Supersymmetry Partial Breaking and Tadpole Anomaly
We consider the extension of the effective
supersymmetric model of ; and study the
explicit relationship between partial breaking of supersymmetry
constraint and D3 brane tadpole anomaly of type IIB string on Calabi-Yau
threefolds in presence of H and H fluxes. We also comment on
supersymmetry breaking in the particular Maxwell
theory; and study its interpretation in connection with the tadpole anomaly
with extra localized flux sources.Comment: LaTex 37 page
Symplectic Fluctuations for Electromagnetic Excitations of Hall Droplets
We show that the integer quantum Hall effect systems in plane, sphere or
disc, can be formulated in terms of an algebraic unified scheme. This can be
achieved by making use of a generalized Weyl--Heisenberg algebra and
investigating its basic features. We study the electromagnetic excitation and
derive the Hamiltonian for droplets of fermions on a two-dimensional Bargmann
space (phase space). This excitation is introduced through a deformation
(perturbation) of the symplectic structure of the phase space. We show the
major role of Moser's lemma in dressing procedure, which allows us to eliminate
the fluctuations of the symplectic structure. We discuss the emergence of the
Seiberg--Witten map and generation of an abelian noncommutative gauge field in
the theory. As illustration of our model, we give the action describing the
electromagnetic excitation of a quantum Hall droplet in two-dimensional
manifold.Comment: 23 page
Shape invariant potential formalism for photon-added coherent state construction
An algebro-operator approach, called shape invariant potential method, of
constructing generalized coherent states for photon-added particle system is
presented. Illustration is given on Poschl-Teller potential
