Macroscopic quantum state analyzed particle by particle.
Macroscopic quantum phenomena, e.g., superconductivity and squeezing, are believed to result from entanglement of macroscopic numbers of particles. We report the first direct study of this kind of entanglement: we use discrete quantum tomography to reconstruct the joint quantum state of photon pairs extracted from polarization-squeezed light. Our observations confirm several predictions from sp...

متن کاملParticle Interactions Mediated by Dynamical Networks: Assessment of Macroscopic Descriptions
We provide a numerical study of the macroscopic model of Barré et al. (Multiscale Model Simul, 2017, to appear) derived from an agent-based model for a system of particles interacting through a dynamical network of links. Assuming that the network remodeling process is very fast, the macroscopic model takes the form of a single aggregation-diffusion equation for the density of particles. The th...
متن کاملParticle Consistency of Microscopic and Macroscopic Motion
The scenario of particle has been extensively written in the past, but its incompleteness is serious enough to break the connection of microscopic and macroscopic world. The th century’s cathode rays experiments by Perrin and Thomson are unable to prove whether the cathode rays are negatively charged or not. Here we propose, the subatomic and elementary particles in an atom through a capture pa...
متن کاملMacroscopic fracture characteristics of random particle systems
This paper deals with detennination of macroscopic fracture characteristics of random panicle systems. which represents a fundamental but little explored problem of micromechanics of quasibrittle materials. The panicle locations are randomly generated and the mechanical properties are characterized by a triangular softening forcedisplacement diagram for the interparticle links. An efficient alg...
