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

- 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
