We perform the matching required to compute the leading effective boundary contribution to the QED Lagrangian in the presence of a conducting surface, once the electron is integrated out. Our result resolves a confusion in the literature concerning the interpretation of the leading such correction to the Casimir energy. It also provides a useful theoretical laboratory for brane-world calculations in which kinetic terms are generated on the brane, since a lot is known about QED near boundaries. 
Effective description of brane terms in extra dimensions
We study how theories defined in (extra-dimensional) spaces with localized defects can be described perturbatively by effective field theories in which the width of the defects vanishes. These
The cosmological vacuum ambiguity, effective actions, and transplanckian effects in inflation
We provide a prescription for parametrizing the vacuum choice ambiguity in cosmological settings. We introduce an arbitrary boundary action representing the initial conditions. A Lagrangian
Introduction to Effective Field Theory
This review summarizes effective field theory techniques, which are the modern theoretical tools for exploiting the existence of hierarchies of scale in a physical problem. The general theoretical
Inflation as a probe of trans-Planckian physics: a brief review and progress report1
We provide a prescription for parametrizing the vacuum choice ambiguity in cosmological settings. We introduce an arbitrary boundary action representing the initial conditions. A Lagrangian
Technical naturalness on a codimension-2 brane
We compute how threshold effects obtained by integrating out a heavy particle localized on a codimension-2 brane influence the properties of the brane and the bulk fields it sources in D = d+2
General axisymmetric solutions and self-tuning in 6D chiral gauged supergravity
We re-examine the properties of the axially-symmetric solutions to chiral gauged 6D supergravity, recently found in refs. [12] and [13]. Ref. [12] finds the most general solutions having two
Decoupling in an expanding universe: boundary RG-flow affects initial conditions for inflation
We study decoupling in FRW spacetimes, emphasizing a Lagrangian descrip- tion throughout. To account for the vacuum choice ambiguity in cosmological settings, we introduce an arbitrary boundary
Effective electromagnetic theory for dielectric media
Light in a dielectric medium moves slower than in vacuum. The corresponding electromagnetic field equations are then no longer invariant under ordinary Lorentz transformations, but only under such

On the Casimir Effect in the High Tc Cuprates
High temperature superconductors have in common that they consist of parallel planes of copper oxide separated by layers whose composition can vary. Being ceramics, the cuprate superconductors are


Radiative corrections to the Casimir energy and effective field theory
We discuss radiative corrections to the Casimir effect from an effective field theory point of view. It is an improvement and more complete version of a previous discussion by Kong and Ravndal. By
Effective Field Theories for the Casimir Effect at Finite Temperature
We discuss corrections to the Casimir effect at finite temperature and effective field theory. Recently, it has been shown that effective field theories can reproduce radiative corrections to the
The lowest radiative correction to the Casimir energy density between two parallel plates is calculated using effective field theory. Since the correlators of the electromagnetic field diverge near
Quantum field theory and unification in AdS5
We consider gauge bosons in the bulk of AdS5 in a two-brane theory that addresses the hierarchy problem. We demonstrate that one can do a perturbative calculation above the IR scale associated with
High energy field theory in truncated anti-de Sitter space.
In this Letter we show that in five-dimensional anti-de Sitter (AdS) space truncated by boundary branes, effective field theory techniques are reliable at high energy (much higher than the scale
Effective field theory and matching in nonrelativistic gauge theories
The effective Lagrangian and power counting rules for nonrelativistic gauge theories are derived via a systematic expansion in the large c limit. It is shown that the 1/c expansion leads to an
Effective field theory and unification in AdS backgrounds
This work is an extension of our previous work, hep-th/0204160, which showed how to systematically calculate the high energy evolution of gauge couplings in compact AdS_5 backgrounds. We first
