Reviews of Modern Physics, 1999 I discuss the general principles underlying quantum field theory, and attempt to identify its most profound consequences. The deepest of these consequences result from the infinite number of degrees of freedom invoked to implement locality. I mention a few of its most striking successes, both achieved and prospective.

Relative Quantum Field Theory [PDF]
Communications in Mathematical Physics, 2014 We highlight the general notion of a relative quantum field theory, which occurs in several contexts. One is in gauge theory based on a compact Lie algebra, rather than a compact Lie group. This is relevant to the maximal superconformal theory in six dimensions.

Reverse Engineering Quantum Field Theory [PDF]
AIP Conf. Proc. 1508 (2012) 428-432, 2012 An approach to the foundations of quantum theory is advertised that proceeds by "reverse engineering" quantum field theory. As a concrete instance of this approach, the general boundary formulation of quantum theory is outlined.

Circuit complexity in quantum field theory [PDF]
Journal of High Energy Physics, 2017 Motivated by recent studies of holographic complexity, we examine the question of circuit complexity in quantum field theory. We provide a quantum circuit model for the preparation of Gaussian states, in particular the ground state, in a free scalar ...

The quantum theory of light. [PDF]
Philos Trans A Math Phys Eng SciWe present a brief introduction to the quantum theory of light as it is understood in the field of quantum optics. Our aim is not to review the topic, which would require a very extensive article (or even a book of several volumes) but rather to provide ...

Bohmian Mechanics and Quantum Field Theory [PDF]
Phys.Rev.Lett. 93 (2004) 090402, 2003 We discuss a recently proposed extension of Bohmian mechanics to quantum field theory. For more or less any regularized quantum field theory there is a corresponding theory of particle motion, which in particular ascribes trajectories to the electrons or whatever sort of particles the quantum field theory is about.
