Four Dimensional Superconformal Field Theories From String Theory. [PDF]
, 2016 PhDIn this work, we discuss four dimensional SCFTs which descend from string theory and M-theory. These SCFTs arise naturally from stacks of string and M- theory branes and are useful tools for studying various phenomena in four dimensional quantum ...

Jacobi Identity Anomaly in Closed String Field Theory [PDF]
Progress of Theoretical Physics, 1991 The Jacobi identity, which is an indispensable property for gauge invariant closed string field theory, is apparently broken in cases where one of the four legs of the identity has vanishing string-length. This phenomenon contradicts the general proof of the identity valid at the critical dimension.

Relativistic hydrodynamics with the parity anomaly
Journal of High Energy Physics, 2022 We consider the hydrodynamic regime of a 2+1 dimensions QFT with the parity anomaly. Beyond the known constraints from positivity of entropy production, we show that the anomaly inflow mechanism, from a corresponding bulk SPT phase, together with ...

The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills [PDF]
Nuclear Physics B, 1994 Many field theories of physical interest have configuration spaces consisting of disconnected components. Quantum mechanical amplitudes are then expressed as sums over these components. We use the Faddeev-Popov approach to write the terms in this topological expansion as moduli space integrals. A cut-off is needed when these integrals diverge.

Scale anomalies, states, and rates in conformal field theory
Journal of High Energy Physics, 2017 This paper presents two methods to compute scale anomaly coefficients in conformal field theories (CFTs), such as the c anomaly in four dimensions, in terms of the CFT data.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

The UV fate of anomalous U(1)s and the Swampland
Journal of High Energy Physics, 2020 Massive U(1) gauge theories featuring parametrically light vectors are suspected to belong in the Swampland of consistent EFTs that cannot be embedded into a theory of quantum gravity.

Mirror Symmetry and Other Miracles in Superstring Theory [PDF]
, 2010 The dominance of string theory in the research landscape of quantum gravity physics (despite any direct experimental evidence) can, I think, be justified in a variety of ways.

Journal of High Energy Physics, 2018 The linearized Einstein equation describing graviton propagation through a chiral medium appears to be helicity dependent. We analyze features of the corresponding spectrum in a collision-less regime above a flat background. In the long wave-length limit,

Cancellation of the Lorentz anomaly of string field theory in light-cone gauge
Nuclear Physics B, 1990 Abstract We study the path-integral measure of string fields in the bosonic open-closed interacting string field theory in light-cone gauge. The Lorentz anomaly of the path-integral measure cancels the Lorentz non-invariant terms of the classical string field action. Thus the theory is shown to be Lorentz invariant at the one-loop level. The one-loop
