scalar-tensor theories for traceless matter field

ω(φ) → ∞ limit of scalar tensor theories are studied for traceless matter source. It is shown that the limit ω(φ) → ∞ does not reduce a scalar tensor theory to GR. An exact radiation solution of scalar tensor cosmology under modified Nordtvedt conditions is obtained for flat Friedmann universe. PACS numbers: 04.50. +h

Describing Nuclear Matter with Effective Field Theories

Nuclear forces have been studied in depth over the past fifty years, leading to excellent phenomenological descriptions. A recent resurgence of interest in this field has been fueled by the promise of systematic results from an effective field theory (EFT) analysis [1]. EFT techniques adapted to many-body systems may give new insight into the properties of nuclei and their connection to QCD. Th...

Supersymmetric field theories and generalized cohomology

This paper is a survey of our mathematical notions of Euclidean field theories as models for (the cocycles in) a cohomology theory. This subject was pioneered by Graeme Segal [Se1] who suggested more than two decades ago that a cohomology theory known as elliptic cohomology can be described in terms of 2-dimensional (conformal) field theories. Generally what we are looking for are isomorphisms ...
