Fluctuating forces on a rigid circular cylinder in confined flow
- A. Richter, E. Naudascher
- Physics
- 7 December 1976
The fluctuating lift and drag acting on a long, rigidly supported circular cylinder placed symmetrically in a narrow rectangular duct were investigated for various blockage percentages over a wide… Expand
Random matrices and chaos in nuclear physics: Nuclear reactions
- G. E. Mitchell, A. Richter, H. Weidenmueller
- Physics
- 14 January 2010
The application of random-matrix theory (RMT) to compound-nucleus (CN) reactions is reviewed. An introduction into the basic concepts of nuclear scattering theory is followed by a survey of… Expand
Structure of the Hoyle state in 12C.
- M. Chernykh, H. Feldmeier, T. Neff, P. von Neumann-Cosel, A. Richter
- Physics, Medicine
- Physical review letters
- 19 January 2007
The first excited 0(+) state in 12C (Hoyle state) has been predicted to be a dilute self-bound gas of bosonic alpha particles, similar to a Bose-Einstein condensate. To clarify this conjecture,… Expand
Experimental observation of the topological structure of exceptional points.
- C. Dembowski, H. Graef, +4 authors A. Richter
- Physics, Medicine
- Physical review letters
- 29 January 2001
We report on a microwave cavity experiment where exceptional points (EPs), which are square root singularities of the eigenvalues as function of a complex interaction parameter, are encircled in the… Expand
Incorporating diffuse scattering in geometry-based stochastic MIMO channel models
- J. Salmi, J. Poutanen, +4 authors A. Molisch
- Mathematics
- Proceedings of the Fourth European Conference on…
- 12 April 2010
This paper introduces a model for incorporating the influence of the diffuse scattering in the MIMO radio propagation channel to the popular geometry-based stochastic channel models (GSCM). The… Expand
Observation of orbital magnetic dipole strength in the actinide nuclei 232Th and 238U
- R. Heil, H. Pitz, +7 authors P. V. Brentano
- Physics
- 4 January 1988
Abstract Precise experimental information has been obtained on the distribution of orbital M1 strength using high resolution nuclear resonance fluorescence and inelastic electron scattering. We… Expand
Probing the nuclear magnetic dipole response with electrons, photons and hadrons☆
- A. Richter
- Physics
- 1995
Abstract In the first part of this lecture recent developments in the field of magnetic dipole excitations in heavy deformed nuclei are discussed by using electromagnetic and hadronic probes of… Expand
Wave dynamical chaos in a superconducting three-dimensional Sinai billiard
- H. Alt, C. Dembowski, +5 authors T. Weiland
- Physics
- 25 June 1997
Based on very accurate measurements performed on a superconducting microwave resonator shaped like a desymmetrized three-dimensional (3D) Sinai billiard, we investigate for the first time spectral… Expand
Exceptional points in a microwave billiard with time-reversal invariance violation.
- B. Dietz, H. L. Harney, Oleg N. Kirillov, M. Miski-Oglu, A. Richter, F. Schaefer
- Physics, Medicine
- Physical review letters
- 16 August 2010
We report on the experimental study of an exceptional point (EP) in a dissipative microwave billiard with induced time-reversal invariance (T) violation. The associated two-state Hamiltonian is… Expand
