Exponential concentration of fluctuations in mean-field boson dynamics
Matias Gabriel Ginzburg, Simone Rademacher, Giacomo De Palma
We study the mean-field dynamics of a system of interacting bosons starting from an initially condensated state. For a broad class of mean-field Hamiltonians, including models…

Failure of the mean-field Hartree approximation for a bosonic many-body system with non-Hermitian Hamiltonian
Matias Ginzburg, Simone Rademacher, Giacomo De Palma
Mean-field Hartree theory is a central tool for reducing interacting many-body dynamics to an effective nonlinear one-particle evolution. This approximation has been employed also…
