Laser-Matter Interaction: Classical Regime versus Quantum Regime
Adriana Pálffy, Paul-Gerhard Reinhard, Hans A. Weidenmüller
Doppler backscattering of optical laser photons on a "flying mirror" of relativistic electrons promises to yield coherent photons with MeV-range energies. We compare the nuclear in…
Laser-Nucleus Interactions: The Quasiadiabatic Regime
Adriana Pálffy, Oliver Buss, Axel Hoefer +1
The interaction between nuclei and a strong zeptosecond laser pulse with coherent MeV photons is investigated theoretically. We provide a first semi-quantitative study of the quasi…
Neutron Resonance Widths and the Porter-Thomas Distribution
Alexander Volya, Hans A. Weidenmüller, Vladimir Zelevinsky
Experimental evidence has recently put the validity of the Porter-Thomas distribution (PTD) for partial neutron widths into question. We identify two terms in the effective Hamilto…
Doorway States in the Random-Phase Approximation
A. De Pace, A. Molinari, H. A. Weidenmueller
By coupling a doorway state to a see of random background states, we develop the theory of doorway states in the framework of the random-phase approximation (RPA). Because of the s…
Laser-Nucleus Reactions: Population of States far above Yrast and far from Stability
A. Pálffy, H. A. Weidenmüller
Nuclear reactions induced by a strong zeptosecond laser pulse are studied theoretically in the quasiadiabatic regime where the photon absorption rate is comparable to the nuclear e…
Effective Field Theory for Finite Systems with Spontaneously Broken Symmetry
T. Papenbrock, H. A. Weidenmueller
We extend effective field theory to the case of spontaneous symmetry breaking in genuinely finite quantum systems such as small superfluid systems, molecules or atomic nuclei, and…
