Displaced Path Integral Formulation for the Momentum Distribution of Quantum Particles
Displaced Path Integral Formulation for the Momentum Distribution of Quantum Particles
The proton momentum distribution, accessible by deep inelastic neutron scattering, is a very sensitive probe of the potential of mean force experienced by the protons in hydrogen-bonded systems. In this work we introduce a novel estimator for the end-to-end distribution of the Feynman paths, i.e., the Fourier transform of the …
