d-dimensional unitarity cut method
We develop a unitarity method to compute one-loop amplitudes with massless propagators in d=4-2*epsilon dimensions. We compute double cuts of the loop amplitudes via a decomposi...
Scattering Amplitudes with Open Loops
We introduce a new technique to generate scattering amplitudes at one loop. Traditional tree algorithms, which handle diagrams with fixed momenta, are promoted to generators of ...
A matrix-operator approach to reflection high-energy electron diffraction theory
The amplitudes of beams reflected from a crystal surface by high-energy electrons are expressed in terms of matrix operators based on Bloch waves. The solution is derived in ter...
Geometry, Topology and Physics
Differential geometry and topology have become essential tools for many theoretical physicists. In particular, they are indispensable in theoretical studies of condensed matter ...
Spontaneous Symmetry Breakdown without Massless Bosons
We examine a simple relativistic theory of two scalar fields, first discussed by Goldstone, in which as a result of spontaneous breakdown of $U(1)$ symmetry one of the scalar bo...
