Wave packets in quantum theory of collisions
Two methodological troubles of the quantum theory of collisions are considered. The first is the undesirable interference of the incident and scattered waves in the stationary approach to scattering. The second concerns the nonstationary approach to the theory of collisions of the type a + b → c + d. In order to calculate the cross section one uses the matrix element 〈cd|S|ab〉 of the S-matrix. ...
متن کاملQuantum Measurement Theory in Gravitational-Wave Detectors
The fast progress in improving the sensitivity of the gravitational-wave detectors, we all have witnessed in the recent years, has propelled the scientific community to the point at which quantum behavior of such immense measurement devices as kilometer-long interferometers starts to matter. The time when their sensitivity will be mainly limited by the quantum noise of light is around the corne...
متن کاملPilot Wave Theory and Quantum Fields
Assignment: One approach to solving the measurement problem in quantum theory proposes that a certain quantity Q is `preferred' in that a quantum system always has a de nite value for it. So Q needs to be chosen so that: 1. its de nite values appropriately explain the de niteness of the macrorealm, and this will presumably involve equations of motion for the values that mesh suitably with the q...
متن کاملPulse - Echo Shear Wave Transducer
Type and size are the most important defect characteristics that need to oe determined for reliable prediction of the remaining service lifetime of a defective structure or part. The analytical and supporting experimental results presented in this paper concern a universal ultrasonic defect-identificationand-subsequent-sizing method. The conceived satellite-pulse technique (SPT) is based on the...
متن کاملOptimized Perturbation Theory for Wave Functions of Quantum Systems
The notion of the optimized perturbation, which has been successfully applied to energy eigenvalues, is generalized to treat wave functions of quantum systems. The key ingredient is to construct an envelope of a set of perturbative wave functions. This leads to a condition similar to that obtained from the principle of minimal sensitivity. Applications of the method to quantum anharmonic oscill...
