Evidence against the wobbling nature of low-spin bands in 135Pr
2021
International audience; The electromagnetic character of the ΔI=1 transitions connecting the 1- to 0-phonon and the 2- to 1-phonon wobbling bands should be dominated by an E2 component, due to the collective motion of the entire nuclear charge. In the present work it is shown, based on combined angular correlation and linear polarization measurements, that the mixing ratios of all analyzed connecting transitions between low-lying bands in 135Pr interpreted as 0-, 1-, and 2-phonon wobbling bands, have absolute values smaller than one. This indicates predominant M1 magnetic character, which is incompatible with the proposed wobbling nature. All experimental observables are instead in good agr…
Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
Tracce di ‘improbus intestabilisque’ nella Parafrasi di Teofilo e nei Basilici
2017
The research is a part of a wider study on the improbitas and the so called intestabilitas in the Roman sources and focuses on analysis of a passage of the Theophilus’Paraphrase (2.10.6) and some σχόλια added to the Basilica [especially, Sch. 1 ad Bas. 39.1(Pb).6 e Sch. 3 ad Bas. 21.1(Pa).14] – texts that have not been taken into account (except for PT. 2.10.6 only) by the scholars who studied the implications associated with the improbus intestabilisque esse. The Author aims to verify the presence of traces of that institute in the aforementioned Byzantine sources, which may be useful for a more complete reconstruction of the historical evolution of the Roman formulaic improbus intestabili…
