A Repulsive Casimir Effect for Circular Geometries
Daniel Davies
Using numerical analytic continuation, we compute the Zeta function for the Casimir Effect for circular geometries in 2+1 dimensions. After subtraction of the simple pole of the ze…
Negative Infrared Divergent Corrections to the Global String Tension
Daniel Davies
We show that at large distances from an infinitely long global U(1) string, low energy Goldstone Bosons contribute a spatially dependent term to the energy density which is non-int…
Cardy's Conjecture and the Spectrum of Infrared Strongly-Coupled Quantum Field Theories
Daniel Davies
Cardy's conjecture about the evolution of the trace anomaly under renormalization group (RG) flows is re-interpreted as an exact, non-perturbative statement about the scaling dimen…
Quantum Solitons in any Dimension: Derrick's Theorem v. AQFT
Daniel Davies
A powerful tool for studying the behavior of classical field theories is Derrick's theorem: one may rule out the existence of localized inhomogeneous stable field configurations (s…
