"Entanglement entropy from thermodynamic entropy"

Mohammad Magrebi , JQI Maryland/NIST
[Host: Israel Klich]

In recent years, entanglement has become a main frontier with applications across several fields in physics. Nevertheless, simple conceptual pictures and practical ways to compute the entanglement, especially in many-body systems, have remained elusive. In this talk, I will consider a simple setup where a dispersive medium becomes entangled with zero-point fluctuations in the vacuum. I show that the entanglement entropy of the material body with the vacuum can be viewed as the classical thermodynamic entropy in one higher dimension. Such mapping allows us to immediately verify the quantum version of the strong subadditivity property. As a byproduct of our formalism, I show that the entanglement finds a simple pictorial interpretation in terms of phantom polymers.
