"A steady state   thermodynamic entanglement witness"


 

Abstract



We present a method for entanglement detection in steady state systems using a thermodynamic witness.  To illustrate, we consider an example and find that for an XX spin chain, the presence of an energy current increases the region of entanglement detected by the steady state witness.  Further, we find that entanglement exists even at a high steady state temperature.  We also discuss concurrence in the steady state system and find that the amount of entanglement can be increased by the current.
