The standard model of particle physics has the following key features: • As a theory of elementary particles, it incorporates relativity and quantum mechanics, and therefore it is based on quantum field theory. • Its predictive power rests on the regularisation of divergent quantum corrections and th ...

(Quantumness in the context of) Resource Theories
... Quantum information theory is novel in that it seeks to apply techniques from computer science to understand the laws of physics. The types of questions one asks are often different to the questions physicists used to ask. We are interested in finding out what is possible given some resources or some ...

Coherent State Path Integrals
... Therefore the path integral for a system of non-relativistic bosons (with chemical potential µ) has the same form os the path integral of the charged scalar field we discussed before except that the action is first order in time derivatives. th fact that the field is complex follows from the require ...

Canonical Quantum Gravity as a Gauge Theory with Constraints
... Thusly, our theory will be formulated most naturally in terms of a gauge theory, a class of field theories that are in some ways generalizations of Maxwell’s electrodynamics. Taking the place of the matter fields in this gauge theory will be the “field of frames” eI , or, a choice of four arrows at ...
