Entanglement bounds for single-excitation energy eigenstates of quantum oscillator systems

We provide an analytic method for estimating the entanglement of the non-Gaussian energy eigenstates of disordered harmonic oscillator systems. We invoke the explicit formulas of the eigenstates of the oscillator systems to establish bounds for their ϵ -Rényi entanglement entropy ϵ ∈ ( 0 , 1 ) . Our...
