Dirichlet branes and a cohomological definition of time flow
J. M. Isidro, P. Fernandez de Cordoba
Dirichlet branes are objects whose transverse coordinates in space are matrix-valued functions. This leads to considering a matrix algebra or, more generally, a Lie algebra, as the…

Wigner functions, Fresnel optics, and symplectic connections on phase space
J. M. Isidro
We prove that Wigner functions contain a symplectic connection. The latter covariantises the symplectic exterior derivative on phase space. We analyse the role played by this conne…

Quantum mechanics as a spontaneously broken gauge theory on a U(1) gerbe
J. M. Isidro
Any quantum-mechanical system possesses a U(1) gerbe naturally defined on configuration space. Acting on Feynman's kernel exp(iS/h), this U(1) symmetry allows one to arbitrarily pi…
