NettetFirst, classical physics works on bodies, and quantum mechanics (the math method under quantum theory) works statistically. However, if you have a frame-of-reference, … Nettet8. mai 2015 · We consider the ℏ→0 limit of the quantum dynamics generated by the HamiltonianH(ℏ)=−(ℏ2/2m)Δ+V. We prove that the evolution of certain Gaussian states is determined asymptotically as ℏ→0 by classical mechanics. For suitable potentialsV inn≧3 dimensions, our estimates are uniform in time and our results hold for scattering …
Nettet10. apr. 2024 · In this paper, we consider a deformable continuous medium and its discrete representation realized by a lattice of points. The former is solved using the classical variational formulation with the finite element method. The latter, a 2D discrete “kinematic” model, instead is conceived to determine the displacements of the lattice points … Nettet5. aug. 2014 · The failure of Classical Physics was highlighted by black body radiation and photoelectric effect. Max Planck and Albert Einstein provided explanations of both phenomena based on quantum...
