A group theoretical approach to causal structures and positive energy on spacetimes
Christophe Patricot
This article presents a precise description of the interplay between the symmetries of a quantum or classical theory with spacetime interpretation, and some of its physical propert…
Newton-Hooke spacetimes, Hpp-waves and the cosmological constant
G. W. Gibbons, C. E. Patricot
We show explicitly how the Newton-Hooke groups act as symmetries of the equations of motion of non-relativistic cosmological models with a cosmological constant. We give the action…
On Quantum Operations as Quantum States
Pablo Arrighi, Christophe Patricot
We formalize the correspondence between quantum states and quantum operations isometrically, and harness its consequences. This correspondence was already implicit in the various p…
The Conal representation of Quantum States and Non Trace-Preserving Quantum Operations
Pablo Arrighi, Christophe Patricot
We represent generalized density matrices of a -complex dimensional quantum system as a subcone of a real pointed cone of revolution in , or indeed a Minkowski…
A Note on the correspondence between Qubit Quantum Operations and Special Relativity
Pablo Arrighi, Christophe Patricot
We exploit a well-known isomorphism between complex hermitian matrices and , which yields a convenient real vector representation of qubit states. Because…
