A Route toward Quantum Gravity through the Imaginary-Time Field Theory
A possible way toward the quantization of a weak gravitational field inspired
by the imaginary-time field theory is discussed. The analogies of the general
relativity in the canonical formulation with the thermodynamic geometry and
superfluids are also pointed out. The proposed regularization method in the
imaginary-time formalism of field theory shows a good chance removing
theoretical obstacles and constructing a perturbative theory of quantum
gravity.Comment: 13 pages, 3 figures, some corrections have been mad
An Electroweak-like Theory from Four Fermion Interactions
An electroweak-like theory of a broken chiral symmetry that is constructed by
the collective modes of fermion pairs from four fermion interactions of one
lepton generation is presented. The products of Dirac spinors lead to the
separation of the two chiral fermions to couple respectively with two different
kinds of polarization states. Because of a broken vacuum, a fermion and an
anti-fermion out of the four pair up to form vector bosons, which behave like
gauge bosons, such as , and in a group structure of
. The pairing of spinors only allows left-handed fermions
to interact with charged bosons to secure the gauge invariance, while, as
desired, -like bosons mediate different weak forces for two chiral fermions
and -like bosons interact freely with fermions.Comment: 15 page
