6 Static potential in scalar QED 3 with non - minimal coupling
Here we compute the static potential in scalar QED 3 at leading order in 1/N f. We show that the addition of a non-minimal coupling of Pauli-type (ǫ µνα j µ ∂ ν A α), although it breaks parity, it does not change the analytic structure of the photon propagator and consequently the static potential remains logarithmic (confining) at large distances. The non-minimal coupling modifies the potentia...
متن کاملQuantum Cosmology in Scalar-tensor Theories with Non Minimal Coupling
Quantization in the minisuperspace of non minimal scalar-tensor theories leads to a partial differential equation which is non separable. Through a conformal transformation we can recast the Wheeler-DeWitt equation in an integrable form, which corresponds to the minimal coupling case, whose general solution is known. Performing the inverse conformal transformation in the solution so found, we c...
متن کامل0 Measurability of the non - minimal scalar coupling constant
The ”measurability” of the non-minimal coupling is discussed in the context of the effective field theory of gravity. Although there is no obvious motive for excluding a non-minimal scalar coupling from the theory, we conclude that for reasonable values of the coupling constant it makes only a very small correction.

متن کاملInflation by non-minimal coupling
Inflationary scenarios based on simple non-minimal coupling aφ2R and its generalizations are studied. First, generalizing the form of non-minimal coupling to K(φ)R with an arbitrary function K, we show that the flat potential still is obtainable when V (φ)/K2(φ) is asymptotically constant. Very interestingly, if the ratio of the dimensionless quartic coupling(λ) of the inflaton field and the no...
متن کاملTwo-loop Quantum Corrections of Scalar QED with Non-minimal Chern-Simons Coupling
We investigate two-loop quantum corrections to non-minimally coupled Maxwell-Chern-Simons theory. The non-minimal gauge interaction represents the magnetic moment interaction between the charged scalar and the electromagnetic field. We show that one-loop renormalizability of the theory found in previous work does not survive to two-loop level. However, with an appropriate choice of the non-mini...
