Super-radiance: from Nuclear Physics to Pentaquarks *
نویسندگان
چکیده
The phenomenon of super-radiance in quantum optics predicted by Dicke 50 years ago and observed experimentally has its counterparts in many-body systems on the borderline between discrete spectrum and continuum. The interaction of overlapping resonances through the continuum leads to the redistribution of widths and creation of broad super-radiant states and long-lived compound states. We explain the physics of super-radiance and discuss applications to weakly bound nuclei, giant resonances and widths of exotic baryons.

On classical super-radiance in Kerr-Newman-anti-de Sitter black holes
We study in detail the modes of a classical scalar field on a KerrNewman-anti-de Sitter (KN-AdS) black hole. We construct sets of basis modes appropriate to the two possible boundary conditions (“reflective” and “transparent”) at time-like infinity, and consider whether super-radiance is possible. If we employ “reflective” boundary conditions, all modes are non-super-radiant. On the other hand,...
متن کاملA unified analysis of spontaneous and super-radiant emissions in free-electron lasers
A generalized formulation of spontaneous emission and super-radiance effects in a free-electron laser is presented. We consider a stream of electrons of arbitrary temporal duration propagating through the undulator. The sum of the undulator synchrotron radiation emitted by individual wiggling electrons entering the wiggler at random, results in shot-noise in the radiation field. Using the waveg...
متن کاملWhy Do We Need Instantons in Strangeness Hadron Physics?
Strangeness nuclear physics has reached a new era, which requires elevation of phenomenological analyses of hypernuclear phenomena to a deeper understanding of the fundamental interactions from QCD viewpoint. Recent coordinated efforts in experimental and theoretical researches revealed several interesting features of hyperon-nucleon and hyperon-hyperon interactions. For instance, it is establi...
متن کاملStructure and Light Emission of a Strömgren System
Stroemgren defined a model made up of an extremely hot source plunged in a constant density, huge, static cloud of low pressure hydrogen. The present studies of this model apply qualitatively with relatively small and cold sources, but without these assumptions, we must take into account that:-the source has, at all frequencies, the spectral radiance of a laser at a single frequency, so that th...
متن کامل“Super-radiance” and the width of exotic baryons
It is suggested that the narrow width of the recently observed resonance Θ+(1540) with strangeness S = +1 could be a result of the super-radiance mechanism of the redistribution of the widths of overlapping resonances due to their coupling through common decay channels.
