Mutual Phase Locking of Very Nonidentical Spin Torque Nanooscillators via Spin Wave Interaction
In this paper the mutual phase locking theory of very nonidentical
spin-torque nanooscillators, which is based on the Slavin-Tiberkevich model,
considering the theory of nonlinear oscillations, is developed. Using
generalized Adler equation we calculate phase-locking region of the system with
spinwave coupling in the parameter plane - distance between nanocontacts and
radii difference. We describe trajectories of such a system in the phase space
and show the effect of a broadband synchronization. We introduce a
generalization of this approach to the ensembles of spin-torque nanooscillatorsComment: 6 pages, 2 figure
Progress in classically solving ten dimensional supersymmetric reduced Yang-Mills theories
It is shown that there exists an on-shell light cone gauge where half of the
fermionic components of the super vector potential vanish, so that part of the
superspace flatness conditions becomes linear. After reduction to
space-time dimensions, the general solution of this subset of equations is
derived. The remaining non-linear equations are written in a form which is
analogous to Yang equations, albeit with superderivatives involving sixteen
fermionic coordinates. It is shown that this non-linear part may, nevertheless,
be solved by methods similar to powerful technics previously developed for the
(purely bosonic) self-dual Yang Mills equations in four dimensions.Comment: 17 pages Latex non figure
