Niemcy, Rosja i kwestia polska w publicystyce Jędrzeja Giertycha na łamach "Horyzontów" paryskich (1956-1971)
2017
The liberalization of the communist system in mid-1950s, disillusionment with the policy of the West, fears connected with West German revisionism, and dwindling chances of change in the situation of Central-Eastern Europe contributed to a differentiation of attitudes among the Polish emigrants. Some of them, notably the nationalists, voiced the need to seek compromise with Russia. This led to the emergence of a pro-Russian option alongside the still dominant pro-Western one. The thesis on the need of an alliance with Russia was propagated by Jędrzej Giertych in his jo umalism in the "Horyzonty” monthly published in Paris. This ideologically committed opponent of communism and a staunch Cat…
Polski rok 1989 w perspektywie czechosłowackich dzienników opiniotwórczych
2019
The main goal of this article is to show the image of most important Polish political actions in 1989 through the prism of Czechoslovak opinion - forming daily press: Rude pravo and Mlada fronda. The author is focused on the analysis of materials generally connected with the deliberations of the Round Table, as well as the Polish legislative election on 4 June. It is desirable to disclose the way of presenting of the most important actions in Poland by the Czechoslovak press in that period, which we have mentioned above. The author also tries to determine how acute was the attention of the press to the Polish events that had taken place during those times. The newspapers, that are analysed,…

Phosphorous doping and drawing effects on the Raman spectroscopic properties of O=P bond in silica-based fiber and preform.
2012
International audience; We report an experimental study of the doping and drawing effects on the Raman activities of phosphorus (P)-doped silica-based optical fiber and its related preform. Our data reveal a high sensitivity level in the full width at half maximum value of the 1330 cm−1 (O = P) Raman band to the P-doping level. Its increase with the P doping level does not clash with an increase in the disorder of the O = P surrendering matrix. In addition, we observe that in the central core region of the sample (higher doping level), the drawing process decreases the relative band amplitude. We tentatively suggest that this phenomenon is due to the change in the first derivate of the bond…
Józef Wacław Dąbrowski (1797–1862). Wołynianin w armii Królestwa Polskiego
2021
W artykule, w oparciu o nieznane i tym samym niewykorzystywane dotąd przez historyków wspomnienia, przedstawione zostały dzieciństwo i młodość Józefa Wacława Dąbrowskiego, oficera wojska Królestwa Polskiego, dowódcę w randze kapitana i majora oddziałów powstańczych jesienią 1830 – latem 1831 r. Koleje jego losów i kariera wojskowa są tak typowe, jak i odbiegające od znanych i omawianych w literaturze przedmiotu schematów. Typowe, gdyż dzięki wywodzeniu się z kręgów średnio zamożnego ziemiaństwa rozpoczął służbę wojskową od stopnia kadeta, aby przed upływem roku awansować na podchorążego i uzyskać skierowanie do szkoły podchorążych, stanowiącej niezbędny etap służby potrzebny do awansu ofice…
Reinforcement learning approach to nonequilibrium quantum thermodynamics
2021
We use a reinforcement learning approach to reduce entropy production in a closed quantum system brought out of equilibrium. Our strategy makes use of an external control Hamiltonian and a policy gradient technique. Our approach bears no dependence on the quantitative tool chosen to characterize the degree of thermodynamic irreversibility induced by the dynamical process being considered, require little knowledge of the dynamics itself and does not need the tracking of the quantum state of the system during the evolution, thus embodying an experimentally non-demanding approach to the control of non-equilibrium quantum thermodynamics. We successfully apply our methods to the case of single- …
Work fluctuations in bosonic Josephson junctions
2016
We calculate the first two moments and full probability distribution of the work performed on a system of bosonic particles in a two-mode Bose-Hubbard Hamiltonian when the self-interaction term is varied instantaneously or with a finite-time ramp. In the instantaneous case, we show how the irreversible work scales differently depending on whether the system is driven to the Josephson or Fock regime of the bosonic Josephson junction. In the finite-time case, we use optimal control techniques to substantially decrease the irreversible work to negligible values. Our analysis can be implemented in present-day experiments with ultracold atoms and we show how to relate the work statistics to that…
Discrete spectral incoherent solitons in nonlinear media with noninstantaneous response
2011
International audience; We show theoretically that nonlinear optical media characterized by a finite response time may support the existence of discrete spectral incoherent solitons. The structure of the soliton consists of three incoherent spectral bands that propagate in frequency space toward the low-frequency components in a discrete fashion and with a constant velocity. Discrete spectral incoherent solitons do not exhibit a confinement in the space-time domain, but exclusively in the frequency domain. The kinetic theory describes in detail all the essential properties of discrete spectral incoherent solitons: A quantitative agreement has been obtained between simulations of the kinetic…
Random Tensor Theory: Extending Random Matrix Theory to Mixtures of Random Product States
2012
We consider a problem in random matrix theory that is inspired by quantum information theory: determining the largest eigenvalue of a sum of p random product states in $${(\mathbb {C}^d)^{\otimes k}}$$ , where k and p/d k are fixed while d → ∞. When k = 1, the Marcenko-Pastur law determines (up to small corrections) not only the largest eigenvalue ( $${(1+\sqrt{p/d^k})^2}$$ ) but the smallest eigenvalue $${(\min(0,1-\sqrt{p/d^k})^2)}$$ and the spectral density in between. We use the method of moments to show that for k > 1 the largest eigenvalue is still approximately $${(1+\sqrt{p/d^k})^2}$$ and the spectral density approaches that of the Marcenko-Pastur law, generalizing the random matrix…
