Entanglement of classical and quantum short-range dynamics in mean-field systems
Bru, J. B.; de Siqueira Pedra, W.
(2021-11-01)
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 ... -
Macroscopic Dynamics of the Strong-Coupling BCS-Hubbard Model,
Bru, J.-B.; de Siqueira Pedra, W. (2020)
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, ... -
Quantum Dynamics Generated by Long-Range Interactions for Lattice Fermion and Quantum Spins
Bru, J.-B.; de Siqueira Pedra, W. (2021)
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. ...
