Path Integrals and Anomalies in Curved Space

, 2006
Path integrals provide a powerful method for describing quantum phenomena, first introduced in physics by Dirac and Feynman. This book introduces the quantum mechanics of particles that move in curved space by employing the path integral method and uses ...

Anomalies and the Green-Schwarz Mechanism

Anomalies are a very powerful tool in constraining theories beyond the standard model. We give a pedagogical overview of some topics illustrating the important role played by spacetime anomalies in string theory.

Topics in string theory and quantum gravity

, 1992
These are the lecture notes for the Les Houches Summer School on Quantum Gravity held in July 1992. The notes present some general critical assessment of other (non-string) approaches to quantum gravity, and a selected set of topics concerning what we ...

Aspects of generalised symmetries of four-dimensional field theories

Symmetry is a foundational concept in quantum field theory, essential for the construction of gauge theories, organising particles into multiplets, and as a link between microscopic and macroscopic physics. Symmetries are related to conserved quantities,

Heterotic global anomalies and torsion Witten index

Journal of High Energy Physics, 2022
We study the structure of anomalies in general heterotic string theories by considering general 2-dimensional $\mathcal{N}=(0,1)$ supersymmetric quantum field theories (SQFTs), without assuming conformal invariance nor the correct central charges.

General Quantization Anomaly in Bosonic String Theory Interacting with Background Gravitational Field

1996
The problem of anomaly at the generalized canonical quantization (BFV -— quantization) of bosonic string coupled to background fields is considered. The equation for symbol of anomaly operator is obtained. The general solution of this equation is found and the arbitrariness in general form of anomaly is investigated.
