Spin filtering and entanglement detection due to spin-orbit interaction
... polarization for an outgoing current is obtained if only one SOI-split subband contributes to the outgoing transport. This polarization can be reversed to opposite, yet not perfect polarization upon small changes of the gate potential such that further subbands become active for the transport. At fi ...

Two-Fluid Model for Heavy Electron Physics
... Heavy electron materials exhibit a number of anomalous properties in the normal states that demand a unified explanation. The two-fluid model relates most of these anomalies to the emergence of the heavy electron Kondo liquid and the corresponding loss of strength of the local moments below T ∗ . In ...

Characterizing and witnessing multipartite correlations: from nonlocality to contextuality PhD thesis
... lead to the formal definition of Nonlocality by J. Bell in 1964 (Bel64). This phenomenon of nonlocality tells that correlations observed among the outcomes of spacelike separated measurements on a quantum system may be stronger than those predicted by classical mechanics. Since then, and up to looph ...
