Finite Quantum Fluctuations About Static Field Configurations

چکیده
We develop an unambiguous and practical method to calculate one-loop quantum corrections to the energies of classical time-independent field configurations in renormalizable field theories. We show that the standard pertur-bative renormalization procedure suffices here as well. We apply our method to a simplified model where a charged scalar couples to a neutral " Higgs " field, and compare our results to the derivative expansion.

Quantum effects on winding configurations in SU(2)-Higgs theory
We examine the quantum corrections to the static energy for Higgs winding configurations in order to ascertain whether such corrections may stabilize solitons in the standard model. We evaluate the effective action for winding configurations in Weinberg-Salam theory without U(1)gauge fields or fermions. For a configuration whose size, a ≪ m−1 where m = max{mW ,mH}, mW is the W-mass, and mH is t...
متن کاملQuantum effects of compactified AdS 5 geometry on the higgs potential
In this paper we determine the one loop radiative correction to the higgs potential due to quantum fluctuations about the background metric of Randall-Sundrum model. We then examine the effects of the one loop effective potential on the stability of the classical vacuum paying particular attention to the tadpole terms which could dominate over the classical potential for small field configurati...
متن کاملStructure and Dynamics of Monopoles in Axial-Gauge QCD
An investigation of singular fields emerging in the process of transforming QCD to the axial gauge is presented. The structure of the singularities is analyzed. It is shown that apart from well known neutral magnetic monopole singularities, the field configurations also exhibit singularities in their charged and transverse components. This complex singularity structure guarantees finite non-Abe...
متن کاملLarge “Dipolar” Vacuum Fluctuations in Quantum Gravity
We study a novel set of gravitational field configurations, called “dipolar zero modes”, which give an exactly null contribution to the Einstein action and are thus candidates to become large fluctuations in the quantized theory. They are generated by static unphysical sources satisfying (up to terms of order G) the simple condition ∫ dxT00(x) = 0. We give two explicit examples of virtual sourc...
متن کاملFaraday rotation echo spectroscopy and detection of quantum fluctuations
Central spin decoherence is useful for detecting many-body physics in environments and moreover, the spin echo control can remove the effects of static thermal fluctuations so that the quantum fluctuations are revealed. The central spin decoherence approach, however, is feasible only in some special configurations and often requires uniform coupling between the central spin and individual spins...
