Galilean Invariant

We consider a generalization of non-relativistic Schrödinger–Higgs Lagrangian by introducing a nonstandard kinetic term. We show that this model is Galilean invariant, we construct the conserved charges associated to the symmetries and realize the algebra of the Galilean group. In addition, we study the model in the presence of a gauge field. We also show that the gauged model is Galilean invariant. Finally, we explore relations between the twin models and their solutions.

Vacuum Polarization Tensor

The one-loop vacuum polarization tensor in noncommutative spinor QED in two dimensions is computed. A first-order formalism is used to simplify the interaction vertices for the vector field. Although the form of the gauge field-spinor interaction is chosen so as to vanish at tree level, as the noncommuting parameter goes to zero, the vacuum polarization is nontrivial in this limit.

Θ Vacuum

In the framework of the minimal quantization method, the residual “longitudinal” vacuum dynamics of the Abelian gauge field, which is described by a new pair of canonical variables, is revealed. This dynamics is shown to give origin to the θ vacuum, thus providing a field analogy of the Josephson effect. The destructive interference of the topological phases — that the fermion fields are shown to acquire — is considered as a reason for the charge screening in the two-dimensional massless QED.

Gauge Algebra

The action of the N=1 spinning string is shown to be the action of simple conformal supergravity in two dimensions. The constraints read R(P)=R(M)=R(D)=R(Q)=0 and τντµϕν= fμν - ½ gμν f = 0, where ϕμ and fμm are the conformal gravitino and boost field. In the N=2 theory, a new gauge field is found which is needed to close the gauge algebra.

Bad Company

AbstractWe characterize Doris's anti-reflectivist, collaborativist, valuational theory along two dimensions. The first dimension is socialentanglement, according to which cognition, agency, and selves are socially embedded. The second dimension isdisentanglement, the valuational element of the theory that licenses the anchoring of agency and responsibility in distinct actors. We then present an issue for the account: theproblem of bad company.
