Entanglement at Finite Temperature in the Electronic Two-Particle Interferometer
In this work we discuss a theory for entanglement generation, characterization and detection in fermionic two-particle interferometers (2PI) at finite temperature. The motivation for our work is provided by the recent experiment by the Heiblum group, Neder et al. Nature 448, 333 (2007), realizing the 2PI proposed by Samuelsson, Sukhorukov, and Buttiker, Phys. Rev. Lett. 92, 026805 (2004). The expe
