چکیده

We analyze in full-detail the geometric structure of covariant phase space (CPS) any local field theory defined over a space-time with boundary. To this end, we introduce new frame: "relative bicomplex framework". It is result merging an extended version framework" (initially developed context algebraic topology by R.~Bott and L.W.~Tu 1980s to deal boundaries) variational framework (the differential arena for calculus). The relative natural one theories boundary contributions, including corner contributions. In fact, prove formal equivalence between non-relative same no With these tools at hand, endow solutions (pre)symplectic canonically associated action which, general, has also study symmetries construct, large group them, their Noether currents, charges. Moreover, completely characterize arbitrariness (or lack thereof fiber bundles contractible fibers) constructions. This clarifies many misconceptions about role terms CPS description theory. Finally, provide what call CPS-algorithm construct aforementioned apply it some relevant examples.

Euler characteristic and the first Chern number in the covariant phase space formulation of string theory

Using a covariant description of the geometry of deformations for extendons, it is shown that the topological corrections for the string action associated with the Euler characteristic and the first Chern number of the normal bundle of the worldsheet, although do not give dynamics to the string, modify the symplectic properties of the covariant phase space of the theory. Future extensions of th...

Symplectically Covariant Schrödinger Equation in Phase Space

A classical theorem of Stone and von Neumann says that the Schrödinger representation is, up to unitary equivalences, the only irreducible representation of the Heisenberg group on the Hilbert space of square-integrable functions on configuration space. Using the Wigner-Moyal transform we construct an irreducible representation of the Heisenberg group on a certain Hilbert space of square-integr...

Covariant Majorana Formulation of Electrodynamics

We construct an explicit covariant Majorana formulation of Maxwell electromagnetism which does not make use of vector 4-potential. This allows to write a “Dirac” equation for the photon containing all the known properties of it. In particular, the spin and (intrinsic) boost matrices are derived and the helicity properties of the photon are studied.

The Geometric Phase and Ray Space Isometries

We study the behaviour of the geometric phase under isometries of the ray space. This leads to a better understanding of a theorem first proved byWigner: isometries of the ray space can always be realised as projections of unitary or anti-unitary transformations on the Hilbert space. We suggest that the construction involved in Wigner’s proof is best viewed as an use of the Pancharatnam connect...

Covariant Phase Space Formulations of Superparticles and Supersymmetric WZW Models

We present new covariant phase space formulations of superparti-cles moving on a group manifold, deriving the fundamental Poisson brackets and current algebras. We show how these formulations naturally generalise to the supersymmetric Wess-Zumino-Witten models.
