Two uniaxial spin transfer oscillators with field coupling and RLC loads are considered. This system can demonstrate synchronized as well non-synchronized oscillations. There is an area of bistability in the parameter space where these two regimes coexist. The mechanism control suggested. It shown that if circuits tuned such a way after start their currents slowly monotonically decay from high ...

Nonlinear devices, such as transistors, enable contemporary computing technologies. We theoretically investigate nonlinear effects, bearing a high fundamental scientific and technical relevance, in magnonics with emphasis on superconductor-ferromagnet hybrids. Accounting for finite magnon chemical potential, we demonstrate magnonic spin Joule heating, the analog of conventional electronic heati...

The present work focuses on experimental investigations of a bistabile silicon-on-insulator (SOI) micro-ring resonator (MRR). exploits continuous-wave operation the carrier-induced bistability demonstrating stable hysteresis response at through and drop ports when input power exceeds threshold value. Flipping optical provides convenient mechanism for switching MRR output characteristics between...

Multistability is a fundamental attribute of the dynamics of neuronal systems under normal and pathological conditions. The mechanism of bistability of bursting and silence is not well understood and to our knowledge has not been experimentally recorded in single neurons. We considered four models. Two of them described the dynamics of a leech heart interneuron: the canonical model and a low-di...
