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…
