Phase sticking in one-dimensional Josephson junction chains
2013
Published version of an article in the journal: Physical Review B - Condensed Matter and Materials Physics. Also available from the publisher at: http://dx.doi.org/10.1103/PhysRevB.88.104501 We studied current-voltage characteristics of long one-dimensional Josephson junction chains with Josephson energy much larger than charging energy, EJ EC. In this regime, typical I-V curves of the samples consist of a supercurrent-like branch at low-bias voltages followed by a voltage-independent chain current branch, Ichain at high bias. Our experiments showed that Ichain is not only voltage-independent but it is also practically temperature-independent up to T=0.7TC. We have successfully model the tr…
Joseph Conrad-Korzeniowski, czyli polska dusza w literaturze angielskiej
2016
Joseph Conrad wniósł do literatury angielskiej prawdziwie polską duszę i fantazję. Ostatni z polskich romantyków, jak sam siebie nazwał, wprowadził do światowej literatury polskie dylematy, rozterki i wątpliwości, a także tęsknoty i pragnienia. Conrad przeniósł polskie doświadczenie na poziom uniwersalny i takim owo doświadczenie również uczynił. Rozmaite relacje współczesnych ukazują, jak niejednokrotnie trudno było odnaleźć się Polakowi w anglosaskiej rzeczywistości, i z jakimi przeciwnościami musiał się zmierzyć.
Conrad Andrzeja Buszy
2019
The article presents Professor Andrzej Busza, a Conradian researcher, who is connected with the subject of his research, Joseph Conrad, by common experiences of alienation and growing into a different culture, life on the border of different worlds. Busza presents Conrad’s Polish heritage and its later influence on the writer’s work. Busza writes about Conrad ’s deep pessimism, which links the writer with contemporary Poles, as well as about Conrad’s popularity during the war and occupation, when“ fidelity becomes the greatest of virtues, and betrayal - the greatest crime” . Busza also speaks of Conrad’s attitude to Flaubert and Dostoyevsky, which, being fuli of paradoxes and contradictions…
Olleros, alfareros y fabricantes de loza en Ribesalbes, entre 1742 y 1817
2012
El desarrollo de la tradición alfarera en Ribesalbes, y el posterior establecimiento de las primeras fábricas de loza, a finales del siglo XVIII, viene determinado por los condicionantes naturales e históricos de la villa; así como por la influencia decisiva de la Real Manufactura del conde de Aranda, en la vecina población de L’Alcora. En este trabajo, a partir de diversas fuentes documentales primarias, entre las que cabe destacar los libros sacramentales del Archivo Parroquial de Ribesalbes, y la Contribución general de 1817, se constata la presencia de olleros en la Baronía, a principios del siglo XVIII. Se determinan también los nombres de algunos alfareros, registrados en los albores …
Anomalous transport effects on switching currents of graphene-based Josephson junctions
2017
We explore the effect of noise on the ballistic graphene-based small Josephson junctions in the framework of the resistively and capacitively shunted model. We use the non-sinusoidal current-phase relation specific for graphene layers partially covered by superconducting electrodes. The noise induced escapes from the metastable states, when the external bias current is ramped, give the switching current distribution, i.e. the probability distribution of the passages to finite voltage from the superconducting state as a function of the bias current, that is the information more promptly available in the experiments. We consider a noise source that is a mixture of two different types of proce…
Switching times in long-overlap Josephson junctions subject to thermal fluctuations and non-Gaussian noise sources
2014
We investigate the superconducting lifetime of long current-biased Josephson junctions, in the presence of Gaussian and non-Gaussian noise sources. In particular, we analyze the dynamics of a Josephson junction as a function of the noise signal intensity, for different values of the parameters of the system and external driving currents. We find that the mean lifetime of the superconductive state is characterized by nonmonotonic behavior as a function of noise intensity, driving frequency and junction length. We observe that these nonmonotonic behaviours are connected with the dynamics of the junction phase string during the switching towards the resistive state. An important role is played…
Nonadiabatic dynamics in strongly driven diffusive Josephson junctions
2019
By measuring the Josephson emission of a diffusive Superconductor-Normal metal-Superconductor (SNS) junction at a finite temperature we reveal a non-trivial sensitivity of the supercurrent to microwave irradiation. We demonstrate that the harmonic content of the current-phase relation is modified due to the energy redistribution of quasiparticles in the normal wire induced by the electromagnetic field. The distortion originates from the phase-dependent out-of-equilibrium distribution function which is strongly affected by the ac-response of the spectral supercurrent. For phases close to $\pi$, transitions accross the Andreev gap are dynamically favored leading to a supercurrent reduction. T…
No Entrepreneurship without Opportunity: The Intersection of Return Migration Research and Entrepreneurship Literature
2019
Abstract The article proposes a theoretical discussion at the crossroads of the return migration scholarship with the entrepreneurship research. Its main goal is to build an analytical framework in which entrepreneurial experiences of international return migrants are conceptualized. The fertile theoretical legacy within the study of entrepreneurship along with an idealized view of the positive effects of migration constitute essential premises for understanding the biased outputs of the empirical studies of entrepreneurship upon return to the origin country. Firstly, the article draws on the main lines of theorising opportunities within the Weberian and Schumpeterian theoretical traditions…
Horseshoe-shaped maps in chaotic dynamics of long Josephson junction driven by biharmonic signals
2000
Abstract A collective coordinate approach is applied to study chaotic responses induced by an applied biharmonic driven signal on the long Josephson junction influenced by a constant dc-driven field with breather initial conditions. We derive a nonlinear equation for the collective variable of the breather and a new version of the Melnikov method is then used to demonstrate the existence of Smale horseshoe-shaped maps in its dynamics. Additionally, numerical simulations show that the theoretical predictions are well reproduced. The subharmonic Melnikov theory is applied to study the resonant breathers. Results obtained using this approach are in good agreement with numerical simulations of …
Vintage violence. La strana violenza del cinema di Losey
2015
Los textos sobre la violencia tienden a dar por sentado este concepto. En este artículo se intentará esbozar una definición semiótica a través de una breve relectura de algunos clásicos y de algunas entradas de vocabulario, para sugerir una caracterización de la violencia como dispositivo semiótico: una articulación de dos figuras diferentes de agresión («laceración»/«constricción») contra un umbral convencional. Esta hipótesis se desarrolla en el análisis de las películas de Joseph Losey, donde la violencia aparece de muchas formas, pero nunca llega a ser (con raras excepciones) totalmente explícita o espectacular. El artículo reconsidera el análisis de Gilles Deleuze en L’Image-Mouvement,…
