    "abstract": "The von Neumann entropy of various quantum dissipative models is calculated\nin order to discuss the entanglement properties of these systems. First,\nintegrable quantum dissipative models are discussed, i.e., the quantum Brownian\nmotion and the quantum harmonic oscillator. In case of the free particle, the\nrelated entanglement of formation shows no non-analyticity. In case of the\ndissipative harmonic oscillator, there is a non-analyticity at the transition\nof underdamped to overdamped oscillations. We argue that this might be a\ngeneral property of dissipative systems. We show that similar features arise in\nthe dissipative two level system and study different regimes using sub-Ohmic,\nOhmic and and super-Ohmic baths, within a scaling approach.",
