Exact solutions of Dyson-Schwinger equations for iterated one-loop integrals and propagator-coupling duality
D. J. Broadhurst, D. Kreimer
The Hopf algebra of undecorated rooted trees has tamed the combinatorics of perturbative contributions, to anomalous dimensions in Yukawa theory and scalar theory, from all n…
A Scaling Law for the Energy Levels of a Nonlinear Schrodinger Equation
R. Hasson, D. Richards
It is shown that the energy levels of the one-dimensional nonlinear Schrodinger, or Gross-Pitaevskii, equation with the homogeneous trap potential , , obey an appr…
Semiclassical trace formulae using coherent states
B. Mehlig, M. Wilkinson
We derive semiclassical trace formulae including Gutzwiller's trace formula using coherent states. This formulation has several advantages over the usual coordinate-space formulati…
su(2) and su(1,1) displaced number states and their nonclassical properties
Hongchen Fu, Xiaoguang Wang, Chong Li +1
We study su(2) and su(1,1) displaced number states. Those states are eigenstates of density-dependent interaction systems of quantized radiation field with classical current. Those…
OAO1657-415 : A `Missing Link' in High Mass X-ray Binaries?
D. H. Maxwell, A. J. Norton, P. Roche
OAO1657-415 is only the seventh eclipsing X-ray pulsar known and therefore has the potential to yield only the seventh mass of a neutron star in an X-ray binary. Here we report pho…
A search for possible interactions between ejections from GRS 1915+105 and the surrounding interstellar medium
S. Chaty, L. F. Rodriguez, I. F. Mirabel +5
We have observed an extended region surrounding the first discovered galactic superluminal source GRS 1915+105, seeking evidence of interaction between the relativistic ejecta of t…
