	abstract = {The R{\'e}nyi entanglement entropy is calculated exactly for mode-partitioned isolated systems such as the two-mode squeezed state and the multi-mode Silbey{\textendash}Harris polaron ansatz state. Effective thermodynamic descriptions of the correlated partitions are constructed to present quantum information theory concepts in the language of thermodynamics. Boltzmann weights are obtained from the entanglement spectrum by deriving the exact relationship between an effective temperature and the physical entanglement parameters. The partition function of the resulting effective thermal theory can be obtained directly from the single-copy entanglement.},

	abstract = {<div>We study mode entanglement in four quantum states (coherent state, squeezed vacuum state, displaced squeezed state, squeezed coherent state), which are generated from a bosonic two-mode vacuum state by the action of displacement and squeezing operators. The mode entanglement entropy in these states is calculated and shown to depend only on the squeezing magnitude.</div>},

	abstract = {<div>Mode entanglement in a two-mode squeezed state is studied. The entanglement spectrum is derived and interpreted as Boltzmann coefficients of harmonic oscillator eigenstates at thermal equilibrium. The effective temperature is expressed in terms of squeezing parameters and is equal to zero when the state is unsqueezed and increases without bound as the state is infinitely squeezed. It is demonstrated that the reduced density operator can be identified as a canonical ensemble of single harmonic oscillator at some effective temperature Te. The R{\'e}nyi entanglement entropy is calculated and found to increase without bound as the squeezing parameter increases. The single-copy entanglement, which is a limiting value of the R{\'e}nyi entropy, is interpreted as a partition function.</div>},
