General Two-Dimensional Supergravity from Poisson Superalgebras
M. Ertl, W. Kummer, T. Strobl
We provide the geometric actions for most general N=1 supergravity in two spacetime dimensions. Our construction implies an extension to arbitrary N. This provides a supersymmetriz…
Decay of an excited atom near an absorbing microsphere
Ho Trung Dung, Ludwig Knöll, Dirk-Gunnar Welsch
Spontaneous decay of an excited atom near a dispersing and absorbing microsphere of given complex permittivity that satisfies the Kramers-Kronig relations is studied, with special…
Third post-Newtonian dynamics of compact binaries: Noetherian conserved quantities and equivalence between the harmonic-coordinate and ADM-Hamiltonian formalisms
Vanessa de Andrade, Luc Blanchet, Guillaume Faye
A Lagrangian from which derive the third post-Newtonian (3PN) equations of motion of compact binaries (neglecting the radiation reaction damping) is obtained. The 3PN equations of…
Coupled cavities for enhancing the cross-phase modulation in electromagnetically induced transparency
T. Opatrny, D. -G. Welsch
We propose an optical double-cavity resonator whose response to a signal is similar to that of an Electromagnetically Induced Transparency (EIT) medium. A combination of such a dev…
Precanonical Quantization and the Schroedinger Wave Functional
I. V. Kanatchikov
A relation between the Schroedinger wave functional and the Clifford-valued wave function which appears in what we call precanonical quantization of fields and fulfills a Dirac-lik…
Pointlike Hopf defects in Abelian projections
Falk Bruckmann
We present a new kind of defect in Abelian Projections, stemming from pointlike zeros of second order. The corresponding topological quantity is the Hopf invariant pi_3(S^2) (rathe…
