... explosive growth of vacuum polarization of quantum fields), that may always prevent spacetime from developing closed timelike curves (i.e ... the structure of spacetime only if they are threaded by quantum fields in quantum states that violate the averaged null energy condition (i.e ... This has triggered research to explore the ability of quantum fields to possess such extended negative energy ...
... The predictions of for n > 1 change when the classical fields (complex numbers or c-numbers) are replaced with quantum fields (operators or q-numbers) ... In general, quantum fields do not necessarily commute, with the consequence that their order in the above expressions can not be simply interchanged ...
... In classical field theory, the field is part of the state of the system, so in order to describe it completely one effectively introduces separate variables for every ... In quantum mechanics, the classical variables are turned into operators, but these do not capture the state of the system, which is instead encoded into a wavefunction or more abstract ket vector ... Quantum fields relate to quantum mechanics as classical fields do to classical mechanics, i.e ...
Famous quotes containing the words fields and/or quantum:
“Smart lad, to slip betimes away
From fields where glory does not stay,
And early though the laurel grows
It withers quicker than the rose.”
—A.E. (Alfred Edward)
“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (18961948)
