Transient Dynamics of d-Wave Superconductors after a Sudden Excitation.
Motivated by recent ultrafast pump-probe experiments on high-temperature superconductors, we discuss the transient dynamics of a d-wave BCS model after a quantum quench of the interaction parameter. We find that the existence of gap nodes, with the associated nodal quasiparticles, introduces a decay channel which makes the dynamics much faster than in the conventional s-wave model. For every va...
متن کاملNonequilibrium Dynamics in Cuprate Superconductors using Transient Grating Spectroscopy
Transient grating spectroscopy is an excellent method for probing the dynamics of quasiparticles in high-temperature superconductors, which are key to understanding the mechanism behind superconductivity in such materials. Femtosecond optical pulses provide timeresolved measurements of reflectivity. When combined with nonuniform excitation due to the diffraction grating, this technique can effe...
متن کاملtransient sudden bilateral visual loss after orthotopic heart transplantation: a case report
post cardiac surgery ophthalmic complications are uncommon, and sudden visual loss is one of the most important ophthalmic problems in these patients. we report a 54-year-old woman that suffered transient sudden bilateral visual loss seven days after orthotopic heart transplantation. in ophthalmologic examination positive findings were bilateral normal size pupils without direct and indirect pu...
متن کاملExcitation of Transient Rossby Waves on the Stratospheric Polar Vortex and the Barotropic Sudden Warming
The excitation of Rossby waves on the edge of the stratospheric polar vortex, due to time-dependent topographic forcing, is studied analytically and numerically in a simple quasigeostrophic f-plane model. When the atmosphere is compressible, the linear response of the vortex is found to have two distinct components. The first is a spectrum of upward-propagating waves that are excited by forcing...
متن کاملTransient implicit wave propagation dynamics with overlapping finite elements
We present novel overlapping finite elements used with the Bathe time integration method to solve transient wave propagation problems. The solution scheme shows two important properties that have been difficult to achieve in the numerical solution of general wave propagations: monotonic convergence of calculated solutions with decreasing time step size and a solution accuracy almost independent...
