Frame-like Geometry of Double Field Theory
Frame-like Geometry Double Field Theory
font style='font-size:12px;'>
2010/12/24
We relate two formulations of the recently constructed double field theory to a frame-like geometrical formalism developed by Siegel. A self-contained presentation of this formalism is given, includi...
A thermal field theory derivation of the source term induced by a fast parton from the quark energy-momentum tensor

I derive the distribution of energy and momentum transmitted from a fast parton to a medium of
thermalized quarks, or the source term, in perturbative thermal field theory directly from the quark ene...

2010/11/23
Topological phases of matter are described universally by topological eld theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg eld theories.We propose th...

2010/12/20
Recently, a generally covariant reformulation of 2 dimensional flat spacetime free scalar field theory known as Parameterised Field The-ory was quantized using Loop Quantum Gravity (LQG) type ‘polymer...

These notes are an expanded version of lectures given at the Croatian School on Black Holes at
Trpanj, June 21-25, 2010. The aim is to provide a practical introduction to quantum field theory in curv...
Proof of the Borwein-Broadhurst conjecture for a dilogarithmic integral arising in quantum field theory

Borwein and Broadhurst, using experimental-mathematics techniques, in 1998 identified numerous hyperbolic 3-manifolds whose volumes are rationally related to values of various Dirichlet L series $\te...
Riemann-Hilbert Problem and Quantum Field Theory: Integrable Renormalization, Dyson-Schwinger Equations
Riemann-Hilbert Problem Quantum Field Theory
font style='font-size:12px;'>
2010/11/19
In the first purpose, we concentrate on the theory of quantum integrable systems underlying the Connes-Kreimer approach. We introduce a new family of Hamiltonian systems depended on the perturbative ...

2010/12/20
In these lectures we consider some topics of Quantum Field Theory in Curved Space. In the first one particle creation in curved space is studied from a mathematical point of view, especially, particle...
Field theory on the light-front
Field theory light-front
font style='font-size:12px;'>
2011/1/7
We present a general framework to study relativistic compound systems in a Hamiltonian formalism. This formalism is based on the explicitly covariant formulation of light-front dynamics, with a decomp...

This is a brief overview of work done by Ian Anderson, Mark Fels, and myself on symmetry reduction of Lagrangians and Euler-Lagrange equations, a subject closely related to Palais’ Principle of Symmet...

2010/11/9
We show that the combinatorial numbers known as {\em Bell numbers} are generic in quantum physics. This is because they arise in the procedure known as {\em Normal ordering} of bosons, a procedure wh...

2011/1/7
A new microscopic nucleon-nucleon (NN) interaction has been derived for the first time from
the popular relativistic mean field theory (RMFT) Lagrangian. The NN interaction so obtained
remarkably re...
