias. Analisaremos a emergência do riso nesse contexto, a partir de reapropriações de materiais preexistentes na rede. Autores como Henri Bergson e Michail Bakhtin nos fornecem o suporte conceitual para investigarmos o riso como um recurso dramático e da cultura tanto na vida cotidiana quanto nas plataformas digitais, que facilitaram, por um lado, o acesso e reciclagem de \"detritos midiáticos\", e, por outro, potencializaram as possibilidades de manipulação desses materiais / This dissertation intends to investigate the construction of the comic, mediated by technology, in video remix published on the YouTube platform. The analyzed works propose the laughter from the manipulation of time and pitch of the audio of viral videos, made possible by softwares like Auto-Tune and Melodyne. We understand remix by authors such as Lev Manovich, Eduardo Navas and Lawrence Lessig, who claim that we live in a \"Culture Remix\", an era that is based on cultural sampling, an activity that consists of the intelligent exchange between fragments of various media. We will analyze the emergence of laughter in this context, from re-appropriation of pre-existing materials in the network. Authors such as Henri Bergson and Michail Bakhtin provide us with conceptual support for investigating laughter as a dramatic and cultural resource in everyday life as well as on digital platforms that facilitated access to and recycling of \"media debris\" on the one hand, and , on the other, potentialized the possibilities of manipulation of these materials.

The poetry of Tang, and the chis of Song are both the greatest literary styles in Chinese literature. Chis was widespread in Tang Dynasty, Five Dynasty and Ten-Kindom preiod, and Song Dynasty. During these periods, the names of chis had been changed and the amount had enlarged as well. Some of chis were used quite often and became the top ten songs. However; some of them only used few times, then disappeared. From those chis, the rise and fall of the dynasties, the news of societies and their cultural orientation were revealed. The relationship of the tune and the content of chis was the source of the authors¡¦ inspiration. Therefore, the relationship of the tune and the content of chis is important. To be the researcher of chis, it is necessary to realize the origin of chis and make a thorough understanding of them. So as to the study of chis. In the dissertation, the researcher started from quantitative and qualitative methods, as well as counted the number of tunes, sorted by ¡§the rules of chis¡¨ of¸U¾ð (Qing Dynasty) and 838 tunes of chis. It was concluded that the authors of chis in Tang Dynasty, Five-Dynasty and Ten-Kindom period and Song Dynasty often used traditional culture and folk tales as metaphor and construct the principles of chis. This dessertation was divided into six parts. Except of introduction and conclusion, there are four chapters which contain one dynasty respectively. Tang Dynasty, Five-Dynasty and Ten-Kindom preiod, and Song Dynasty, were three important periods when chis emerged, expand and mature. The development of chis was discussed in chapter two, three, and four, respectively. By studying initial chis of the authors in these three periods, the relationship of the tune and the content of chis was concluded in chapter five, which is the major point of this dessertation. Hopefully, the relationship among the different authors, various places, and dynasties could be revealed. Therefore, to study ¡§ how did the people at that time handle the tune of chis?¡¨ is very important. The authors of the tonal pattern and rhyme scheme was the tune of chis, which was formed in the court music of Sui Dynasty. In Five-Dynasty and Ten-Kindom preiod, court music, foreign music and folk music combined into chis. This new literature style described the happiness or sadness of the people at that time and sutisfied their emotional needs. The conclusions of this dessertation 1.The relationship of the tune and the content of chis is determined. 2.The tune of chis is related to its content when it initialed. However, the tune and its content were enlarged and changed in Song Dynasty. 3.The sentences in chis were similar to those in poetry. The intertextuality might deserve to be discussed in further study.
