Entanglement of classical and quantum short-range dynamics in mean-field systems
The relationship between classical and quantum mechanics is usually understood via the limit ħ→0. This is the underlying idea behind the quantization of classical objects. The apparent incompatibility of general relativity ...
Quantum Dynamics Generated by Long-Range Interactions for Lattice Fermion and Quantum Spins
We study the macroscopic dynamics of fermion and quantum-spin systems with long-range, or mean-field, interactions, which turns out to be equivalent to an intricate combination of classical and short-range quantum dynamics. ...
Macroscopic Dynamics of the Strong-Coupling BCS-Hubbard Model,
The aim of the current paper is to illustrate, in a simple example, our recent, very general, rigorous results on the dynamical properties of fermions and quantum-spin systems with long-range, or meanfield, interactions, ...
