In a background independent theory without boundary, physical observables may be defined with respect to dynamical reference systems. However, I argue here that there may be a symmetry that exchanges the degrees of freedom of the physical frame of reference with the other degrees of freedom which are measured relative to that frame. This symmetry expresses the fact that the choice of frame of reference is arbitrary, but the same laws apply to all, including observer and observed. It is then… 

On Jordan–Clifford Algebras, Three Fermion Generations with Higgs Fields and a Model

Previously we have shown that the algebra J3[C ⊗ O] ⊗ C (4,C), given by the tensor product of the complex exceptional Jordan J3[C⊗O] and the complex Clifford algebra C (4,C), can describe all of the



Quantum mechanics and the covariance of physical laws in quantum reference frames

A relational formalism is used to quantise a reference frame and the covariance of physical laws under transformations between such quantum reference frames is shown.

Switching quantum reference frames in the N-body problem and the absence of global relational perspectives

Given the importance of quantum reference systems to both quantum and gravitational physics, it is pertinent to develop a systematic method for switching between the descriptions of physics relative

Switching Internal Times and a New Perspective on the ‘Wave Function of the Universe’

Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates,

Quantum theory from quantum gravity

We provide a mechanism by which, from a background-independent model with no quantum mechanics, quantum theory arises in the same limit in which spatial properties appear. Starting with an arbitrary

A change of perspective: switching quantum reference frames via a perspective-neutral framework

A perspective-neutral structure is developed, which contains all frame perspectives at once and via which they are changed, and a new take on the relation between a `quantum general covariance' and the diffeomorphism symmetry in quantum gravity is suggested.

Metastring theory and modular space-time

A bstractString theory is canonically accompanied with a space-time interpretation which determines S-matrix-like observables, and connects to the standard physics at low energies in the guise of

Relativistic Quantum Reference Frames: The Operational Meaning of Spin.

An operational procedure offers a concrete way of testing the relativistic features of the spin, and opens up the possibility of devising quantum information protocols for spin in the special-relativistic regime.

Time reference frames and gravitating quantum clocks

A framework for "time reference frames," in which events are defined in terms of quantum operations with respect to a quantum clock, is developed, which finds that, when clocks and quantum systems interact gravitationally, the temporal localisability of events becomes relative, depending on the time reference frame.

Statistical Dynamics of Global Unitary Invariant Matrix Models as Pre-Quantum Mechanics

We consider the classical dynamics of bosonic and fermionic matrix variables in complex Hilbert space, defined by a trace action, assuming cyclic invariance under the trace and the presence of a
