Quantum geometry with intrinsic local causality
Fotini Markopoulou, Lee Smolin
The space of states and operators for a large class of background independent theories of quantum spacetime dynamics is defined. The SU(2) spin networks of quantum general relativi…
Covariant quantization of membrane dynamics
Lee Smolin
A Lorentz covariant quantization of membrane dynamics is defined, which also leaves unbroken the full three dimensional diffeomorphism invariance of the membrane. Among the applica…
Coevolution of membranes and channels: A possible step in the origin of life
Saint Clair Cemin, Lee Smolin
We propose a scenario for the origin of life based on the coevolution of lipid bilayer vesicles and protein channels.
A possible solution to the problem of time in quantum cosmology
Stuart Kauffman, Lee Smolin
We argue that in classical and quantum theories of gravity the configuration space and Hilbert space may not be constructible through any finite procedure. If this is the case then…
Chern-Simons theory in 11 dimensions as a non-perturbative phase of M theory
Lee Smolin
A Chern-Simons theory in 11 dimensions, which is a piece of the 11 dimensional supergravity action, is considered as a quantum field theory in its own right. We conjecture that it…
The future of spin networks
Lee Smolin
The roles that spin networks play in gauge theories, quantum gravity and topological quantum field theory are briefly described, with an emphasis on the question of the relationshi…
Causal evolution of spin networks
Fotini Markopoulou, Lee Smolin
A new approach to quantum gravity is described which joins the loop representation formulation of the canonical theory to the causal set formulation of the path integral. The theor…
