Hidden dynamics in models of discontinuity and switching
No full textSharp switches in behaviodr, like impacts, stick slip motion, or electrical relays, can be modelled by differential equations with discontinuities. A discontinuity approximates fine details of a switching process that lie beyond a bulk empirical model. The theory of piecewise-smooth dynamics describes what happens assuming we can solve the system of equations across its discontinuity. What this typically neglects is that effects which are vanishingly small outside the discontinuity can have an arbitrarily large effect at the discontinuity itself. Here we show that such behaviour can be incorporated within the standard theory through nonlinear terms, and these introduce multiple sliding modes. We show that the nonlinear terms persist in more precise models, for example when the discontinuity is smoothed out. The nonlinear sliding can be eliminated, however, if the model contains an irremovable level of unknown error, which provides a criterion for systems to obey the standard Filippov laws for sliding dynamics at a discontinuity.

Spin: from basic symmetries to quantum optimal control
No full textThis monograph is a fundamental reference for scientists and engineers who encounter spin processes in their work. The author, Ilya Kuprov, derives the concept of spin from basic symmetries and gives an overview of theoretical and computational aspects of spin dynamics: from Dirac equation and spin Hamiltonian, through coherent evolution and relaxation theories, to quantum optimal control, and all the way to practical implementation advice for parallel computers

Ilya Grubert, violín (Rusia)
No full textConcierto interpretado por Ilya Grubert acompañado en el piano de Boris Slutsky. Ilya el destacado violinista soviético nació en 1954 en Riga, donde vivió los primeros nueve años de su entrenamiento musical en la Escuela Especial de Música E. Darzin. La audiencia conoció su capacidad interpretativa cuando el joven Grubert hizo su debut como solista a los 14 años. Reconocido como un estudiante de talento excepcional, el difunto Yuri Yankelvich, un pedagogo del violín mundialmente renombrado, aceptó a Grubert en su clase de la Escuela Central en Moscú y después en el Conservatorio de Moscú.
En este concierto interpretaron obras de J.S. Bach, Eugene Ysaye, Frédéríc Chopín, Mauríce Ravel, César Franck y Franz Waxman
