Natural discrete differential calculus in physics
Carlo Rovelli, Václav Zatloukal
We sharpen a recent observation by Tim Maudlin: differential calculus is a natural language for physics only if additional structure, like the definition of a Hodge dual or a metri…
Casimir energy for two and three superconducting coupled cavities
L. Rosa, S. Avino, E. Calloni +16
In this paper we study the behavior of the Casimir energy of a "multi-cavity" across the transition from the metallic to the superconducting phase of the constituting plates. Our a…
The Good, the Bad, and the Ugly of Gravity and Information
Gerard 't Hooft, Steven B. Giddings, Carlo Rovelli +4
Various contenders for a complete theory of quantum gravity are at odds with each other. This is in particular seen in the ways they relate to information and black holes, and how…
Why do we remember the past and not the future? The 'time oriented coarse graining' hypothesis
Carlo Rovelli
Phenomenological arrows of time can be traced to a past low-entropy state. Does this imply the universe was in an improbable state in the past? I suggest a different possibility: p…
Relative information at the foundation of physics
Carlo Rovelli
Shannon's notion of relative information between two physical systems can function as foundation for statistical mechanics and quantum mechanics, without referring to subjectivism…
Why Gauge?
Carlo Rovelli
The world appears to be well described by gauge theories; why? I suggest that gauge is more than mathematical redundancy. Gauge-dependent quantities can not be predicted, but there…
A critical look at strings
Carlo Rovelli
This is an invited contribution to the Special Issue of "Foundations of Physics" titled "Forty Years Of String Theory: Reflecting On the Foundations". I have been asked to assess s…
Simple model for quantum general relativity from loop quantum gravity
Carlo Rovelli
New progress in loop gravity has lead to a simple model of `general-covariant quantum field theory'. I sum up the definition of the model in self-contained form, in terms accessibl…
The century of the incomplete revolution: searching for general relativistic quantum field theory
Carlo Rovelli
In fundamental physics, this has been the century of quantum mechanics and general relativity. It has also been the century of the long search for a conceptual framework capable of…
Barrett-Crane model from a Boulatov-Ooguri field theory over a homogeneous space
R. De Pietri, L. Freidel, K. Krasnov +1
Boulatov and Ooguri have generalized the matrix models of 2d quantum gravity to 3d and 4d, in the form of field theories over group manifolds. We show that the Barrett-Crane quantu…
The basis of the Ponzano-Regge-Turaev-Viro-Ooguri model is the loop representation basis
Carlo Rovelli
We show that the Hilbert space basis that defines the Ponzano-Regge- Turaev-Viro-Ooguri combinatorial definition of 3-d Quantum Gravity is the same as the one that defines the Loop…
Weaving a classical geometry with quantum threads
Abhay Ashtekar, Carlo Rovelli, Lee Smolin
Results that illuminate the physical interpretation of states of nonperturbative quantum gravity are obtained using the recently introduced loop variables. It is shown that: i) Whi…
Self Duality and Quantization
Abhay Ashtekar, Carlo Rovelli, Lee Smolin
Quantum theory of the free Maxwell field in Minkowski space is constructed using a representation in which the self dual connection is diagonal. Quantum states are now holomorphic…
A Loop Representation for the Quantum Maxwell Field
Abhay Ashtekar, Carlo Rovelli
Quantization of the free Maxwell field in Minkowski space is carried out using a loop representation and shown to be equivalent to the standard Fock quantization. Because it is bas…
Gravitons and Loops
Abhay Ashtekar, Carlo Rovelli, Lee Smolin
The recently proposed loop representation, used previously to find exact solutions to the quantum constraints of general relativity, is here used to quantize linearized general rel…
