Entanglement at Finite Temperature in the Electronic Two-Particle Interferometer

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

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 experiment displayed a clear two-particle Aharonov-Bohm effect, however with an amplitude suppressed due to finite temperature and dephasing. In our recent work Samuelsson, Neder, and Buttiker, Phys. Rev. Lett. 102, 106804 (2009) we presented a general theory for finite temperature entanglement in mesoscopic conductors and applied it to the 2PI, here further discussed.
