Non-locality and gauge freedom in Deutsch and Hayden'sformulation of quantum mechanics
non-locality gauge freedom
2008/4/22
Deutsch and Hayden have proposed an alternative formulation of quantum mechanics which is completely local. We argue that their proposal must be understood as having a form of `gauge freedom' accordin...
Classically, a gauge potential was merely a convenient device for generating a corresponding gauge field. Quantum-mechanically, a gauge potential lays claim to independent status as a further feature ...
What is the significance of gauge freedom? This paper makes a start on answering this and other interpretative questions about classical and quantum gauge theories by situating classical gauge freedom...
The non-relativistic limits of the Maxwell and Dirac equations: the role of Galilean and gauge invariance
Non-relativistic limit Maxwell equations Dirac equations Pauli equation
2008/4/21
The aim of this paper is to illustrate four properties of the non-relativistic limits of relativistic theories: (a) that a massless relativistic field may have a meaningful non-relativistic limit, (b)...
Holism and Structuralism in U(1) Gauge Theory
Gauge theories gauge symmetry ontological nderdetermination

After decades of neglect philosophers of physics have discovered gauge theories--arguably the paradigm of modern field physics--as a genuine topic for foundational and philosophical research. Incident...
Gravity and Gauge Theory
Gauge Theory Gravity
2008/4/14
Gauge theories are theories that are invariant under a characteristic group of "gauge" transformations. General relativity is invariant under transformations of the diffeomorphism group. This has prom...
This paper is an analysis of the geometrical interpretation of local gauge symmetry for theories of the Yang-Mills type.
General Covariance, Gauge Theories and the Kretschmann Objection.
the Kretschmann Objection Gauge Theories General Covariance
2008/4/14
How can we reconcile two claims that are now both widely accepted: Kretschmann's claim that a requirement of general covariance is physically vacuous and the standard view that the general covariance ...
Gauge Theories and Holisms
holism gauge nonseparability
2008/4/14
Those looking for holism in contemporary physics have focused their attention primarily on quantum entanglement. But some gauge theories arguably also manifest the related phenomenon of nonseparabilit...
According to conventional wisdom, local gauge symmetry is not a symmetry of nature, but an artifact of how our theories represent nature. But a study of the so-called theta-vacuum appears to refute th...

The constrained Hamiltonian formalism is recommended as a means for getting a grip on the concepts of gauge and gauge transformation. This formalism makes it clear how the gauge concept is relevant to...
Gauge Gravity and the Unification of Natural Forces
the Unification of Natural Forces Gauge Gravity
2008/4/14
Physics seems to tell us that there are four fundamental force-fields in nature: the gravitational, the electromagnetic, the weak, and the strong force-field (or interactions). But it also seems to te...
Curve It, Gauge It, or Leave It? Practical Underdetermination in Gravitational Theories

2008/4/11
Four empirically equivalent versions of general relativity,
namely standard GR, Lorentz-invariant gravitational theory,
and the gravitational gauge theories of the Lorentz and
translation groups, a...
In a recent paper in the British Journal for the Philosophy of Science, Kosso discussed the observational status of continuous symmetries of physics. While we are in broad agreement with his approach,...
An Elementary Notion of Gauge Equivalence
Gauge Equivalence Asymptotic Boundary Conditions
2008/4/10
An elementary notion of gauge equivalence is introduced that does not require any Lagrangian or Hamiltonian apparatus. It is shown that in the special case of theories, such as general relativity, who...
