Spontaneous symmetry breaking in quantum
... Hamiltonian can in principle be diagonalized using a Bogoliubov transformation, but in doing so we find that there are some modes for which the transformation is ill-defined. These singular modes are the ones that describe the dynamics of the system as a whole 共in contrast to the dynamics of constit ...

... where β(E, g) is the renormalisation group β-function. Asymptotic freedom is signalled by g(E) → 0 as E → ∞, requiring β < 0 in this limit. In the standard model of particle physics gravity is usually ignored as it plays an inessential role in most calculations of interest. Additionally, if we view ...

Can Spacetime Curvature Induced Corrections to Lamb Shift Be
... It weakens the Lamb shift! The curvature induced Lamb shift can be remarkably significant outside a compact massive astrophysical body, e.g., the correction is ~25% at r~4M, ~16% at r~10M, ~1.6% at r~100M. The results suggest a possible way of detecting fundamental quantum effects in astronomica ...
