Resistive switching dynamics in current-biased YBa2Cu3O7Àx microbridges excited by nanosecond electrical pulses
We report our studies on the time-resolved dynamics of the superconducting-to-resistive transition in dcbiased epitaxial YBa2Cu3O72x ~YBCO! microbridges, excited by nanosecond-long current pulses. Our experimental structures consisted of 200-nm-thick epitaxial YBCO films deposited on MgO substrates. They were patterned into a single 25 mm by 50 mm microbridge, embedded in the middle of a coplan...
متن کاملResistive Switching Dynamics in Current-Biased Y-Ba-Cu-O Microbridges Excited by Nanosecond Electrical Pulses
40 LLE Review, Volume 89 The response of a superconductor to the injection of current pulses depends directly on the quasiparticle dynamics1 since the carriers injected from the external circuit are normal (unpaired) electrons that disturb the quasiparticle–Cooperpair dynamical equilibrium. Most commonly, a current pulse with an amplitude higher than the sample critical current Ic is used (supe...

متن کاملBiased sampling of nonequilibrium trajectories: can fast switching simulations outperform conventional free energy calculation methods?
We have investigated the maximum computational efficiency of reversible work calculations that change control parameters in a finite amount of time. Because relevant nonequilibrium averages are slow to converge, a bias on the sampling of trajectories can be beneficial. Such a bias, however, can also be employed in conventional methods for computing reversible work, such as thermodynamic integra...
متن کاملClimates and clades: biased methods, biased results
Thuiller et al. analyzed the consequences of anticipated climate change on plant, bird, and mammal phylogenetic diversity (PD) across Europe. They concluded that species loss will not be clade specific across the Tree of Life, and that there will not be an overall decline in PD across the whole of Europe. We applaud their attempt to integrate phylogenetic knowledge into scenarios of future exti...
