Experimentally friendly geometrical criteria for entanglement

, : Experimentally friendly geometrical criteria for entanglement. Physical Review Letters 100(14): 140403-140403

A simple geometrical criterion gives experimentally friendly sufficient conditions for entanglement. Its generalization gives a necessary and sufficient condition. It is linked with a family of entanglement identifiers, which is strictly richer than the family of entanglement witnesses.

(Coleoptera, Scolytidae) in the Swietokrzyski National Park. Cryphalus piceae shows increased numbers in weakened fir (Abies alba) stands in the Swietokrzyski National Park, Poland, and accelerates the stand dieback process. This study investigated the density of colonization of trap trees laid out at locat...

We studied the ecology of Cnemidophorus lacertoides at a restinga habitat in southern Brazil. Peak activity occurred between 12.00 and 15.00. The mean body temperature of active lizards (35.0 plus or minus 2.9 deg. C) was relatively low compared w...
