XM Puspus & FNC Paraan. Rényi entanglement entropy of the spin-partitioned BCS ground state, in Proceedings of the 33rd Samahang Pisika ng Pilipinas Physics Congress, spp-2015-2B-03 (University of Northern Philippines, Vigan City, 2015).
Abstract
<div>We use the Rényi entanglement entropy to study entanglement between the spin components of the Bardeen-Cooper-Schrieffer (BCS) ground state and we characterize its limiting values. We show that Rényi entropies peak in the region about the Fermi surface. We also show that the orbital single-copy entanglement can be interpreted as the thermodynamic free energy of a two-level system at thermal equilibrium.
