Schwinger functions and light-quark bound states (2007)
Bhagwat, M. S., Hoell, A., Krassnigg, A., Roberts, C. D., Wright, S. V.
We examine the applicability and viability of methods to obtain knowledge about bound-states from information provided solely in Euclidean space. Rudimentary methods can be adequate if one only...
Observations of plasmons in warm dense matter (2007)
Glenzer, SH, Landen, OL, Neumayer, P, Lee, RW, Widmann, K, Pollaine, SW, ...
We present the first collective x-ray scattering measurements of plasmons in solid-density plasmas. The forward scattering spectra of a laser-produced narrow-band x-ray line from isochorically heated...

Hypernetted chain calculations for two-component plasmas (2006)
Schwarz, V., Bornath, Th., Kraeft, W. D., Glenzer, S., Hoell, A., Redmer, R.
We have performed HNC calculations for dense beryllium plasma as studied experimentally using x-ray Thomson scattering, recently. We treated non-equilibrium situations with different electron and ion...
Thomson scattering from near-solid density plasmas using soft x-ray free electron lasers (2006)
We propose a collective Thomson scattering experiment at the VUV free electron laser facility at DESY (FLASH) which aims to diagnose warm dense matter at near-solid density. The plasma region of...
Hadron Physics and Dyson-Schwinger Equations (2006)
Hoell, A., Roberts, C. D., Wright, S. V.
Detailed investigations of the structure of hadrons are essential for understanding how matter is constructed from the quarks and gluons of QCD, and amongst the questions posed to modern hadron...
Schwinger functions and light-quark bound states, and sigma terms (2005)
Hoell, A., Maris, P., Roberts, C. D., Wright, S. V.
We explore the viability of using solely spacelike information about a Schwinger function to extract properties of bound states. In a concrete example it is not possible to determine properties of...
Sigma Terms of Light-Quark Hadrons (2005)
Flambaum, V. V., Hoell, A., Jaikumar, P., Roberts, C. D., Wright, S. V.
A calculation of the current-quark mass dependence of hadron masses can help in using observational data to place constraints on the variation of nature's fundamental parameters. A hadron's...
Electromagnetic properties of ground and excited state pseudoscalar mesons (2005)
Hoell, A., Krassnigg, A., Maris, P., Roberts, C. D., Wright, S. V.
The axial-vector Ward-Takahashi identity places constraints on particular properties of every pseudoscalar meson. For example, in the chiral limit all pseudoscalar mesons, except the Goldstone mode,...
On Nucleon Electromagnetic Form Factors: A Pre'cis (2005)
Hoell, A, Alkofer, R., Kloker, M., Krassnigg, A., Roberts, C. D., Wright, S. V.
Electron scattering at large Q^2 probes a nucleon's quark core. This core's contribution to electromagnetic form factors may be calculated using Poincare' covariant Faddeev amplitudes combined with a...
On Nucleon Electromagnetic Form Factors (2004)
Alkofer, R., Hoell, A., Kloker, M., Krassnigg, A., Roberts, C. D.
A Poincare' covariant Faddeev equation, which describes baryons as composites of confined-quarks and -nonpointlike-diquarks, is solved to obtain masses and Faddeev amplitudes for the nucleon and...
On the complexion of pseudoscalar mesons (2004)
Hoell, A., Krassnigg, A., Roberts, C. D., Wright, S. V.
A strongly momentum-dependent dressed-quark mass function is basic to QCD. It is central to the appearance of a constituent-quark mass-scale and an existential prerequisite for Goldstone modes....
Pseudoscalar Meson Radial Excitations (2004)
Hoell, A., Krassnigg, A., Roberts, C. D.
Goldstone modes are the only pseudoscalar mesons to possess a nonzero leptonic decay constant in the chiral limit when chiral symmetry is dynamically broken. The decay constants of their radial...
Aspects and consequences of a dressed-quark-gluon vertex (2004)
Bhagwat, M. S., Hoell, A., Krassnigg, A., Roberts, C. D., Tandy, P. C.
Features of the dressed-quark-gluon vertex and their role in the gap and Bethe-Salpeter equations are explored. It is argued that quenched lattice data indicate the existence of net attraction in the...
Butter, Karen, Hoell, A., Wiedenmann, A., Petukhov, A.V.
This paper describes the characterization of dispersions of oleic-acid-coated magnetic iron particles by small-angle neutron and X-ray scattering (SANS and SAXS). Both oxidized and non-oxidized...
DSEs and pseudoscalar mesons: an aperc,u (2003)
Hoell, A., Krassnigg, A., Roberts, C. D.
An hallmark of present-day Dyson-Schwinger equation applications in hadron physics is the existence of a systematic and symmetry preserving truncation scheme. This enables the proof of exact results;...
Covariant Linear Response Theory of Relativistic QED Plasmas (2002)
Hoell, A., Morozov, V. G., Roepke, G.
We start from the QED Lagrangian to describe a charged many-particle system coupled to the radiation field. A covariant density matrix approach to kinetic theory of QED plasmas, subjected to a strong...
Hoell, A., Morozov, V., Roepke, G.
Starting from a general relativistic kinetic equation, a self-consistent mean-field equation for fermions is derived within a covariant density matrix approach of QED plasmas in strong external...
Hoell, A., Morozov, V. G., Roepke, G.
We develop a covariant density matrix approach to kinetic theory of QED plasmas subjected into a strong external electromagnetic field. A canonical quantization of the system on space-like...
Analysis of chiral and thermal susceptibilities (1998)
Blaschke, D., Hoell, A., Roberts, C. D., Schmidt, S.
We calculate the chiral and thermal susceptibilities for two confining Dyson-Schwinger equation models of QCD with two light flavours, a quantitative analysis of which yields the critical exponents,...
