Coherence of k-space electrons: application to TDS electrons by DBI.
Methods of controlled electron interference in k-space on the diffraction plane by means of an electron biprism invented during the Tonomura Electron Wavefront Project are briefly reviewed. The results presented show the partial coherence of self-interfered diffusely scattered electrons, elastically scattered and inelastically scattered, found outside and in between the Bragg diffracted beams o...
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...

متن کاملCoherent matter wave inertial sensors for precision measurements in space
We analyze the advantages of using ultra-cold coherent sources of atoms for matter-wave interferometry in space. We present a proof-of-principle experiment that is based on an analysis of the results previously published in [1] from which we extract the ratio h/m for 87 Rb. This measurement shows that a limitation in accuracy arises due to atomic interactions within the Bose-Einstein condensate...
متن کاملOptimisation of sample thickness for THz-TDS measurements
How thick should the sample be for a transmission THz-TDS measurement? Should the sample be as thick as possible? The answer is ‘no’. Although more thickness allows T-rays to interact more with bulk material, SNR rolls off with thickness due to signal attenuation. Then, should the sample be extremely thin? Again, the answer is ‘no’. A sample that is too thin renders itself nearly invisible to T...
