An interpretation of the field-emission images of molecules, impurity ions, and nanostructures placed on the tip of a field-emission microscope is given. It is shown that often such images represent nothing else but the visualization of the wave function of the emitted quantum particle in the m...
In particular, apart from the probability (density) field in the OCS, the wave function also suggests the existence of two fields that predict two (equiprobable) particle momentum values for each OCS point, and the average of these two momenta at each point is related only to the wave ...

charged scalar particles mediated by a-scalar particle, focusing on the momentum non-conserving contribution of the scattering amplitude. We define a generalization of the usual cross section in order to quantify the emergence of these events. We also study the allowed kinematical region for momentum...
function using some stochastic analysis and find the equation governing it. We show that, in addition to the screening length found by others, there is a characteristic length scale for the screening, namelyqchwhich is related to the disorder strength and inter-particle interactions viaqch≡π42...
WMs (and WVs) have proved to be a powerful tool for addressing fundamental questions in quantum mechanics, such as the direct measurement of the wave function of a particle21–23, as well as for technical applications, such as enhanced precision measurements24,25 or the active control of ...
A free electron has wave function Ψ(x, t) = sin(kx − ωt) Determine the electron’s de Broglie wavelength, momentum, kinetic energy and speed when k = 50nm-1 Also, I know that the equations relating the speed v, momentum p, de Broglie wavelength λ...
formalism [3, 21, 22], the two-particle correlation function is obtained by convoluting the emission function g(p, x), i.e., the probability for emitting a particle with momentum p from the space-time point x = (r, t), with the relative wave function of the two particles, ...
Orbital angular momentum (OAM) multiplexing technique has recently emerged and generated widespread interests since the OAM was discovered as a property of electromagnetic wave and acoustic wave. It was widely acknowledged that OAM multiplexing can achieve very high effective degrees of freedom (EDOF) ...
Intuitively, the simplest geometry of the scatterers for projecting the evanescent-field transverse-spin information into far-field with high fidelity is a spherical Rayleigh particle22. However, the fabrication of sub-micron spherical scatterers, whether of metallic or dielectric nature, placed uniformly...
