Atom interferometry in the presence of an external test mass

The influence of an external test mass on the phase of the signal of an atom interferometer is studied theoretically. Using traditional techniques in atom optics based on the density matrix equations in the Wigner representation, we are able to extract the various contributions to the phase of the signal associated with the classical motion of the atoms, the quantum correction to this motion resulting from atomic recoil that is produced when the atoms interact with Raman field pulses, and quantum corrections to the atomic motion that occur in the time between the Raman field pulses. By increasing the effective wave vector associated with the Raman field pulses using modified field parameters, we can increase the sensitivity of the signal to the point where the quantum corrections can be measured. The expressions that are derived can be evaluated numerically to isolate the contribution to the signal from an external test mass. The regions of validity of the exact and approximate expressions are determined.Comment: 23 pages, 3 figures, 2 table

The Nature of Beauty and Its Objective Manifestation Serve as Evidence of the God Described in the Bible

In exploring the concept of objective beauty in nature, a strong argument emerges for the existence of a divine creator as described in the Bible. This thesis, titled “The Nature of Beauty and its Objective Manifestation Serve as Evidence of the God Described in the Bible,” proposes that the intricate design and objective manifestation of beauty in the world are indicative of a higher transcendent being, prompting us to contemplate the profound mysteries of creation and the interconnectedness of aesthetics and spirituality. Through this lens of beauty, we are challenged to engage in a thought-provoking discourse that encompasses apologetics, philosophy, theology, and aesthetics, ultimately leading us to recognize and contemplate the presence of a higher power within the wondrous tapestry of the cosmos, as illustrated in Psalm 19:1-4 and Romans 1:18-20. From this perspective, we can confidently assert that the nature of beauty and its objective manifestation support the rational and reasonable belief in the Biblical God. This should incite us to delve deeper into examining beauty as a revelatory sign pointing towards a transcendent reality beyond our immediate sensory experiences, urging us to reflect on the intricate interplay between aesthetics, divinity, and the mysterious aspects of creation. Thus, beauty found in nature serves as a continual invitation to acknowledge and contemplate the presence of the Biblical God, encouraging us to seek out the profound truths hidden beneath the surface of our everyday perceptions

Landau equations and asymptotic operation

The pinched/non-pinched classification of intersections of causal singularities of propagators in Minkowski space is reconsidered in the context of the theory of asymptotic operation as a first step towards extension of the latter to non-Euclidean asymptotic regimes. A highly visual distribution-theoretic technique of singular wave fronts is tailored to the needs of the theory of Feynman diagrams. Besides a simple derivation of the usual Landau equations in the case of the conventional singularities, the technique naturally extends to other types of singularities e.g. due to linear denominators in non-covariant gauges etc. As another application, the results of Euclidean asymptotic operation are extended to a class of quasi-Euclidean asymptotic regimes in Minkowski space.Comment: 15p PS (GSview), IJMP-A (accepted
