Semiclassical entanglement entropy for spin-field interaction
Matheus V. Scherer, Lea F. Santos, Alexandre D. Ribeiro
We study a general bipartite quantum system consisting of a spin interacting with a bosonic field, with the initial state prepared as the product of a spin coherent state and a can…

Testing trajectory-based determinism via time probability distributions
Matheus V. Scherer, Alexandre D. Ribeiro, Renato M. Angelo
It is notorious that quantum mechanics cannot predict well-defined values for all physical quantities. Less well-known, however, is the fact that quantum mechanics is unable to fur…

Entanglement dynamics of spins using a few complex trajectories
Matheus V. Scherer, Alexandre D. Ribeiro
In this work, we consider two spins initially prepared in a product of coherent states and study their entanglement dynamics due to a general interacting Hamiltonian. We adopt an a…
