RANDOM-MATRIX THEORIES IN QUANTUM PHYSICS : COMMON CONCEPTS

- T. Guhr, A. Mueller-Groeling, H. Weidenmueller
- Physics, Mathematics
- 29 July 1997

We review the development of random-matrix theory (RMT) during the last fifteen years. We emphasize both the theoretical aspects, and the application of the theory to a number of fields. These… 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

Perturbation theory for the effective interaction in nuclei

- T. H. Schucan, H. Weidenmueller
- Physics
- 1 April 1973

Abstract Starting from a decomposition of the Hamiltonian H(x) of the nuclear many-body problem in the form H(x) = H0 + xV, where H0 is a shell-model Hamiltonian, V the residual interaction, and x a… Expand

Colloquium: Random matrices and chaos in nuclear spectra

- T. Papenbrock, H. Weidenmueller
- Physics
- 30 January 2007

Chaos occurs in quantum systems if the statistical properties of the eigenvalue spectrum coincide with predictions of random-matrix theory. Chaos is a typical feature of atomic nuclei and other… Expand

Introduction to the theory of heavy-ion collisions

- W. Nörenberg, H. Weidenmueller
- Physics
- 1976

Some basic tools of theoretical heavy-ion physics are presented. Topics covered include: classical theory of heavy ion collisions; gross properties of heavy ion reactions, compound nucleus formation;… Expand

The effective interaction in nuclei and its perturbation expansion: An algebraic approach

- T. H. Schucan, H. Weidenmueller
- Physics
- 1 September 1972

Abstract We consider a finite-dimensional model for the Hilbert space of the A -nucleon problem. In the frame of this model we explicitly construct the energy-independent effective interaction W… Expand

Stochastic versus semiclassical approach to quantum chaotic scattering

- C. Lewenkopf, H. Weidenmueller
- Physics
- 15 November 1991

Abstract We explore the universal features of quantum scattering systems for which the classical scattering is chaotic. We do so by comparing the semiclassical approach and the stochastic approach,… Expand

Induced violation of time-reversal invariance in the regime of weakly overlapping resonances.

- B. Dietz, T. Friedrich, +5 authors H. Weidenmueller
- Physics, Medicine
- Physical review letters
- 9 February 2009

We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal (T) invariance is partially broken by a magnetized ferrite placed within the cavity. We… Expand
