The paper analyzes a model of optical transmittance of ultra-diluted gas, considering gas particles’ non-locality and the quantum effect of their wave function spreading derived from solving the ...

We show that inelastic scattering in a short-range potential leads to a collapse of the wave function within standard evolution through the Schrödinger equation, whereas elastic scattering will not ...

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more ...
