Anomalies and Invertible Field Theories

, 2014
We give a modern geometric viewpoint on anomalies in quantum field theory and illustrate it in a 1-dimensional theory: supersymmetric quantum mechanics.

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]

, 2009
The incompatibility between GR and QM is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - QM gives a universally valid basis for the description of all natural systems, then ...

AdS_2 Supergravity and Superconformal Quantum Mechanics

, 2003
We investigate the asymptotic dynamics of topological anti-de Sitter supergravity in two dimensions. Starting from the formulation as a BF theory, it is shown that the AdS_2 boundary conditions imply that the asymptotic symmetries form a super-Virasoro ...

Glimpse on the relationship between Feynman integral and integrable system [PDF]

, 2004
We briefly review recent attempts to relate the concept of Feynman integral and integrable systems. This constitutes an endeavour on our part in making the Feynman path integral into a mathematically meaningful ...

Effects on the Non-Relativistic Dynamics of a Charged Particle Interacting with a Chern-Simons Potential

, 2013
The hydrogen atom in two dimensions, described by a Schr\"odinger equation with a Chern-Simons potential, is numerically solved. Both its wave functions and eigenvalues were determined for small values of the principal quantum number $n$.

String Theory - Nomological Unification and the Epicycles of the Quantum Field Theory Paradigm [PDF]

, 2011
String Theory is the result of the conjunction of three conceptually independent elements: (i) the metaphysical idea of a nomological unity of the forces, (ii) the model-theoretical paradigm of Quantum Field Theory, and (iii) the conflict resulting from ...

Noncommutativity and Discrete Physics

, 1997
The purpose of this paper is to present an introduction to a point of view for discrete foundations of physics. In taking a discrete stance, we find that the initial expression of physical theory must occur in a context of noncommutative algebra and ...

The Dimensions of Field Theory : From Particles to Strings [PDF]

, 1999
This is an editorial summary of the contents of a Book comprising a set of Articles by acknowledged experts dealing with the impact of Field Theory on major areas of physics (from elementary particles through condensed matter to strings), arranged ...

Some Physical Aspects of Liouville String Dynamics [PDF]

, 1994
We discuss some physical aspects of our Liouville approach to non-critical strings, including the emergence of a microscopic arrow of time, effective field theories as classical ``pointer'' states in theory space, $CPT$ violation and the possible ...
