Ramsey’s method of separated oscillating fields and its application to gravitationally induced quantum phase shifts
نویسندگان
چکیده
We propose to apply Ramsey’s method of separated oscillating fields to the spectroscopy of the quantum states in the gravity potential above a horizontal mirror. This method allows a precise measurement of quantum mechanical phaseshifts of a Schrödinger wave packet bouncing off a hard surface in the gravitational field of the Earth. Measurements with ultracold neutrons will offer a sensitivity to Newton’s law or hypothetical short-ranged interactions, which is about 21 orders of magnitude below the energy scale of electromagnetism.

Neutron-multiwave-interference experiments with many resonance coils
Neutron-multiwave-interference phenomena based on Ramsey’s resonance method of ‘‘separated oscillating fields’’ are studied. A neutron passes through N successive resonant coils (\v052mnB0), which flip the neutron spin with a probability r smaller than 1. These coils are separated by path lengths L over which a homogeneous field B1 is present. Because the spin-flip probability r is smaller than...

A new two-step implicit linear Obrechkoff twelfth algebraic order method with vanished phase-lag and its first, second, third and fourth derivatives is constructed in this paper. The purpose of this paper is to develop an efficient algorithm for the approximate solution of the one-dimensional radial Schrodinger equation and related problems. This algorithm belongs in the category of the multist...
متن کاملEntanglement of an Atom and Its Spontaneous Emission Fields via Spontaneously Generated Coherence
The entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. The effect of spontaneously generated coherence (SGC) on entanglement between the atom and its spontaneous emission fields is then discussed. We find that in the presence of SGC the entanglement between the atom and its spontaneous emission fields is completely phase dependent, while in absen...

In this paper, we report on the design and fabrication of a low-cost phase shifter for application in phase shifting interferometry. Phase shifting interferometry is a powerful method for surface characterization. It uses interference data recorded during a series of predetermined phase shifts to recover the induced phase by the object surface. These controlled phase shifts are typically perfor...
متن کاملCoherent Control of Quantum Entropy via Quantum Interference in a Four-Level Atomic System
The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...
