That is, because there is entanglement between spatial regions, the reduced state of such a region must necessarily be mixed (and, therefore, excited). This thus motivates the idea that at least one possible way of measuring these excitations is to iso ...

At this point, the valence band and the conduction band touch each other with a lineal dispersion relation. The physics in the low energy spectrum is described by the π orbitals of the graphene, while the high ...

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
