Josephson-junction-based axion detection through resonant activation
2022
We discuss the resonant activation phenomenon on a Josephson junction due to the coupling of the Josephson system with axions. We show how such an effect can be exploited for axion detection. A nonmonotonic behavior, with a minimum, of the mean switching time from the superconducting to the resistive state versus the ratio of the axion energy and the Josephson plasma energy is found. We demonstrate how variations in switching times make it possible to detect the presence of the axion field. An experimental protocol for observing axions through their coupling with a Josephson system is proposed.
Generation of travelling sine-Gordon breathers in noisy long Josephson junctions
2022
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of losses, a current bias, and a thermal noise source. We demonstrate how to exclusively induce breather modes by means of controlled magnetic pulses. A nonmonotonic behavior of the breather-only generation probability is observed as a function of the noise intensity. An experimental protocol providing evidence of the Josephson breather's existence is proposed.
Ac-locking of thermally-induced sine-Gordon breathers
2023
A complete framework for exciting and detecting thermally-induced, stabilized sine-Gordon breathers in ac-driven long Josephson junctions is developed. The formation of long-time stable breathers locked to the ac source occurs for a sufficiently high temperature. The latter emerges as a powerful control parameter, allowing for the remarkably stable localized modes to appear. Nonmonotonic behaviors of both the breather generation probability and the energy spatial correlations versus the thermal noise strength are found. The junction's resistive switching characteristics provides a clear experimental signature of the breather.
Electron structure, ultra-dense hydrogen and low energy nuclear reactions
2019
In this paper, a simple Zitterbewegung electron model, proposed in a previous work, is presented from a different perspective based on the principle of mass- frequency equivalence. A geometric- electromagnetic interpretation of mass, relativistic mass, De Broglie wavelength, Proca, Klein- Gordon, Dirac and Aharonov- Bohm equations in agreement with the model is proposed. A non-relativistic, Zitterbewegung interpretation of the 3.7 keV deep hydrogen level found by J. Naudts is presented. According to this perspective, ultra-dense hydrogen can be conceived as a coherent chain of bosonic electrons with protons or deuterons located in the center of their Zitterbewegung orbits. This approach sug…
Arte Tedesca e Arte Degenerata. Aspetti della politica culturale del Terzo Reich
2011
Il saggio prende le mosse dalle iniziative intraprese da Joseph Goebbels nell'ambito dell'organizzazione culturale in Germania, durante i primi mesi del "nuovo corso" nazista. Fra i vari temi, vengono affrontate le questioni relative alle rapporto con la cultura della Repubblica di Weimar, alle grandi mostre di Monaco (Entartete Kunst, 1937) e Duesselforf (Entartete Musik, 1938), nonché della produzione musicale all'interno del ghetto di Theresienstadt.
Benedetto XVI e il compito urgente dell’educazione
2015
All’origine della riflessione sull’urgenza di una Nuova Evangelizzazione ci sta la constatazione di una diffusa situazione di crisi di valori cristiani e educativi, percepibili soprattutto nei Paesi di antica cristianità. Più volte, nei suoi discorsi, Benedetto XVI concentra l’attenzione sulla necessità di educazione: in primo luogo dei genitori «preoccupati e spesso angosciati per il futuro dei loro figli» degli insegnanti «che vivono la triste esperienza del degrado delle scuole» e della società stessa «che vede messe in dubbio dalla crisi dell’educazione le basi stesse della convivenza». Si evidenzia la necessità dell’educazione principalmente per le nuove generazioni. Ma la percezione d…
Dissipation and entanglement dynamics for two interacting qubits coupled to independent reservoirs
2008
We derive the master equation of a system of two coupled qubits by taking into account their interaction with two independent bosonic baths. Important features of the dynamics are brought to light, such as the structure of the stationary state at general temperatures and the behaviour of the entanglement at zero temperature, showing the phenomena of sudden death and sudden birth as well as the presence of stationary entanglement for long times. The model here presented is quite versatile and can be of interest in the study of both Josephson junction architectures and cavity-QED.
